Gets the number of mipmap levels in the CompressedImageData. The base mipmap level (original image) is included in the count.
mipmaps = CompressedImageData:getMipmapCount( )
- The number of mipmap levels stored in the CompressedImageData.
Mipmap filtering cannot be activated for an Image created from a CompressedImageData which does not have enough mipmap levels to go down to 1x1. For example, a 256x256 image created from a CompressedImageData should have 8 mipmap levels or Image:setMipmapFilter will error. Most tools which can create compressed textures are able to automatically generate mipmaps for them in the same file.
