Blt Flags

Const SRCAND = &H8800C6
Const SRCCOPY = &HCC0020
Const SRCERASE = &H440328
Const SRCINVERT = &H660046
Const SRCPAINT = &HEE0086

The Blt flags tell the Bltting functions what method to use when transfering a piece of an image from the source to the target device. Exactly one flag must be used -- they cannot be combined. The Ands, Ors, etc. are binary operations performed on a pixel-by-pixel basis with the colors in the source and target. The result is the color that appears.

SRCAND
destination = image And destination
SRCCOPY
destination = image
SRCERASE
destination = image And (Not destination)
SRCINVERT
destination = image Xor destination
SRCPAINT
destination = image Or destination
