Bitmap capture
Bitmap data is returned in the BUFFER structure. The following options are available:
§ bitmap flip: controls the order of lines - “natural” order (top line first), or Windows order (bottom
line first);
§ bitmap color format: monochrome (1 byte/pixel), RGB (3 bytes/pixel), YCrCb (2 bytes/pixel);
§ bitmap size: large (256x192), small (128x96).
All bitmap capture options cannot be changed on a frame-to-frame basis.
Text caption
Text caption data is set up in the COMMAND structure. Caption size is 64 characters. Caption can be
turned on or off on a frame-to-frame basis. The following options are available:
§ caption window format: 8x8, 16x4, or 32x2 characters. Cannot be changed on a frame-to-frame
basis.
§ caption window position: one of the 4 corners of the image. Cannot be changed on a frame-to-
frame basis.
§ caption font size: small (8x16 pixels), large (16x32 pixels). Cannot be changed on a frame-to-
frame basis.
§ caption characters color: one of 8 predefined colors (see Software Reference for details). Can be
changed on a frame-to-frame basis.
Text caption is transparent (i.e. only the characters overlay the image). The caption is overlayed on
the JPEG image only. As long as the caption is overlayed before the compression, usual quality
degradation resulting from compression affects the caption.
