vga_guesstiming − calculate a timing line for the given resolution |
|
#include <vga.h> int vga_guesstiming(int x, int y, int clue, int arg); |
|
Calculates a timing line for a x*y resolution, according to the value of clue. |
|
If clue is 0, then the aspect ratio for the requested mode ( x:y ) must be 4:3. A mode with the same aspect ratio closest to the requested, while still having a higher resolution is found, and then scaled down to the requested mode. If clue is 1, then the aspect ratio for the requested mode ( x:y ) must be 4:3. A mode with the same aspect ratio closest to the requested, while still having a lower resolution is found, and then scaled down to the requested mode. |
|
No guarantee that a modeline will be created, or that a created modeline will be usefull is given. |
