Hello community,
I have 2 beginner’s question regarding Natron.
I have a PNG with transparent areas in it. I would like to use it as a graphical object, applying effects (for example dropshadow) to it. Is that possible in Natron, to use PNG with Alpha Channel as a graphical object?
I can’t seem to have that PNG + Alpha Channel to be on top of a solid background, part of the PNG Image gets cut off. Is the problem the encoding? PNG comes out of Blender.
Thank you for your time.
Pics?
I got it to work. Reason why it didn’t work before, was a messed up xcf-file.
By the way, Natron doesn’t read newest GIMP XCF File (GIMP 2.10.10) with its read-node.
Can you confirm that?
Natron (the ReadPSD node) uses ImageMagick to read XCF/PSD images/layers. The ImageMagick version distributed with Natron 2.3.14 does not support XCF files from 2.10. I will however make sure the next version of Natron has updated support for Gimp.
I will need to downgrade ImageMagick to 6.9.10-52 since ImageMagick 7.0.8-* breaks other plugins in openfx-arena.
Since ImageMagick v6 is legacy it will not get new features. I will go through the v7 code and make a backport of the Gimp 2.10 support for v6.
I think you’d better go fixing the plugins, because that doesn’t seem like a very durable solution:
Will you packport to IM6 every single interesting feature from IM7?
Which plugins are broken?
I have backported the gimp changes to v6 already and can provide a patch. It’s only the xcf coder.
I will try to find the issue with v7 later this weekend. All the plugins worked fine in v7 earlier, so something has changed (in IM).
On another note I have finally got a working Windows SDK up-and-running. I had to use an older snapshot of MSYS2 to get a working toolchain.
It breaks in 7.0.8-13, they did some modification to morphology. I’m testing if the plugin(s) or IM needs fixing.
EDIT: It’s a bug in IM.
