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
SnnBRrrr, SnnBggg, SnnBBbbb commands, and the background transparency is
set by the SnnBAaaa command. When the image frame background has full or
partial 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.
Images are specified by an ID number that is set when the image is uploaded to
the product. If the requested image is not found in memory, then the Graphic Field
has no effect.
Images are loaded from flash into main memory the first time they are required for
a layer update. The first layer update using an image will be significantly slower
than subsequent updates.

Rectangle XYWH
– Field Type 6
This rectangle field type is the same as field type 2 with the exception that it is
specified by top/left corner and width/height instead of top/left corner and
bottom/right corner. In some applications it may be more convenient or efficient to
specify the rectangle with width and height.
The SnnPBxxxx,yyyy is used to specify the width and height of the rectangle. All
other commands are the same as for field type 2 rectangles.
Rectangle Field Display Example
S6PA800,300
' top left corner at 800, 300
S6PB200,400
' width 200 pixels, height 400 pixels
S6M6
' type = Rectangle Field XYWH
S6S
' enable display of field 6 and update
