I created a TIF in Photoshop with a transparent background (Dropbox - test.tif ).
Now my problem is that any other 3rd party tool (e.g ImageMagick, Gimp, ...) can't see this transparent and in consequence I can not remove this transparent background either.
Is the transparency in Photoshop generated TIF files so special?
Thanks in advance

Most likely the problem in other applications is they don't support layers in tiff files, thus your seeing flattened version of the tiff.
Most non adobe applications don't support layers in the tiff file format and just so you know adobe owns the tiff file format.
If you were to save the same file as a psd, then Gimp, for example, would show the transparency.
Also. while gimp recognizes photoshop's layer groups it doesn't recognize shape layers so they would have to rasterized in photoshop and then saved as a psd.
However, you should simplify your layer structure as much as possible, so other applications can open the file as you see in photoshop. For example, with your image, just one layer containing both rasterized shapes and no groups/artboards would be best. Also, pngs would probably give max compatibility with other applications.
In Gimp you can get back the transparency in the Test.tif by using Colors>Color to Alpha to remove the white background.
In Gimp 2.10 one needs to add an Alpha Channel first before using Color to Alpha.
Right click on the Layer thumbnail and click Add Alpha Channel.
Just to add that if in photoshop one adds an Alpha channel from the selection of the transparency and saves the image as a TIFF that many applications will then open the TIFF with transparency.
gimp 2.8 and older
Your test.tif saved as a psd with the shape layers rasterized and open in Gimp.
Jeff, one caveat: didn't Adobe sumit the TIFF format to the ISO for standardization?
Yes, i believe your right.
I think I found the solution.
The solution which works for me is to remove the profile "tiff:37724".
Is there somewhere a list of special adobe profiles like this one?
That specific tag is covered here in the TIFFphotoshop.pdf
Seems that tag has to do with layer data, so removing it might flatten the tiff file.
thank you for the quick answer. Do you know a way to do that with ImageMagick?
My Problem is, that I get an Image like the example above and can only use ImageMagick (because of automation).
I only want to replace the transparent background with a white background and save it back as tif.
In a short way:
Sorry, i'm not that familiar with ImageMagick, but wouldn't it make more sense anyway to use photoshop, since the image originated from photoshop and you would not have to worry whether your software will read the file properly or not.
Photoshop can batch process folders of images if you need automation.
Pls I also have a jpeg file which I opened on photoshop, only to find the gray and white box lines around the main image. I'm finding it hard to remove the box lines (transparency) from the image and make it plain white instead. When I use the move tool to drag the image on photoshop, the box lines follow it around. Pls how do I get rid this from photoshop?
Thanks in advance
Can you post some screenshots of what your seeing?
What operating system are you using?
Hi Jeff, I have found this useful video that helped me with my image.
In this video, it explains how to use a quick selection to select the checkered box lines, making a selection around the image and delete it. It worked perfect for me, if anyone is still stuck with this same issue, he can use this method. Watch till the end. Best Regards
