Hi,

I have a GIMP image with transparency set. I've read that TIFF supports transparency, yet when I try and save my image as a TIFF I have to 'flatten' it first, which removes the transparency.

Is there a way in the GIMP to create a TIFF file with transparent areas?

Thanks,

Greg

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.

Try a merge visible (under layers) _before_ saving. This will maintain transparency.

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.

Thanks,

Greg

The GIMP TIFF plug-in supports saving single-layer images with alpha channel. You shouldn't get an export dialog. What version of GIMP are you using?
