Abstract:
1. A method of creating a binary animation file comprising the steps of: selecting an initial image and subsequent images having pixels; converting a colour pallet of the initial image having n indexes to a colour pallet having n− determining, in addition to the initial image, a second and subsequent images which will be contained in the file and defining a frameset which begins with the initial image and defines a sequence of images; compressing the initial image using Run Length Encoding and storing it to a movie file; creating, using the mask index, a new data array for the second image and subsequent images; comparing a second image to the initial image on a pixel by pixel basis; storing differences between the first and second images in the form of difference data to the movie file, the difference data comprising an array of bytes that represent a Run Length Encoded compressed description.
