Hardware Cursor/Ink Layer
SED1355
X23A-B-006-03
Note
1355BMP requires the BMP images for the Hardware Cursor and the Ink Layer to be stored in
specific formats. The Hardware Cursor BMP image must have a color depth of four bit-per-pixel and
be 64x64 pixels in resolution. The Ink Layer BMP image must have a color depth of four bit-per-
pixel and be the same resolution as the displayed image.
Both images are stored at a color depth of four bit-per-pixel allowing easy editing and saving in most
paint programs. To allow the two bit-per-pixel Hardware Cursor and Ink Layer to use the four bit-
per-pixel images, they are translated to two bit-per-pixel as in the following table.
1355BMP will automatically finish execution and return to the prompt.
