Hello everyone,

Is it possible to define a colormap using the CSS module?

Thanks

Chris

No, you can’t do this right now. I’ve actually been working on it a bit recently (raster styling doesn’t work all that naturally in CSS, but it seems like a prerequisite for styling transformations):
https://github.com/dwins/geoscript.scala/commits/raster-styling

If you’re interested in trying it out I’d love some feedback, but I don’t think I can support builds of this experimental branch, so you’d have to build it yourself from sources (feel free to bug me off-list for details.) I don’t have things documented yet but at least the property names for raster styles are all together in the sources: https://github.com/dwins/geoscript.scala/blob/9ff23dccfed0201f3c05cde80456386336323f70/geocss/src/main/scala/org/geoscript/geocss/Translator.scala#L622-L644

A basic raster style would look like:

  • {
    raster-channels: auto;
    raster-color-map:
    color-map-entry(black, 0)
    color-map-entry(red, 100)
    color-map-entry(green, 200);
    }
···

Thanks David.

I will try to take a look when I have a few spare moments as I would love to be able to keep all my styling in CSS without mix and matching with SLD, so once I get around to looking at it I’ll happily provide feedback.

Thanks

Chris
