Creating an animated gif fileLogo allows the user to save each frame of an animation in an animated gif file
Step 1: We set the active area Step 2: The first frame is drawn Step 2: We do not append the first frame to the file. The file will be overwritten Step 3: The other frames are drawn and appended to the gif file Step 4: Step 2 & 3 are repeated until completion
The example below creates an animated gif:
