fstieglitz Posted June 10, 2010 Share Posted June 10, 2010 Hello. I searched this forum (and probably missed it) but I could not find the correct method, so i will go ahead and ask. A 3rd party provided me a PNG file of a hand-drawn image with a white background. What is the best way to convert this image so that all the white areas are really transparent? Many thanks.

ptuZ Posted June 10, 2010 Share Posted June 10, 2010 use the Magic Wand to select the white areas and then delete My Forum Gallery My dA Gallery Graffiti tutorial Link to comment Share on other sites More sharing options...
pyrochild Posted June 10, 2010 Share Posted June 10, 2010 use the Magic Wand to select the white areas and then delete This will likely result in jaggies and stray almost-but-not-quite-white pixels around the edges of the lines. Search the Tutorials forum for things relating to Alpha Mask(ing) for a cleaner solution. ambigram signature by Kemaru [i write plugins and stuff] If you like a post, upvote it!

Reinhard Posted June 13, 2010 Share Posted June 13, 2010 I use the Bucket (fill) with a full transparent color. You have to change the tool parameters from "Normal blend" to "Overwrite" in advance, or you won't see any effect. You can access the parameters after choosing the bucket. Press the little chemical bottle icon, in the right to the fill tolerance slider. Link to comment Share on other sites More sharing options...

Ego Eram Reputo Posted December 12, 2010 Share Posted December 12, 2010 On the Color Window, click the More button. The Transparency - Alpha slider is the one that affects the transparency of the currently selected color. 255 = fully opaque, 0 = fully transparent. Note that transparency is indicated by the grey & white checkerboard pattern. 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...
