  • Article

The emulation library includes many functions, and you can add your own. The source code is located in %_WINCEROOT%\Public\Common\Oak\Drivers\Display\Emul.

Function Description Raster operation (ROP) Source bit depth Target bit depth

EmulatedBltAlphaText08 Special-case fast blit function for rendering antialiased text. This function assumes a mask surface containing the 4-bpp alpha bitmap for the symbol and an 8-bpp target surface that is in 32-bit RGB mode. AAF0 – 08 (332 mode only)
EmulatedBltAlphaText16 Special-case fast blit function for rendering antialiased text. Assumes mask surface containing the 4-bpp alpha bitmap for the symbol. AAF0 – 16
