4.8.1.9.10.7 Image Fields
– Field Type 5
An Image Field displays an image that has been uploaded to the DX-2200-TI-03. Image Fields can be used
to display a logo or other custom graphics. The DX-2200 Uploader software supplied with the product is
used to upload images and store them in flash memory. Refer to
§5 DX2200 Software Upload Utility DX-
2200 Software Upload Utility for information about uploading images.
The image is displayed at the position specified by coordinate A of the Graphic Field. Any part of the image
extending beyond the size of the overlay is not displayed.
Uploaded images may have transparency for some or all pixels in the image. Support for transparency
depends on the file format of the image. Images that do not include transparency are always uploaded with
all pixels fully visible. By default, images will be displayed with the transparency that was included in the
uploaded image. The GnnAaaa command can be used to make the image more transparent. It is not
possible to make an image less transparent than was defined in the original file.
When an image is fully transparent or partly transparent, the image frame background will be visible behind
the image. The background color is set by the GnnBRrrr, GnnBggg, GnnBBbbb commands, and the
background transparency is set by the GnnBAaaa command. When the image frame background has
transparency, lower layers in the video mix will be visible behind the image. The default background
transparency for a graphic field is 255 (fully transparent). The image frame background will not be visible
unless the default transparency is changed.
