vga_guesstiming3vga
Calculate a timing line for the given resolution
Usage
#include <vga.h>
int vga_guesstiming(int x, int y, int clue, int arg);
Overview
Calculates a timing line for a x*y resolution, according to the value of clue.
Calculation methods
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.
