Could explain more about what you can't do wth tiffs?
Have you checked under Image>Mode to see if the tiifs are RGB Color and 8 bits/channel?
You can post a screenshot if you feel that would help.
Yes, it is RGB/8 bit. On some tiffs it works and on others it does not.
It works on all jpegs. I had to add a blank canvas, and then paint it
around the edges to get a black border. Not much fun, but it worked. I
used the select tool, and paint bucket.
Perhaps some of the tiffs are already layers.
In other words, since jpegs don't support layers, they all ways open with one locked background layer, but the tiff format does
support layers so the tiffs don't have to have a locked background layer and can already be a regular layer that supports transparency.
For the tiffs you could add a new color fill layer below and use the color you want the enlarged canvas to be.
On pse 10 look at the bottom of the layers panel for the new adjustment of fill layer icon
Thanks a bunch. I think you have given me a solution to my problem. I
have not tried it yet, but I was using a layer after deleting the
background. Probably going to get me into trouble. Now I just need to
figure out how to make my final image a background layer again.
When you open the tiffs you can flatten the image and the canvas size dialog will have Canvas Extension Color enabled
or you can flatten the image after using layers before saving if you don't want a layered tiff file.
Right click on the layer thumbnail in the layers panel and choose Flatten Image.
As you suspected, I was not using a background image. I had deleted my background layer. When I converted my tiff image back to a background layer, the canvas color worked.
Thanks so much
