Tested this right now. I used the G’MIC for Windows - Other interfaces latest dev (sorry, but with Windows Visual Studio it’s not so easy to build the project).
My syntax is:
gmic_qt --layers secondLayer.png --output %f mainLayer.png
When I start it, I get an “FileNotFound” error in PhotoLine.
Is my syntax not correct?
As far as I understand the new --layers option, you have to combine your input files to one two-layer image!
Syntax is:
gmic_qt --layers colorful.png landscape.png
Here, colorful.png is the first (top) layer, and landscape.png the bottom layer.
Yes, I found out this from the source code. But it still doesn’t work here. I tested it from command line, too. But it won’t work. On Windows I don’t get an error message, so I don’t know how to find the problem.
Have you recompiled the gmic-qt binary on windows ?
This new feature requires a new binary. I won’t be able to post a 3.2.0_pre binary before next week BTW.
No sorry, I see no way to do it here in Visual Studio. I used the
G’MIC for Windows - Other interfaces latest dev
version.
OK, started G’MIC with one image and see it’s version 3.1.6
To test GMIC_QT with several layers here is an archive for 64bit Windows:

Thank you. I tested this right now and everything works fine.
What’s about output. If I select “Output as Multiple Layers”.
Are there plans to support this?
In my tests, the one and only working file format is PNG. If I send a TIFF, WebP, SVG, G’MIC doesn’t read it. So file formats that support multiple layers are out of the game.
G’MIC-Qt is not compiled with TIFF or WEBP support, in Qt5 those formats are supported using optional plug-ins. Also, the Qt implementation of both formats can only write a single image.
Support for outputting multiple layers was recently added to the standalone version, see gmic-qt/STANDALONE.md at master · c-koi/gmic-qt · GitHub.
I tested this right now.
But it doesn’t work here, like mentioned:
Save the expected output layers in layer_0.png, layer_1.png, …
./gmic_qt -o /tmp/layer_%l.png -p “Layers/Tiles to Layers” gmicky.png
In my command line, there is --output filename_%1.png. But the result is only one file (Array & Tiles > Montage > Output As > Multiple Layers). And the name is filename_%1.png - %1 is not replaced by a number only.
Those changes are not part of the current 3.1.6 release of G’MIC, but they will be included in the next version.
I noticed that there is a prerelease 3.2.0 and tested.
The input of several layers works fine in this version.
But output with --output filename_%f.png doesn’t work.
Why using %f and not %l:
--output filename_%l.png
Sorry, I wrote it the false way.
I tested in the correct way
--output filename_%l.png
but it didn’t work.
Should it work? If so, perhaps I did something else incorrect.
I tested with two images, used “Array & Tiles > Montage” and setup “Output As” to “Multiple Layers”.
I just tested this command:
./gmic_qt --layers --output /tmp/filename%l.png gmicky.png lena.png
With the filter “Array & Tiles > Montage” and “Output As” to “Multiple Layers”
and it works.
I tested again from command line to avoid problems with PhotoLine. But the result is still not correct.
gmic_qt --layers --output test%1.png 01c.jpg 02.jpg
results in one output file
test%1.png instead of test1.png and test2.png
Perhaps the downloadable prerelease doesn’t have this feature?
Well, did you really type test%1 ? %1 is not a valid option, did you mean %l ?
