maximum resolution of image load by openGL

[mr_empty]

hi all,

  i want to load a very high resolution of image, say about 30000X40000, is that support by openGL?thanks!

Not to my knowledge I think the highest accepted by most cards is 4096x4096 (less for some), I guess it really depends what you want to do with it

Code Select Expand


GLint textureSize;
glGetIntegerv(GL_MAX_TEXTURE_SIZE, &textureSize);

The maximum I have seen is 8192x8192

Instead of displaying a huge image, why not divide it in chunks of 512x512 or 1024x1024?

GLUbuildmipmap will make things slower for that.
