Where does this number 678 come from to achieve a PAL 16:9 aspect ratio screen? I want to write similar code for NTSC.
#define VI_MAX_WIDTH_PAL 720 #define VI_MAX_HEIGHT_PAL 574
- The 678 number was found by experimentation with my Widescreen LCD TV - 678 stretches the 640 pixel wide framebuffer to just touch the edge of my screen. Other people's TVs may vary. It doesn't have anything to do with a 16:9 aspect ratio, you still need to use the GX matrices to squash a 16:9 view into a 4:3 framebuffer. --Pepsiman 14:37, 7 August 2008 (CEST)
