Salut et bienvenu :) Quoting Olivier Marie <[EMAIL PROTECTED]>: > My questions are : > How can I fill a zone with transparent color ?
First you need to add an alpha channel to your image. Then select the region you would like to erase, and Edit->Clear. > An erased zone (transparent) has an alpha value equal to 0.

To ensure that you have space for an indexed palette entry, you should select a 255 colour palette rather than a 256 color palette during indexing when you want an alpha channel. PNG indexes differently, in that an index entry may have an alpha value from 0 to 255 associated with it, effectively allowing an RGBA palette. Unfortunately, the GIMP doesn't really support that properly (yet?).
