Re: [Gimp-user] Preserve transparency in a TIFF
Hi Eric, I don't have multiple layers, my transparency is in an 'alpha' channel, so there is no 'merge layers' available. I can add a new layer, but I'm not sure how to get it to show transparent areas.

[Gimp-user] changing the size of selections in GIMP
Dear list members: I've already asked this but haven't got any response. How can I change a selection's (eg rectangle) size without reselecting again? Thanks, IG ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

Thanks, IG You can increase or shrink the selection by a given amount of pixels with Select-Grow and Select-Shrink respectively. Gimp 2.4 will contain a new select tool thanks to William Skaggs, but until then, there is no interactive way to resize a selection once you have done one. But there are many interesting option in the tool options to constraint the selection size or aspect ratio.

The scale tool (as well as move, rotate, shear, change perspective and flip tools) can be applied to a selection as well as to a layer.

Re: [Gimp-user] Preserve transparency in a TIFF
Hi Sven, I'm using version 2.2.4. I've figured out what the problem was -- the image wasn't in RGB mode, it was 'indexed', which I guess doesn't support the alpha channel in TIFF.

[Gimp-user] Alpha Channel
I wonder why, when Opening or creating a document, there are only 3 color channel and then, when creatin a layer, the alpha is coming. What this stand for ? Cedric ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

What this stand for ? The default setting for a new document is the RGB colorspace with the document filled with the background color; no transparency is needed. When you add a layer, if you change nothing, the layer will be transparent, so an alpha channel is required at that point and one will be added. You can set up a new document to have the background filled with transparency (under the advanced options tab in the new image dialog box) and then you will have an alpha channel from the start. However, if you create a new layer filled with the background or foreground color, that will still add an alpha channel if you do not have one in the image, because there are always transparency options available for layers.

[Gimp-user] Image substraction available?
