| Abstract | Graphics image files can be stored in different file formats. One of the most general form is bitmap image format. Bitmap file format is an uncompressed form of image consisting of matrix of pixel constructing the image. BMP (24bit) represents each pixel in set of 24 bits comprising of RGB(Red, Green, Blue). Where BMP(32bit) represents one additional byte of alpha for transparency/opaque. Researcher identified redundancy of colors and made model to compress BMP(24bit) file. A model is developed to list all unique color of the image and store only index of these unique color instead of the whole 3 RGB color. The compression performance is based on number of unique colors and width-height of the image. In this paper researcher has made an effort to extract such bit patterns representing the pixel and then using such different bit patterns determines the total number of colors represented in image. Once the number of color is found it is possible to compress the file by grouping similar colors with exact pixel positions. Paper is prepared based on the research to analyze the image file and then compressing it. The model demonstrated here for 24bit file and at last concluded with tradeoff, improvements and limitation. |
