Gimp XCF file format

[blackearth2014]

Can Natron read Gimp's multi-layer image format. I use for all of my graphics and matte painting work on the Mac. It would save a lot of time to be able to have this feature.

Requires writing an Xcf reader in openfx-io
Please file an issue in openfx-io, and if you have a source for a usable xcf reader (non-gpl), please point to it

ImageMagick/GraphicsMagick is able read xcf, http://sourceforge.net/p/graphicsmagick/code/ci/default/tree/coders/xcf.c

I guess making an image magic reader would be helpful then

It would be very helpful if you can read separate layer so that a XCF
project file can become an already layered project in natron
Pretty like other software does with PSD files

The thing is the concept of layer doesn't translate automatically into Natron. The only thing we could do is add a choice box in the settings of the reader where you could choose the layer it reads

[fPaglia]

I see.
Maybe the concept of layer can be easily translated in a series of read
each of which point to a layer of the original XCF.

That would be nice, but the graph layout in its current development would be overwhelming. We would need a group node like in nuke to house the multitude of layers. Also, the compositing modes will have to be coded into Natron as well. Natron doesn’t have some of the layer modes.

You mean a group node with several outputs? that would be great

[blackearth2014]

I am talking about an other type category node like the Dropbox node but this node encloses or combine all the nodes into one node that shows up in the graph. When you double click the node it opens up a sub graph with the other layers files with the merge nodes.

Please visit this link to see what I am talking about - http://youtu.be/19w3vkFp5X0.

The group node with multiple outputs does sounds interesting.

I can tell you that with what we're developing for the Tracker interface, implementing group of nodes is a few lines of code away

[olear]

Getting old, will start to look into a XCF/PSD reader with layers. Can't give any time frame since I'm very busy this summer, but have usually weekends free.

[blackearth2014]

Great

[olear]

I'm able to extract layers, is the complete image required(all layers on top of each other, what you see in gimp)? If so will take some more effort, also unsure if all features from Gimp can be implemented. I do know that Inkscape/Krita uses GraphicsMagick, so I should at least be able to replicate what they do.

Still a long way from a complete plugin, just testing.

[olear]

Sorry for the late reply, but got some time today to make a proper read node, stuff seems to work, and I can soon provide a ReadXCF and ReadPSD plugin.

[blackearth2014]

Thanks

[olear]

I did however notice that exporting to PSD from GIMP produces better image in Natron than loading the XCF... Could be some merge option used in the XCF or something.

Current state:

[MrKepzie]

I'm closing this since it's taken care of in openfx-arena

[olear]

Still not complete, but soon.
