3.1.4 Solid Fill Setup
3.1.5 Color BLT Setup
Table 2: Mono Bitmap & Text Data Parameters
When the BltCtl.SRC register is set for font rendering (3), the Engine automatically
accommodates the predefined padding and alignment requirements for fonts. This
means that the host data will be tightly packed with no padding between scanlines or
before the very first pixel. After the first font glyph has been sent from the host, only
two registers will need to be re-loaded to initiate the next text BLT: DstXY/DstLinear
and BltSize.
Solid fill is a common graphics operation. To achieve low programming overhead, the
drawing engine only uses five parameters to set up a solid color fill.
Table 3: Solid Color Fill Parameters
The Engine uses up to 10 parameters to set up a color BLT.

Description
Specifies the drawing destination on the screen.
Specifies the location of source data for screen-to-screen BLTs. Specifies
start of line alignment for host-to-screen operations.
Specifies the number of pixels between scanlines in the source for screen-
to-screen BLTs. Unused for host-to-screen BLTs.
Specifies the number of pixels between scanlines in the destination.
Specifies the drawing color for solid fill BLTs using block write. Also may be
used to load the PatRam quickly.
The background color register may be used to help load the PatRam
quickly.
The Color Compare Color may be loaded if transparency is enabled in the
BltCtl register.
