| − | ;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.
| |
| − |
| |
| − | ;VERSION
| |
| − | :Current version only supports TIFF image. The input TIFF image should be uncompressed. Only the data chunk specified by the first image file directory (IFD) will be processed.
| |
| − |
| |
| − | ;FILE FORMAT
| |
| − | :#Mipmaps
| |
| − | :For each mipmap level of an image, we divide the output mipmap into fixed size bricks (Fig. 1), and save all the bricks of one mipmap level to one file.
