hi again; after I have send the previous mail about vga_drawscansegment(), I saw that it was totaly wrong ! I am sorry about that, but I have no net connection at home, so I couldnt mail again. Anyway I corrected that. And thanks for reply. >I think it usually does not make sense to use those functions to draw >one pixel at a time as they have too much overhead. I wanted to draw one pixel at a time, to draw only the changed pixel. while (i < bufsize) { if (memcmp(oldbuf + i, newbuf + i, BYTEPERPIXEL) { memcpy(oldbuf + i, newbuf + i, BYTESPERPIXEL); draw_the_changed_pixel(); } i+=BYTESPERPIXEL; } But I couldnt choose a function for that; vga_drawscansegment() or gl_putboxpart() ? which one is faster, and needs less resource? Again sorry for the prev mail. Alper. _________________________________________________________________ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus ------------------------------------------------------------------ Unsubscribe: To: listbot@svgalib.org Body: unsubscribe linux-svgalib
