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 |
|---|---|---|---|---|
EmulatedBltAlphaText02 |
Special-case fast blit function for rendering antialiased text. This function assumes a mask surface containing the 4-bits per pixel (bpp) alpha bitmap for the symbol. |
