2D mipmap generator

Generate mipmaps for 2D images.

Synopsis

./MipmapGen2D [-f format -s brickSize] imageFilename maxLevel

./MipmapGen2D [-f format -s brickSize] inputBatchFilename maxLevel [outputBatchFilename]

Description

Generate mipmaps for an image:

Generate mipmaps for an image specified by imageFilename, from level 0 (the original image size) to the level specified by maxLevel. If the maxLevel is -1, ./MipmapGen2D generates all the mipmaps from the original image size to the biggest size smaller than the brickSize.

Generate mipmaps for a set of images:

Generate mipmaps for a set of images listed in the inputBatchFilename, all from level 0 (the original image size) to the level specified by maxLevel.

If outputBatchFilename is specified, ./MipmapGen2D assumes the image set is an animation, and generates a single text file which lists mipmaps for each frame and timestamps. If outputBatchFilename is not specified, it’s the same as a batch mipmaps generation. ./MipmapGen2D generates mipmaps and a text file for each image in the set, as if they are generated separately.
