AMeador1 Posted July 20, 2021 Share Posted July 20, 2021 I have a Paint.Net (v4.2.16) pdn file with my logo. It is a single layer where the background is all transparent (checkerboard pattern). I have previously saved it as varying png files that have maintained their tranparent backgrounds fine. But now I just edited the pdn and did Save As...png image type - but the background is being changed from transparent to white in the output png file. Am I missing something here? Why is this happening - is there some setting impacting this? Thanks! Quote Link to comment Share on other sites More sharing options...
AMeador1 Posted July 20, 2021 Author Share Posted July 20, 2021 I just figured it out! It was trying to save as 24bit by default - and that seems to be causing it to lose its transparency. Saving as 32bit is maintaining the transparency! 1 Quote Link to comment Share on other sites More sharing options...
Ego Eram Reputo Posted July 21, 2021 Share Posted July 21, 2021 That's right. 24 bits is 8 bits for each of the RGB channels & no Alpha. 32 bits is 8 bits for each RGB+Alpha channel. You're generally best to use Auto-Detect rather than setting the bit depth - for exactly this reason. Auto-Detect chooses the best match for the image. 1 Quote ebook: Mastering Paint.NET | resources: Plugin Index | Stereogram Tut | proud supporter of Codelab plugins: EER's Plugin Pack | Planetoid | StickMan | WhichSymbol+ | Dr Scott's Markup Renderer | CSV Filetype | dwarf horde plugins: Plugin Browser | ShapeMaker Link to comment Share on other sites More sharing options...
