Enclosing class:

Image

public static class Image.Lossless
extends Image

A lossless image (similar to PNG). There are 3 formats - 8, 16 and 32 bit. For 8 and 16 bit images there is a color table and the image data consists of either an 8 or 16 bit index into the table for each pixel. 32 bit images have no color table - each pixel consists of 4 bytes: (alpha,red,green,blue). If there is no alpha then the first byte will be 255. For all formats, the length of each row of pixel data must be a multiple of 32 bits. If the actual row data is smaller then it should be padded up to next multiple of 32 bits.
