Custom Palette does not work for palletized export of PNG

Recommended Posts



when exporting PNG, the option "Palette" -> "Custom" doesn't seem to work. There is no way to define which custom palette to use and when attempting to export that way all I get is an error dialog saying "An error occurred while exporting to: /Users/peter/Desktop/test.png"


If I'm using this wrong I'd like to know how it's supposed to work, but since I don't see any additional UI to make it work I'm filing it as a bug.

If it's not meant to be there maybe it would best be removed from the drop-down.


It would be helpful for app development for embedded wearables which have displays that support only a very particular palette of 64 colors. (Smartwatches, Fitness Trackers)

e.g. https://developer.pebble.com/guides/tools-and-resources/color-picker/

Hi Peter,

Thanks for letting us know. I've been able to reproduce your issue so I'll get it passed onto development. I can't be sure but I think it creates a PNG using a palette of just the colours in the document. However as it stands it is failing to export

I'm also experiencing the same export error for both PNG and GIF exports. Given how much time has passed since @lastfuture brought this up, I'm surprised that it's still an issue. Is it possible to get any feedback on this?

Oh, still in development? You've had plenty of time to remove that option from the UI. What is it actually good for? I need to reduce an image to four colours, the four CGA colours to be precise (black, white, magenta, cyan). Can't find a filter to do that so I tried my luck in the export.

Well, paint.net could do the job now. Almost. It could export with 4-bit colour, I needed to rework to get 2-bit.
