In LWJGL, is it possible to create SRGB framebuffers?

Yes. You need to check for the GL_ARB_framebuffer_sRGB extension and use new PixelFormat(...).withSRGB(true).

Thank you for the response, i've already tried withSRGB(true) but it seems not work. I have now checked the extension and its value is true, so i have the requisites...I'll re-check my code, if i don't find what is wrong i'll write here!

is PixelFormat().withSRGB(true) equals to this in FreeGLUT?

Code Select

unsigned int defaults(unsigned int displayMode, int &width, int &height)
{
    return displayMode | GLUT_SRGB;
}
