I'm trying to use the command line interface to generate some part preview images in PNG format for a project's web documentation. However, the default background color used appears to be some sort of hideous off-yellow, and I can't find anything in the documentation that explains how to change this. Is this possible? If transparent backgrounds aren't supported, how can I at least change it to pure-white? -- View this message in context: http://forum.openscad.org/Setting-transparent-background-tp18272.html Sent from the OpenSCAD mailing list archive at Nabble.com.

In the GUI, in the Preferences, under 3D View, you can set a color scheme, which also sets the background colour. The Nature color scheme uses a white background. There is a CLI option for setting the color scheme, but it doesn't work for me (on MacOS anyway), only the GUI works.

It’s also possible to add your own color schemes: https://github.com/openscad/openscad/wiki/Path-locations Better docs are needed. There is a pull request for adding support for transparent backgrounds, but that also requires a bit of work to get to work properly across platforms: https://github.com/openscad/openscad/pull/1485 Doug: This should also work on Mac, and does for me: ./OpenSCAD.app/Contents/MacOS/OpenSCAD sphere.scad -o out.png --colorscheme=Sunset -Marius

A bit clumsy, but I just use Paint Shop Pro: File->Export->PNG Optimizer Transparency Tab - Single Color Transparency - Areas that match this color: 255:255:229 Tolerance: 0 -Trygon -- View this message in context: http://forum.openscad.org/Setting-transparent-background-tp18272p18279.html Sent from the OpenSCAD mailing list archive at Nabble.com.

Thanks, I didn't realize I could create new schemes by dropping a JSON file into my home directory. That works.
