ivec3 textureSize(gsampler2DMSArray sampler);

PARAMETERS¶

sampler

lod

DESCRIPTION¶

textureSize returns the dimensions of level lod (if present) of the texture bound to sampler. The components in the return value are filled in, in order, with the width, height and depth of the texture. For the array forms, the last component of the return value is the number of layers in the texture array.
