Hi, I'm trying to export an image from OpenSCAD to file. Using the commandline options I've executed this: "%PROGRAMFILES%\OpenSCAD\Openscad.com" -o ballbearing.jpg --imgsize=256,256 --preview ballbearing.scad The only thing that happens is that OpenSCAD displays the usage text. No information about what is missing, or what it doesn't understand. What am I doing wrong? -- View this message in context: http://forum.openscad.org/Export-image-to-file-tp10806.html Sent from the OpenSCAD mailing list archive at Nabble.com.

I guess you have to use filename with .png extension. That way OpenSCAD recognizes you want an image (it does not AFAIK support JPEG images) Miro Hrončok Telefon: +420777974800 2014-12-30 11:30 GMT+01:00 Scalpel78 <frode@lillerud.no>: > Hi, I'm trying to export an image from OpenSCAD to file. > > Using the commandline options I've executed this: > > "%PROGRAMFILES%\OpenSCAD\Openscad.com" -o ballbearing.jpg --imgsize=256,256 > --preview ballbearing.scad > > The only thing that happens is that OpenSCAD displays the usage text.

If OpenSCAD does not support JPG, does it emit an error message somewhere? On 12/30/2014 7:14 AM, Miro Hrončok wrote: > I guess you have to use filename with .png extension.

Don't know, this was just a wild guess.

The problem seems to be the --preview argument. It expects either --preview=false or --preview=true. When just calling --preview it fails without a useful error message. -- View this message in context: http://forum.openscad.org/Export-image-to-file-tp10806p10811.html Sent from the OpenSCAD mailing list archive at Nabble.com.

Yes, the problem is that the preview parameter takes an optional parameter, i.e. --preview or —preview=throwntogether. Since we don’t actually have a way determining the absence of a parameter unless the —preview options comes last, this may fail. Workaround: Always pass the preview option _after_ the main .scad file on the cmd-line. Not sure how easy it would be to fix this. -Marius
