Blit flags
From FenixWiki
(Redirected from B SBLEND)
[edit] Definition
Blit flags are bit flags which can be passed to some map functions, to specify a certain effect when blitting a graphic. These functions are:
- xput()
- map_xput()
- map_xputnp()
They can also be used to specify a certain effect for the blitting of the graphic of a process, by assigning blit flags to its local variable flags.
In Fenix versions prior to 0.89c, the constants are not available and have to be declared or defined manually. Alternatively the values themselves can be used.
