Q: I start PQV and it immediately exits; what is going on?
A: By default, PQV tries to cache thumbnails of all the image files it finds in "\My Documents". If there is a file which causes PQV to crash, the program will exit without indicating what happened. Try temporarily moving the files out of the \My Documents directory to see which one is making it fail. Please email me any such files so that I can correct the problem.
Q: Why does loading an image from Compact Flash take so long?
A: Compact Flash memory is much slower than RAM and the hardware interface to the CF card is not very efficient. Loading images from CF memory can take many times longer to load than from RAM. If you need quick access to your images, copy them to RAM.
Q: Can I add sound or notes to my slideshows?
A: Yes, PQV now supports playing WAV files during the slideshow. They can be recorded from within PQV.
Q: Why do I get an error about bit depth when I try to save an image to a certain file format?
A: Certain file formats are restricted to handle only specific pixel bit depths. Use the color modification function to convert the image to a compatible bit depth.
Q: How do I jump to a specific page in a multi-page file?
A: Click on the icon which displays the current page number; a dialog box will appear allowing you to select the page to go to.
Q: How can I undo changes I make to an image?
A: PQV is not a paint program and does not allow undoing changes. Reload the original image to undo any changes you have made.
Q: When I take screen shots, I hear the shutter noise, but can't find any files being created; where are they?
A: Check that the root filename and destination directory will create valid path names for the captured image files.
Q: How can I delete unwanted images?
A: PQV allows deletion and renaming of images from the thumbnail and main window or from a toolbar icon. Tap and hold the stylus (Alt-click for HPC) and a context menu will be displayed.
Q: The image I'm viewing is displayed in the wrong orientation; how do I fix it?
A: PQV can rotate the image in 90 degree increments as well as flip it horizontally and vertically; the second toolbar contains these functions.
Q: I tried to open a PDF file, but PQV displayed it wrong or gave an error message of "page not found"; what's the story?
A: PQV currently contains limited support for viewing PDF files. It searches the PDF file for images and each image becomes a 'page'. This will only work well for PDF files which are basically scanned images with no text or graphics. If Adobe does not release a free PDF viewer for CE, I may enhance this feature, but for now this is it.
Q: Why can't I send an email attachment from within PQV on my HPC?
A: Apparently the HPC inbox application only allows sending file attachments from within the inbox program.
Q: I have encountered an image that PQV should be able to view, but is not able to view correctly, what should I do?
A: Please email the image to bitbank@pobox.com. If it is a supported file type, a correction to PQV will be made in the next release.
Q: I opened a 4 megapixel photo, but when I check the image info it shows it's 1/4 the size I expected; what went wrong?
A: There are two reasons this may have occurred: either you have the JPEG options set to load images at 1/4 size or your machine ran out of memory opening the full sized image, so PQV loaded it at 1/4 size to fit the available memory.
Q: I rotated an image and then saved it, but the saved image was not rotated; what am I doing wrong?
A: There are 2 rotate functions - one only affects the view, the other affects the actual image data.
How to use the Batch Process Feature
PQV
3.0 has a very powerful feature which digital camera owners will find especially
useful. The batch process feature allows you to tag images for
copy/resize/crop/convert/rotate/delete. Once tagged, you begin the batch
process and watch as it works on a whole directory of images in one simple
operation. Any image opened in the main window can be tagged for these
operations by either doing a tap&hold and selecting options from the TAG menu or
from the 6th toolbar. The tags will show up as small icons in the corner
of the main window and the thumbnail image. The option "Tag all = this"
means to tag all images in the current directory with the tags of the current
image. The resize and convert tags refer to options set in the preferences
dialog, BATCH page. The DELETE tag may seem
redundant since you can also delete the image from the context menu, but it is
actually quicker to select this tag from the 6th toolbar with a single tap and
it can also be untagged if you change your mind later. This feature is
especially useful for those on the road who need to prepare camera images for
web pages or for doing slide shows. In one operation you can copy and
resize your images while retaining high quality.
How to Work with Large JPEG Images
Many of
the latest digital cameras can produce huge images (3, 4 or 5 megapixels).
To decompress and display these images PQV has several options to accelerate the
process and use less memory. For example, a 4 megapixel image is typically
2272 x 1704. When decompressed to a 24-bit color image, this will occupy
11.6MB of memory. This amount of memory is not always available and
expanding the image to its full size will take several seconds. The
recommended way to work with these images (if you do not intend to edit and
resave them) is to load them at 1/4 size and at 16 bits per pixel. These
options are available on the
JPEG tab of the preferences window. At 1/4 size
and 16-bits per pixel, that same image will look just as good on the Pocket PC
display and only use 1.9MB of memory; it will also load much quicker.
There is no perceptible loss of quality because PQV uses a pixel averaging
technique when photos are loaded at reduced size.
How to Losslessly Rotate JPEG Images
The
majority of JPEG images use what is called a "lossy" compression technique.
What this means is that compressing and decompressing an image will not result
in an exact replica of the original. The "quality level" controls how much
loss occurs; the lower the quality level, the higher the amount of compression.
It is often the case that images captured by digital cameras are not displayed
in the same orientation in which they are captured (holding the camera rotated).
Some new cameras such as the Canon S45 account for this by storing the image in
the new orientation, but most will store the image "wrong". Opening, rotating and
saving the image, causes a degradation in quality due to the lossy nature of the
compression. However, it is possible to rotate a JPEG image without
incurring a loss of quality. The technique involves decompressing the
image "half-way" and then recompressing it in the new orientation. This
process requires more memory than the decompressed image normally would.
It is possible to do this while using little memory, but that would require
multiple passes through the image and take an enormous amount of time.
Therefore, when using this feature, ensure that there is sufficient free memory. Typical memory requirements: 4 MegaPixel image ~= 15.3MB,
3 MegaPixel image ~= 12.4MB. This feature will be employed during the batch
process when the only operation on an image is rotation. Note that EXIF
header information will be preserved after rotation, but any embedded thumbnail
image will not be rotated. This may make you think that the image has not
been rotated when you see the thumbnail appear in PQV, but open it and you will
see its true orientation.
Digital camera
manufacturers have agreed on a standard way to include detailed information in
digital photos. The standard used is called EXIF and stands for
Exchangeable Image File Format. The data is added to the image file in
such a way that it can be ignored or removed without affecting the image data.
The data usually includes information about the camera and about the conditions
of the captured image. There is also an optional thumbnail image that PQV
uses if present. To view the EXIF info in PQV, open a photo in the main
window and select "Photo Info..." from the FILE menu. The display will
show the important details of the photo such as shutter speed and F stop as well
as a histogram of the image intensity. The histogram is useful to see if
the picture is over or underexposed. Loading JPEG images with the 16-bit
color option will cause the histogram to be coarser than when loaded as 24-bits
per pixel.
PQV has an optional graphical toolbar at the bottom of the display. This toolbar is actually 10 separate toolbars. To switch through the toolbars, press the green arrow icons on the menu or jump to a specific toolbar through the "toolbar" menu. Clicking the green arrow at the last toolbar will return to the first. Each toolbar can be customized (including its name).
The toolbar has a help feature called 'Tool Tips'. To see the function of a toolbar icon, tap and hold the stylus over the toolbar icon of interest. A small yellow window will display the function of that icon. When the stylus is released, the help will disappear.
Begin by clicking on the 'Open' toolbar icon (the leftmost icon on the first toolbar); a file selector will be displayed. At the top of the file selector is a drop-down control with the name of the current directory. Click on this name to display the directory hierarchy and select a different directory. When the desired directory is reached, the main listview will show the names of subdirectories followed by the files within the current directory. The list of files is filtered by another drop-down control below the main file list. For example: if one is interested in only seeing JPEG files, select "JPEG" from the file filter drop-down list and the file list will be reset and filled with only JPEG files. The names can also be sorted by Name, Size or Date.
At the bottom of the file selector is a preview window. This allows one to see a miniature version of an image before committing to opening it. This feature has been optimized for JPEG files and can view them extremely quickly. Selecting a filename from the listview with a single click will display it in the preview window. Next to the preview window are displayed the actual image size in pixels and file size in bytes.
To open the selected filename, click on the Open button or the preview window. This will dismiss the file selector and open the image in PQV's main window. You may also click the "Open" button without choosing a file to set the directory as the current directory. All of the images will be loaded into the thumbnail cache (if enabled).
Once in the main PQV window. The current image is displayed with the default view option (see Settings). To change the zoom level, press the up and down buttons. To pan around the image, press and drag the stylus across the main window. Tap and hold in the main window to see a context menu with more options (alt-click on HPCs). These options include the ability to email, beam (via IR), and delete images.
The current view can be rotated in 90 degree increments; this rotation does not affect the image data, only the display. The source image data can also be rotated in 90 degree increments with the "Rotate Image" functions. For 1bpp (bilevel) images, rotating the view rotates the source image data.
PQV currently supports four types of animated files: AVI, QuickTime (MOV), GIF and FLI/FLC.
Open the animated file as you would a normal image file. The first 'page'
of the animation will be displayed in the main window. To start/stop the
animation, press the 'Play' toolbar icon (fourth from the left on the first
toolbar). While animations are running, the zoom and pan controls will
continue to function normally (when direct screen access is disabled). The animation rate can be controlled in the
Settings dialog. Animated files will appear to behave like multipage
files, but with limitations. The page navigation functions will only allow
going to page 1 and going to the next page on some types of animated files. Because of the nature of
some animated files, the previous page cannot be accessed. Some animated files
are also restricted from being edited; a change to a page will effect the next
pages in the sequence.
How to Configure File Associations
PQV allows you to configure file associations. File associations are the way that Windows matches file types to applications. Windows uses the file extension (e.g. .JPG) to associate files with applications. PQV allows you to configure up to twelve different file extensions be associated with it. An example of when this would be used is in the File Explorer; if you click on a filename within File Explorer, Windows will try to open the application associated with that file. When you click on the file associations icon (it looks like three cascaded pages), a dialog will open allowing you to choose which files to associate with PQV. The first time PQV is run, it saves the current file associations for possible restoration. The dialog will display current associations with a check next to the extension name. To restore the previous file association simply uncheck the box.
PQV includes two ways to work with thumbnail images: A line of thumbnails may be displayed at the bottom of the main window by turning on the "Combo View", also an entire window of thumbnail images can be displayed by pressing the "thumbnail" toolbar icon or selecting "thumbnail view" from the Options menu. The thumbnail size and shape can be controlled from the Settings dialog.
Combo View
In the combo view, a horizontal scroll bar will be displayed along the
bottom of the window. You can rapidly scan the thumbnails with the scroll
bar. To view a specific thumbnail image, click on it. Tap-n-hold
over a thumbnail image to display its filename.
The current thumbnail image can also be used to pan around the image.
Select an image, zoom in so that the entire image does not fit on the display
and you will see a white and blue box appear in the thumbnail image. Click
and move this box to pan around the image.
The Thumbnail Window
The purpose of this window is to facilitate rapid access to multiple images
at a time. Images can be selected individually and copied, deleted,
rotated and so forth. Once in the
thumbnail window, pressing the up and down buttons will navigate between images.
Pressing the left button will toggle back to the main PQV window and pressing
the Action (Enter) button (or a single-click) will open the current image. Press and hold the
stylus (Alt-click for HPC) over a thumbnail image to see a context menu with
more options. These options include the ability to email, beam (via IR),
delete images.
PQV includes a slide show feature to show off your favorite images. This feature is only available for Pocket PCs and some HPC devices. Begin by clicking on the slideshow icon (first icon of fourth toolbar). PQV will immediately begin displaying your images in the current sort sequence from the current directory (starting with the current image). The order can also be set to random to make it more interesting. The transition effect and speed can be controlled from the Settings dialog. Tap anywhere on the display or press the Action (Enter) button to end the slide show. Voice notes can optionally be played as well. Press the right/up button to manually advance to the next slide and the left/down button to go to the previous slide.
PQV includes the ability to send an image as an email attachment. This feature includes options for reducing the image size and converting the image to another format. In the case of sending images from a digital camera, it can prove useful to reduce the size since sending a full resolution image may not be very practical depending on the image size and your internet connection speed. e.g. a 3.3 Megapixel image captured from a camera may be larger than 1 megabyte.
How to Use the Settings / Preferences
PQV allows control over many aspects of its operation. The Settings are accessed from the context menu or by clicking on the second icon in the fourth toolbar. The settings are divided into the following 10 sections:
Preferences
Default View - The default view is used when
opening image files
Background Color - The color used to paint the
unused spaces in windows
Animation Rate - Controls the rate of animation for
GIF and FLI/FLC files
Use scale-to-gray for 1bpp images - Uses a
technique to make bilevel images look better at small zoom ratios
Auto-rotate images for best fit - Automatically
rotate the images +/- 90 degrees when their shape does not match the display
orientation. The rotation direction also affects auto-rotation in
fullscreen mode.
Optimize colors for display - Uses a image
dithering algorithm to make images appear better on 12, 8 and 4-bit displays
Ignore non-fatal errors - Allows images with
corrupted data to be viewed
Auto Size/Rotate Fullscreen Mode - This option will size and rotate
images to best fit the display while in fullscreen mode
Pre-quality files - This option will force file
lists to only display supported image files even when "all files" is selected
Quickview mode opens fullscreen - This option will
force PQV to open in fullscreen mode when launched from a file association (e.g.
tapping a JPG file in File Explorer)
Smooth scaling - The normal scaling feature
discards pixels to shrink an image. This option (slower) will produce much
higher quality views when shrinking images to fit the display by averaging the
pixels together.
Capture
Root file name - This name will get a number and
file extension appended to it for form the screen capture filename. e.g.
cap --> cap0001.bmp
Destination Directory - Where screen capture files
are stored
File Format - Captured files will be stored in this
format. Note that GIF does not support more than 8 bits per pixel, so the
bit depth with be adjusted automatically to accommodate the format
Delay - This delay takes place after the screen
capture icon is clicked. This allows one to switch applications and
prepare the screen to be captured
Save 16-bpp images as 24-bpp - The prevent loss of
color information, use this option to ensure that 16-bpp images don't get
converted to 8-bpp
Reset file counter - This counter will
automatically increment after each screen shot is taken
Slide Show
Transition Effect - The effect used to transition
one image to the next
Transition Speed - The speed to display the
transitions; slow, medium and fast
Delay - The delay between each image
Timed / Manual - Controls how a slideshow
progresses. In timed mode, each slide is shown after the given delay; in
manual mode, the next/previous slides must be manually changed with the arrow
keys.
Loop Slideshow - Continuously loop through all of
the names in the directory
Random Order - Check this option for showing slides
in a random order as opposed to the current sorted order
Rotate for best fit - Rotate the images 90 degrees
clockwise to best fit the display
Play Sounds - This option will play wave files
associated with each image. The wave file name is <imagefilename>+".wav"
(e.g. IMG_1234.JPG.wav)
Wait for sounds to finish - This will cause the
slideshow to pause on an image until the sound has completed
Show Filename - Display the filename above each
image
Stretch to Fill - Use this option to ensure there
are no empty areas of the slide by zooming in to the image so that it fills the
display completely
Output to VGA - This option will send the slideshow
output to a Voyager VGA adapter
JPEG
JPEG Save Quality - Four quality levels for saving
JPEG images. The lower the quality level, the higher the compression
ratio. Typical color images compress 40:1 at low, 20:1 at medium and 8:1
at highest
Subsample (4:2:2) - Use this option to save 33% in
the output file size by subsampling the color space 2:1 in the vertical and
horizontal directions
Load 24-Bpp JPEGs as 16-Bpp - Since most CE
displays are 16-bits, this option allows JPEG images to load faster and save
memory for image detail which can't be seen anyway
Optimize JPEG load size - This option will attempt
to load JPEG images at reduced resolution to fit the display; e.g. a 1024x768
image will get loaded at 1/4 size for a Pocket PC display
Load JPEG images - manual control of how JPEG
images are loaded: full size, 1/4 size, 1/64 size and thumbnail. Thumbnail
will use the embedded thumbnail from the EXIF header if present.
Toolbars
Toolbar Icons - This list contains the available
functions to place in the toolbars. Currently there are over 70 functions
to choose from. Use the 'Add' button to add an icon to a toolbar
Current Toolbar - PQV allows 10 toolbars;
this list contains the current toolbar you are editing. The order that the
toolbar icons are listed is the order they will appear on the display
(top-to-bottom --> left-to-right). On top of this list will be displayed
the current toolbar name. Toolbar icons can be used multiple times in multiple
toolbars. Use the up and down buttons to change the order of icons.
Toolbar - This spin control selects from the
10 toolbars.
Reset - Resets all toolbars and names to their default
values.
Video
Play continuously - When checked, video playback will repeat indefinitely
Direct Screen Access - On supported devices, direct
screen access results in much faster video playback
Play Audio - Plays the audio part of AVI or
QuickTime videos when available
Orientation - Displays the video at normal or
rotated orientation. For 320x240 videos, rotation is needed for them to
fit on a Pocket PC display.
Size - The video may be played back at reduced
size. Reducing the size will increase the frame rate of playback since
less memory is used to play the video
GUI
Zoom Win Size - controls of the size of the zoom
window (in pixels)
Thumbnail Size - Controls the size of thumbnail images
Thumbnail Shape - Controls the shape of thumbnail
images (square, portrait, landscape)
Icon Bar - This option enables the icon bar (toolbar)
Menu Bar - This option enables the menu bar
Use stylus for area selection - Normally, the
stylus will allow the image to be panned. When checked, the stylus will
create a selection rectangle for use with the crop, copy and redeye functions.
Show names thumbnail view - Controls whether filenames are displayed in
the fullscreen thumbnail view
Cache thumbnails - This option is very
important because it controls if thumbnail images are enabled or disabled.
When not checked, no thumbnail images are available from the
Combo view, nor
the fullscreen view. When checked, thumbnail images are cached in the
background when the program starts and when a directory is selected
Buttons
For each button on your device, any function can be assigned.
Select the button from the top list, then select its function from the drop-down
list. There are 3 sets of button assignments; one for each operating mode.
For CE machines which are not recognized, the buttons will not have a
recognizable name or icon. In this case it will be necessary to press the
"Find Button" button to determine which button is which. After pressing
the "Find Button" button, press the button you wish to use; it will then be
selected in the list. Press the "Defaults" button to reset the button
assignments to their default values for the selected operating mode. The
app buttons can optionally be disabled to not interfere with their normal
functioning.
Gamma
Different devices have different display properties. The response
curve of a monitor is called its Gamma and is a typically non-linear. Some
Pocket PC displays are notoriously dark (e.g. iPAQ 38xx). This control
allows you to correct for the Gamma / brightness of a display. If an image
is currently loaded, it will be displayed below, otherwise a grayscale image
will be displayed. Slide the gamma and brightness controls until the image
looks good. Preset the reset button to reset the values to neutral.
Batch
Destination Directory - Where the
copied/converted/resized images will go
Log File - An option ASCII file which logs all of the batch activities
including errors
File Format - The destination file format and compression type when
converting files
Color Reduction - The method to use when the color bit depth needs to be
reduced (e.g. going from JPEG to GIF)
Scale Image - Option to resize an image based on a
fraction of its original size
Resize To: - Option to resize an image to an
explicitly specified width and height
Overwrite files of the same name - When this option
is not checked, files will not be overwritten and will generate an error in the
log
Editing
PQV includes simple image manipulation features and the ability to save
images in a variety of formats. The following image manipulations are
available:
Since PQV is not a paint program, each of these operations does not have an undo feature.
Modify Color Depth
PQV includes a unique function which allows one to convert an image from
any pixel bit depth to any other. For example, if you want to save a photo
as a FAX file, PQV allows you to convert a 24 or 16-bpp image to 1-bpp.
When reducing the bit depth of an image, there are two options: Best Color
Choices and Error Diffusion. Best Color Choices will simply choose the
closest color match within the limits of the new bit depth. Error
Diffusion uses a filtering technique to lessen the 'banding' effect color
reduction. This method uses patterns of dots to give the illusion of more
colors. Using this technique will create images which don't compress well.
Saving
PQV allows one to save the currently loaded page in a variety of formats.
Press the save icon (second icon on first toolbar) and a file selector dialog
will appear. Choose the destination directory, name and format and PQV
will save the current page. It is up to the user to specify the entire
filename including name extension. e.g. A JPEG file can be saved with an
extension of .gif.
NOTE: Certain file formats do not support all pixel bit depths. For example, it is not possible to save a 24-bpp image as a TIFF G4 file. The G4 compression method only supports bilevel (1-bpp) images. For this reason you may see an error message when trying to save images. Use the color modification function to convert the image to a different pixel depth.
PQV includes a powerful screen capture feature. This feature does not rely on GAPI, but uses another direct screen access method. With PQV it is possible to capture screens from programs which other screen capture utilities cannot.
There are two ways to capture screens: after a time delay and by pressing a 'App' button. From within PQV, after you have selected the name, delay and file format of screen captures on the settings page, click on the screen capture icon or select "Screen Capture" from the OPTIONS menu. During the preset delay, switch to the program you wish to capture and then wait for the delay to pass. If the program being captured is not using audio, you will hear a camera shutter sound. The file will be saved according to the settings and the numeric name will be automatically incremented. The second method of capturing screens is to assign one of the App buttons of your device to launch the PQV screen capture tool. Go to the first of the Pocket PC's settings pages and click on "Buttons". Choose an app button to assign and in the list of available programs to assign, it will be called "PQVSCL". Press the App button to activate the screen capture. Since many programs take control of the App buttons, the delay option was provided.
PQV includes a powerful image navigation tool called the Zoom Window. Suppose you are viewing a large image, and are examining details at a close-in zoom level, but would like to pan around the image. The Zoom Window allows you to see the entire image in a small window while not blocking your view of the image details. To activate the Zoom Window, click the middle icon on the fourth toolbar. This will toggle the Zoom Window on and off. The size of the Zoom Window can be adjusted in the Settings dialog. This same functionality is present in the thumbnail images at the bottom of the display when in the "Combo View".
PQV allows a portion of the current page to be copied to the Windows clipboard. Use the selection mode from the GUI settings page and then tap and drag a box around the area you wish to copy. Tap and hold the stylus to display the context menu item "Copy" or click on the Copy toolbar icon. The area will then be copied to the clipboard. This function copies the image at its real size. In other words, if you are viewing a 1024x768 image at 25% zoom and select the entire image to be copied to the clipboard, a 1024x768 image will be copied to the clipboard regardless of the zoom level. The images will be placed into the clipboard as Device Independent Bitmaps (CF_DIB) and can be used by any program which supports pasting bitmaps from the clipboard.
PQV allows you to use the entire displayable area of your CE device for viewing images. Fullscreen mode can be toggled by pressing the Action (Enter) button. In Fullscreen mode, the up and down keys control the zoom level and the image can be panned with the stylus. The left and right buttons can be used to select the previous and next image from the current directory.
How to Work with Multi-Page Files
PQV supports several different multipage file formats. Located in the middle of the first toolbar are three icons for working with multi-page files: previous page, go to page and next page. The 'go to page' icon also displays the current page number. Clicking on the 'go to page' icon will open a dialog box which displays the current page, the total number of pages and the desired destination page.
NOTE: Animation files are a special case of multi-page files and will only allow you to navigate to the next page and the first page. These currently include GIF and FLI/FLC files.
PQV's toolbar interface can be completely customized. There are multiple toolbars and each toolbar can be as large as the width of the display. There are over 40 functions to choose from which can be used in any way you wish. For example, you can define each toolbar to contain a help and exit button. The toolbar is edited from the preferences dialog. If you accidentally create a set of toolbars which does not include the preferences function, it can be accessed from the context menu on the main window (tap-and-hold). Click this link for more details.
PQV includes the ability to print bilevel images to IRDA or serially connected printers. The print logic creates PCL5 compatible output. This has only been tested on HP printers, but may work on other brands which support PCL. Currently printing is only support for bilevel images because of the memory and speed limitations of the Pocket PC. The print settings are as follows:
Port
Select either IRDA or a COM port
Resolution
The destination print resolution. Most printers supports resolutions which
are multiples of 150 or 180 dots per inch. It is possible, for example, to
print at 300 dpi to a 1200 dpi printer. If the source image is <= 300 dpi,
then it makes no sense to send the data at a higher resolution since it will
just take more time to print.
Page Range
Select to print all pages (default), the currently viewed page or a specific
range of pages.
Print Size
Fit To Page - Use this option to stretch or
shrink the page (symmetrically) to cover the maximum print area on a 8.5 x 11
inch page.
Actual Size - This option attempts to create N
inches of printed output for every N inches of image. It is only available
when resolution information is present in the image.
One to One - This option will create 1 printer
pixel for every document pixel (no scaling).
Orientation
Portrait and Landscape orientations are available.
PQV's directory navigation tool borrows some features from the built-in File
Explorer. The current directory is displayed at the top. Clicking on
the directory name will drop down a list of the directory levels above it. The
subdirectories present in the current directory are displayed in the listview
below. Clicking on a directory name will set the current directory.
Clicking on the NEW button will create a new directory and set the list into
"rename" mode. To rename a directory, tap the directory name and while
holding down the stylus, move away from that name. The name will remain
highlighted and you can then click the RENAME button.
How to Add / Edit Images in a Custom Slide Show
To create a custom slideshow, each image must be individually added.
When viewing an image in the main window or from the thumbnail window, an image
can be added to the slideshow. A slide add/edit dialog box will be
displayed showing a miniature view of how the image will look during the
slideshow. Each of the following slideshow options will affect only the
specific slide and not the other slides.
Image File - The name of the current image file; it
cannot be changed here.
Audio File - The name of the current audio file.
This is generated automatically from the image file name (extension changed to
.WAV), but can be changed from within this window.
Rotate 90 - The view angle of the slide can be
changed in 90 degree increments.
Stretch to Fill - The image will be zoomed in so
that the entire display area is covered. The preview image will show how
it will appear during the slideshow.
Delay - The time that the slide will remain in view
(in milliseconds).
Transition - The transition effect used to go from
this image to the next.
How to Manage a Custom Slide Show
This window allows you to manage the operation of a custom slideshow.
Use the UP and DOWN buttons to change the order of slides by moving them in the
list. Individual slides can be DELETED, EDITED or the entire set of slides
can be removed. After making changes to the slideshow (either adding,
deleting, or changing), you will be prompted to save the changes before exiting
the program.
