Re: [Gimp-user] flat image bg color change
Thanks Carol, Mark and Malcolm. I've been experimenting with all the suggested methods and getting various results. As far as making it trasnparent (how, when, why), I could use some advice. :) On Tuesday 02 November 2004 02:31, you wrote: hello, On Tue, Nov 02, 2004 at 01:54:19AM -0500, Tom wrote: Thanks Eric.

Any ideas would be appreciated. sounds like you are handling the image fine, you just need to take a few more steps with it. because the background is almost all of the same color, selecting by color or contiguous color areas is the quickest. (that is what you did). additionally, under the Selection menu is Feather. this option takes away the jaggies. you figured out how to make it transparent? carol ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

This extra color can be added while working with gimp on this image with no problem. There are a few different ways to add this extra transparent color. From the menu, Image --Layer --Transparency --Add Alpha Channel. or from the Layer Dialog, right click next to the thumbnail and select Add Alpha Channel. To remove the alpha channel so you can save as a jpeg again, Image --Image --Flatten Image. This will cause any transparent areas to be filled in by the background color you can see on the gimp toolbox. carol ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
[Gimp-user] flat image bg color change
(new to gimp) Hi, I would like to change the background color of a photo, (preferably with a gradient or shadow effect) but it's a single layer (jpg). I tried to 'select by color' and replace it, but the edges of the object in the foreground turn out jagged and looks bad. I also tried to invert the selection and cut and paste it into a new image file, but it looks just as bad. Any ideas would be appreciated.

There are a billion different ways to do what you're talking about. But it really comes down to the quality/properties of the image you have. Show us what you have.

There are two tutorials about this at http://www.gimp.org/tutorials/ (in the intermediate section). As has been mentioned in another thread, the best technique varies a little depending on the type of image you are working with, but those two tutorials might give some starting points.

Re: [Gimp-user] flat image bg color change
I would use the path tool to trace the outline of the bottle, then change the path to a selection. Then you can float the selection and put the layer on a different background. The path tool takes a bit of practice but I think it will produce the best results in this situation. Tom wrote: Thanks Eric. Here it is.
