Pull-Down Menus, Controls, Commands | Digital Spectrum 1862-MF-61-7

insert images into the Digital PixMaster™ template, or select images from any application, directory, CD, DVD, etc. to import via “drag and drop” or “copy/paste” into the template. When images are transferred into the Digital PixMaster template the image is automatically resized accordingly. The original source image is left unaltered.

Repeat this process until all of the desired images are in the template. The figure below shows an example of a Digital PixMaster™ slideshow after images have been imported via “drag and drop” from other applications and directories.

Below each image is the slide number, the time duration the image will be displayed, and whether or not a transition effect has been selected for that image.

6.6Pull-Down Menus, Controls, Commands

Across the top of the Digital PixMaster application are the pull-down menus: File, Edit, View, Digital Frame, and Help. All of the commands (except those in the Digital Frame pull-down) can be performed on the PC without the need for a MemoryFrame to be connected. This allows you to create slideshows anytime. Table 1 below shows the various options under the File, Edit, and View pull-down menus.

File		Edit		View	Digital Frame
New	Ctrl-N	Undo	Ctrl-Z	Preview Slideshow	Send Slideshow
Open…	Ctrl-O	Redo	Ctrl-Y	Status Bar	Retrieve Slideshow
Close	Ctrl-F4	Cut	Ctrl-X	Toolbar	Update Firmware
Save	Ctrl-S	Copy	Ctrl-C	Slide Properties	Properties
Save As…		Paste	Ctrl-V	Switch View
Preferences…		Delete	Del
Recent Files		Select All	Ctrl-A
Exit	Alt-F4	Insert	Ctrl-I

6.7Naming and Saving Slideshows

Create, name, and save different slideshows using naming conventions of your choice. To save a slideshow, click on File then select “Save” or “Save As” to save the slideshow. The file extension for MemoryFrame slideshows created with Digital PixMaster is “.pd2” extension. Digital PixMaster can have only one slideshow open at one time. If you choose to open a new blank slideshow while another is already open, the program will close the first one (asking you if you want to save first) before opening the new blank one.

•Image Decompression takes about 5 seconds

•Scaling an image can take another 10 seconds

•Rotating images takes the same time as scaling images. Even if 600x800 to begin with, preparing a portrait image adds another 10 seconds

•Background tasks that occur immediately after power-on place a drain on performance until they complete

To help homogenize the performance of the MemoryFrame, images are cached for display. If an imager is available in the cache, it can be displayed immediately. The key to a fast slideshow is understanding how to keep the cache full.

With a best case of 5 seconds per image to decompress, it becomes clear than it is nearly impossible to achieve the 1 second minimal duration that is allowed. However, strategically placing "pause" slides will allow the cache to become populated.

Here are some tips on how to optimize performance:

•Do not have more than 2-3 consecutive slides with "minimum" durations

•Avoid long stretches of slides with durations of 5 or fewer seconds

•Throw in "pause" slides with content that the viewer will need time to study -- this will allow the cache engine to catch up

•If using odd-sized images, particularly those between 4:3 or 3:4 and square, pre-scale them before inserting them into Digital PixMaster.

•Make sure that images are no larger than 800 pixels wide and 600 pixels tall or, if using Portrait Mode, 600 pixels wide and 800 pixels tall

•Use transition effects between slides -- transition effects add activity to the slideshow and provide extra time for image preparation

12.2Steps to Create 16:9 Content for MemoryFrame (Landscape)

The MemoryFrame is designed to show 4:3 aspect on the internal display. The VGA Out interface of the MemoryFrame allows simultaneous display to large format monitors. These may be a large 16:9 aspect display such as a plasma monitor or HDTV monitor. By following the steps below, images can be composed so that they appear correctly on a 16:9 display.
