hi,
is there a limit to what max size an image can be so that pix_image can load it? i'm trying to load an 400M png. does this depend on memory on graphic card? where can i find what is the limit?
pix_image itself does not impose any limitations. however:
- the image is loaded into ram, so your uncompressed (RGBA!) image must
be small enough to fit into ram
- the image-loading backend might have a limitation (and it might use
more memory while loading the image than is required to store the uncompressed image); this might depend on the image-loading backend you are using (on linux this is usually imagemagick)
- your gfx-card will have problems texturing images that are bigger
than a hw-dependent size. you can query it by calling glGetFloat(GL_MAX_TEXTURE_SIZE), e.g.
[gemhead] | [GEMglGetFloatv GL_MAX_TEXTURE_SIZE] | (this will give the maximum texture-size in 1 dimension; here (GeForce 7800GTX) it gives me 4096, which means that the maximum texture it can handle is 4096x4096 pixels)
