| texture - texture handle |
|
Returns the height of a texture, in pixels. The companion to TextureWidth: use the pair to size drawing operations to a texture you did not create yourself, or to work out the aspect ratio of a loaded image before you stretch a quad to match it. For a multi-frame texture made by LoadAnimTexture this is the height of one frame, not of the source image. See also: TextureWidth, TextureBuffer, CreateTexture, LoadTexture. |
