I have java program that reads a jpegfile from the harddrive and uses it as the background image for various other things. The image itself is stored in a BufferImage

Jul 31, 2008 · Values typically range from 1 up to 8, then 24 and 32. 1bit gives you black and white only, with values up to 8bit giving up to 256 unique colors. 24bit is RGB and 32bit is CMYK (and you can add an optional alpha (transparency) channel to both of these for 32bit or 40bit images, although we won't cover that here). Step1: Generate the 8-bit color Look Up Table (LUT) by the Uniform Color Quantization and display the table to the console as shown below. Step2: Convert each 24-bit pixel of the input image into an 8-bit index value. Save the 8-bit color index values into [InputFileName]-index.ppm file. Assign the same index values to R, G, and B.
All components are represented in the colormap as 8-bit unsigned integral values. Some constructors allow the caller to specify "holes" in the colormap by indicating which colormap entries are valid and which represent unusable colors via the bits set in a BigInteger object.
ConvertUtil (image4j) public static java.awt.image.BufferedImage convert8(java.awt.image.BufferedImage src) Converts the source image to 8-bit colour using the default 256-colour palette. No transparency. Need to write 8 bit image using javax.imageio.I
