iPaq screen format and GameAPI


iPaq screen format and GameAPI

Postby Hunter » Apr 24, 2001 @ 3:32am

The iPaq has a 4096 colour display (4 bits each of Red, Green, and Blue). Yet my application which uses GameAPI reports a pixel format of 565. All the drawing code goes through my 565 pixel plotting code, and is correctly drawn to the screen. Why is this? If the video driver is doing some internal conversion, it seems a waste of time when it could have reported the native 444 format in the first place.<br><br>Any ideas?

Yes, the drivers support RGB 565. I would say this is at the hardware level, as I remember hearing that the Sony display has 16 bit color data bus width. So no conversion is being done by software. That is the standard encoding for Pocket PC devices, which all use 565 at this time to my knowledge.<br><br>Dan East
