A Local Color Map is optional and defined here for future use. If the 'M' bit of byte 10 of the Image Descriptor is set, then a color map follows the Image Descriptor that applies only to the following image. At the end of the image, the color map will revert to that defined after the Screen Descriptor. Note that the 'pixel' field of byte 10 of the Image Descriptor is used only if a Local Color Map is indicated. This defines the parameters not only for the image pixel size, but determines the number of color map entries that follow. The bits per pixel value will also revert to the value specified in the Screen Descriptor when processing of the image is complete. 1.gif is just data, how does it revert global color map? 2.if interlaced is set, will the gif data arrange at interlaced order? is interlace not implemented by code? it is by data?
