private $gifMaxWidth;GIF pictures store single raster image data or multiple raster image data in 8-bit color or 256 colors. GIF images support transparency, compression, interlacing and multi-image images (animated GIFs). GIF transparency is not alpha channel transparency and cannot support translucency effects. GIF compression is LZW compression, with a compression ratio of approximately 3:1. Animated GIFs are supported in the GIF89a version of the GIF file specification. Exquisite pictures are an indispensable element for making a website, especially GIF animations, which can make an originally dull website come to life. What you may see most is the constantly rotating “Welcome” and advertising banners of different styles. On the Windows platform, there are many tools for making GIF animations, among which the famous ones include Adobe's ImageReady, Ulead's GIF Animation, etc. On the Linux platform, we can also easily create dynamic GIF animations. GIMP in Linux is a GIF animation production tool that is as easy to use and powerful as GIF Animation or ImageReady. Not only is it fully capable of GIF animation production, but it can also make full use of GIMP's powerful image processing functions to make GIF animations more infectious and attractive.
