Writing a .gif animator software
Hey guys, recently i have started to work with website designing and kinda took notice of .gif animation files. I made a search for some freeware softwares and most only allow me to use the software for a limited period. So it kinda struck me why don't i try writing my own .gif animator. So the problem comes,
1) Where can i read up more abt the mechanics of .gif files, i know they r made of .bmp or .jpg files stacking over each other but how do u actually make this work ?
2) Is there a specific API for writing such softwares ?
3) Lastly, just in case im gonna write such a software next time, what are the keywords i should use in google to search for what i wan. For etc, i wanna make a .gif animator so i would needa know the API, and the mechanics to make it.
Ps i've only worked with note-taking programs and their outputs are only .txt files so im still a greenhorn to really making hard-core programs so can someone please guide me.
