Arguments
None.

number mipmaps- The number of mipmap levels stored in the CompressedData.
Notes
Mipmap filtering cannot be activated for an Image created from a CompressedData which does not have enough mipmap levels to go down to 1x1. For example, a 256x256 image created from a CompressedData should have 8 mipmap levels or Image:setMipmapFilter will error.
