WebA common operation that reduces the size of large 24 bit bitmaps is to convert them to indexed colour with an optimised palette, that is, a palette which best represents the colours available in the bitmap. 4 bit indexed colour. This is identical to 8 bit colour except now only half a byte, 4 bits are used for the index. WebImage Data Compression is of two types, lossless or lossy. ... Or a 3-bit index is 2 3 = 8 values of 0..7, which indexes into an 8 color palette. The actual pixel data is this index number into that limited palette of colors.
