GIF File Compression
The Graphic Interchange Format file format utilizes a relatively basic form of file compression which squeezes out inefficiencies within the data storage without lose data or distorting the image. The LZW compression scheme is finest at compressing images along with large fields of homogeneous colour. LZW is the compression scheme utilized in Graphic Interchange Format. This is less efficient at compressing complicated pictures along with many colours and complicated textures as demonstrated below with the assist of two graphics.
Consequently some methods are utilized to handle this huge information and these methods are termed as animation process that are classified as: First Method: In this method,
