NAME¶

vga_guesstiming - calculate a timing line for the given resolution

SYNOPSIS¶

#include <vga.h> int vga_guesstiming(int x, int y, int clue, int arg);

DESCRIPTION¶

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.

BUGS¶

No guarantee that a modeline will be created, or that a created modeline will be usefull is given.
