Image Specifications
Media files used on the UDC-8625A series card must meet the specifications outlined in
Table 7.1 . Note that if larger images are used, the images will be clipped to the dimensions listed
in Table 7.1 .
File Naming Specifications
The name can contain letters, numbers, and spaces, but cannot contain symbols such as ! @ # & *
( ) ? / , ‘ “.
If you are naming an animation, each file must be numbered in the sequence that it will play out.
The following restrictions apply to file names for animations:
• The file names must be suffixed with an underscore followed by three or more digits,
then the period (.), and then the file type suffix.
• Each file in the sequence must have the same numbering scheme, and numbering must be
continuous.
• The UDC-8625A series card loads files in numerical order.
The following is an example of a 10-frame animation using a typical numbering scheme:
• DTVB_000.tga
• DTVB_001.tga
• ...
• DTVB_009.tga
