Conversion from BMP to GIF Format Based on Improved LZW
Pan Hong-xia · Mechanical Management and Development · 2010
The conversion from the BMP file into the GIF file in VC++ environment is discussed. These two kinds of image file format are analyzed first. Then, in the VC++ environment, its own function lib files are set up. On the basis of understanding the principle of the LZW coding, the improved algorithm in VC++ environment is realized. By applying the function lib file established above,the corresponding specific image data will be found. In this way, the BMP data can be inverted into GIF format through the improved LZW coding algorithm, which realizes the conversion of the image format.
