Export an XML file describing layer positions

[MarcRX]

When working on HMI grafix it would be helpful to export an XML file that describes where on the canvas the layer is located. That way it can be read in to other tools (like programming IDEs) automatically.

This is quite a specific feature, and I'm not sure if it falls inside the scope of the plug-in, but I'll see what I can do.

Should the XML tags have specific names?

I'm thinking that the exported metadata should be comprehensive and contain all information there is about a layer, not just its coordinates (name, opacity, mode, ...), which could also prove useful.

It would be enough to mention the name of the generated grafix and it's layer 0,0 position on the image canvas so that the programmer can use this to put the grafix element on the screen of the target device. Occupacy is already part of the generated grafix. What would be helpful is a flag that represents visibility of the layer. That way the startup content could be defined but at the same time also the position of the layer/grafix that are unvisible are still part of the description XML.

I created a separate plug-in for exporting metadata to several formats, including XML:

The resulting XML contains image dimensions, layer dimensions, layer position within the image and tons of other metadata (visibility, opacity, etc.).
