Convert TIFF to PSD and keep transparency

[jansuhr]

Must be a bug or something in the Mac version. If I run it in a PC with the following command:

Code: Select all

convert "Transparent.tif[1]" Transparent.psd

It works and create a proper transparent PSD

Works fine for me on my Mac OSX snow leopard with IM 6.9.3.2 Q16 and LIBTIFF, Version 4.0.6. Perhaps you need to update your libtiff on your Mac. I can see transparency in my very old PS (CS) in the psd file create by your command above.

With HomeBrew the latest version is the one I have. I'm not that comfortable with doing a Terminal installation of any higher version. I have LIBTIFF 4.0.4 Where can I find an update of that one?

Thanks

LIBTIFF 4.0.4 should be sufficient. But since you install via Homebrew, you would have to use Homebrew to upgrade it.

Sorry, I do not know what else to suggest other than scrapping Homebrew and installing from say MacPorts, which is what I do, though I only install delegates from Macports and install IM manually. See viewtopic.php?f=1&t=21502&p=88202&hilit ... rts#p88202

Ok I Installed over MacPort and got 6.9.2-10 and the command now works getting me a transparent PSD.

Must be some bug in the version I got.

Thanks for excellent support!!

There is something strange about both TIFF files you have posted. Gimp and Microsoft Photo Viewer can both see only the first image. Both programs can normally see all images in a TIFF.

I don't know enough about TIFF internals to say what is causing the problem.

[jansuhr]

Well it is just saved as TIFF in Photoshop CC2015 with layers and transparency.

Yes, that figures. I suppose it has been saved as one image with two layers, rather than two images.

[jansuhr]

Photoshops saves layered files with a "Compatibility layer" on top of the layers in the file. The Compatibility layer is what is shown on screen.

To be able to have transparency in a TIFF you have to have one layer instead of the background layer.
