How to create an image in Java:

The core librairies of the Java langage have some interesting features, like the possibilite to load image in a single line of code (Gif, Jpeg, etc...). The bad news is that there is anything who tell you how to CREATE such image in Java. So, here is the result of some long search on the Web to find an answer to this question!

One of my best choice, is JIMI. This great library is free for non commercial use, and the GIF encoder is blazing fast. Written 100% in Java, but I had some problem with the Solaris JDK....

The ACME package contain some fine package, and especally a gif encoder. Unfortunatly, this encode only works with 256 color (or less) images: if the image have more than 256 colors, you have to do yourself an operation to reduce colornumber (GIF files can only have 256 col max). But full sourcecode is fully available.
Mark Watson have done small modification on this package, to be used with his PicWeb utilities, to remove the 256 col limitiations. PicWeb is available with source. Unfortunatly, the way it was done only work with very small images...

The gillog Java Page contain some code who claims to save gif files, but I was anuable to make it work, and sourcecode is not available.

Now, another problem:: with JDK previous to 1.2, you can't create Image without aving an AWT window to display it.
