FUNCTION
Blits from source BitMap to position specified in destination RastPort using minterm.
INPUTS
- srcbm
-
a pointer to the source bitmap
- srcx
-
x offset into source bitmap
- srcy
-
y offset into source bitmap
- destrp
-
a pointer to the destination rastport
- destX
-
x offset into dest rastport
- destY
-
y offset into dest rastport
- sizeX
-
width of blit in pixels
- sizeY
-
height of blit in rows
- minterm
-
minterm to use for this blit
RESULT
This function always returns TRUE, starting with Kickstart 1.2 (V33).
Prior releases could run out of memory when handling overlapping blit operations and, if this occured, would return FALSE to indicate failure.
