    Erasing a specific color

    Gu-man
      Hello,

      I would like to erase a specific color from a graphic, like a white background, without using the eraser tool. Does anyone know oh to accomplish this in a simple/fast manner?

      Thanks!

              That is a good read. Thanks.

              However, I remember reading somewehere about a yet even simpler method that used the color pallete to delete the color from the graphic (in my case, a white background). Do oyu know about this approach.

                hmmmm .... use the wand tool to select the white area and hit Delete?

                  If you're talking color palettes then perhaps it had to do with
                  exporting the file as a Gif and setting that color as transparent.
                  Otherwise, The Magic wand (as Alex said) should do the job nicely.

                    The magic wand does not work as good as the method described in Pixelyzed (hence the method described there )

                    Jim: how do I set the 'white', let' say, to transparent when exporting as a GIF?

                    Thanks.

                      Gustavo,

                      You would use the Optimization Panel for that. Use Index Transparency.

                          First: thanks very much to everyone for all the contributions. I find these forums "life-saving". What a great learning resource.

                          1) Eraser classic plugin: very nice. I am adding it to my bag of tricks . It seems that you do need to spend some time playing with the controls and going back and forth to check results (like anything else, no?).
                          2) I also tried playing with "interlace transparency" when saving the file as a GIF in FW. Works to some extent.
                          3) I think I have the best luck going around and deleting colors from the GIF palette. It took a bit of time but the results where better (at least with the logo I am working with) than the two previous methods.

                          I have not tried the masking method yet in http://www.pixelyzed.com/pixelforge/removebackgrounds/. After a quick read, sounds like it may still be the approach that produces the cleanest results, though there are a number of steps involved.

                          Thanks again to everyone. Keep up the good work out there.

                          Best,

                            Thanks Alex! My apologies, Gustavo, for not responding sooner. Alex and
                            others have taken good care of you though. :-)
