How to chenge the background color when exporting PNGs. by

I'm using the command line export to PNG option.
and I'd like the background color to be white on the exported images insted of the yelowwish that comes by default.

How could I do this?

Best!

You can use a program (e.g. XnConvert) to change the color:



Otherwise you would have to change the source to allow specifying the background color.
WYSIWYG. Export simply turns the visual display into a PNG file.

To do this from a BATCH file use: nconvert -replace 255 255 229 255 255 255

In version 2015.03 go to edit --> preferences --> 3D View
This will list different color options, some with a white background.

None of the options have a WHITE background.
"Tomorrow" has a LIGHT GREY background.

So I copied "Tomorrow" to "Tomorrow-Day" and changed the background to WHITE (attached).

It is easy to do, just go to your color-schemes\render directory (for me this was "c:\Program Files\OpenSCAD\color-schemes\render") and then copy the theme closest to what you want to a new name then EDIT the file and change the "name" to the "NEW NAME" and the "background" to "#ffffff". Save the file, restart OpenSCAD and select your new color scheme.

Thank you very much for your help guys. But I belive I didn't made myself clear.
I'm not using the graphical user interface but the COMMAND LINE

oepnscad.exe "C:\Users\ale\iphone6Dec"scad -o "C:\Users\iphone6Dec_tdg2hliiF1_View.png" --camea=0,0,0,0,0,0,200 --imgsize=188,368

Now after exceuting this i get this result. I want the yellowish to be white on the COMMAND LINE export

as far as i know there isn't actually a way of specifying the background color via the command-line which is a bit of pain , i'm currently looking at using image magik or the previously mentioned xnconvert to fix the problem ,

AFTER defining your new render color scheme ("Tomorrow-Day" in my case) then add "--colorscheme=Tomorrow-Day" to your parameters for the OpenSCAD.exe!
