R: Managing GIF with trasparency without loss quality

[Pirola Davide-2]

Hi all,
I am novice in a image processing, and i never used ImageJ... so i need help. :-)

i'm using java AWT in order to generate a GIF image that contains a text and an icon. (icon is a png 8bit readed from filesystem)

All works fine, but this GIF image must have a region transparent.

The only way i found to obtain this result is this code:

It works!... but the quality is bad. In the resulting image there is some noise, and the colors are different from original (es: background is #FCFCFC instead of #FFFFFF). This is because the color table used for trasparency are not optimized (i think).



Question:

There is something in  ImageJ that can help me?

For example some class that i can use to optimize the color table or for directly generate the image i need (substituting the awt).



Thanks

Davide
