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.
- OPTIONS
- -f format
- Specify file format for the output mipmaps. Default is mix.
- sep: Save all pixels of a channel together, i.e. RRR…R, GGG…G, BBB…B
- mix: Save channels of one pixel together, i.e. RGB, RGB, RGB…RGB
- -s brickSize
- Specify the brick size. Default is 128.
