View Full Version : screenshots on Linux
12-26-2003, 02:57 AM
Are there are any screenshot tools on Linux that help you to take shots while a demo/game is running?
The one with gimp isn't very convenient I think.

GNOME has a built in Screenshot feature.
I kinda like GIMPs screenshot feature. Timed screenshots work really well for me.

I use good ole `xwd` which can then be read by gimp to convert to your favorite format.

I always use import (ImageMagick cli tool).

If it's your own code, I have a small routine that will save a snapshot of any openGL window as a .bmp but you have to link it in, so we're not talking about taking a program that you are running and doing it... I build it into all my demos now though, so I can print any time I want.

sounds good, did you made it already available somewhere? Or do you wanna get dozens of e-mail requests? ;-)

I found this on the libSDL archive mailing list, maybe is the same routine dovkruger is talking about...
int Screenshot(char *filename)
unsigned char *pixels;
if (!(screen->flags & SDL_OPENGL))
temp = SDL_CreateRGBSurface(SDL_SWSURFACE, screen->w, screen->h, 24,
#if SDL_BYTEORDER == SDL_LIL_ENDIAN
0x000000FF, 0x0000FF00, 0x00FF0000, 0
0x00FF0000, 0x0000FF00, 0x000000FF, 0
if (temp == NULL)
pixels = malloc(3 * screen->w * screen->h);
if (pixels == NULL)
glReadPixels(0, 0, screen->w, screen->h, GL_RGB, GL_UNSIGNED_BYTE, pixels);
for (i=0; i<screen->h; i++)
memcpy(((char *) temp->pixels) + temp->pitch * i, pixels + 3*screen->w * (screen->h-i-1), screen->w*3);
