System.drawing.bitmap write to file

Saves this Image to the specified file or stream. A string that contains the name of the file to which to save this Image. The ImageCodecInfo for this Image. An EncoderParameters to use for this Image. The following example creates a Bitmap object from a BMP file. The code saves the bitmap to three JPEG files, each with a different quality level. Saving the image to the same file it was constructed from is not allowed and throws an exception.

The Stream where the image will be saved. An EncoderParameters that specifies parameters used by the image encoder. Do not save an image to the same stream that was used to construct the image. Doing so might damage the stream. Here is my take just by looping through a list of colors to write, The down side is it takes 30 mins to do px image vs C less than a minute import System.
