How do you flip screenshots?

[Jonathan_NL]

Just wondering how you do it... I just 'invented' this:

Code Sample

char *row = malloc(width*3); for(y=0; y<height/2; y++) { memcpy(row, pix+y*width*3, width*3); memcpy(pix+y*width*3, pix+(height-y-1)*width*3, width*3); memcpy(pix+(height-y-1)*width*3, row, width*3); } free(row);

It can probably be done faster (after edit I'm not sure), but hey, it works, I made it in 3 seconds or so and it doesn't use much RAM. :-)

Another edit: you can also write the lines in opposite order of course. Not sure how fast that is...
