cloucibe Posted November 10, 2012 Share Posted November 10, 2012 I want to remove only semi transparent pixels in a image. I want to keep others without changing them. How can i do that? And is it possible to increase/decrease of all semi transparent pixels at one time? For example: When i choose the increasing tranparency-alpha value at 20 if a pixels transparency is 120, it will be 140 if 75, it will be 95 if 255, keep it same if 0, keep it same sorry for bad english.

pdnnoob Posted November 10, 2012 Share Posted November 10, 2012 BoltBait's transparency plugin will work well if you are increasing opacity Quote No, Paint.NET is not spyware...but, installing it is an IQ test. ~BoltBait Blend modes are like the filling in your sandwich.

cloucibe Posted November 10, 2012 Author Share Posted November 10, 2012 If there were a option like "ignore opaque pixels" that would be perfect for me. Looks very useful plugin btw. Quote Link to comment Share on other sites More sharing options...
pdnnoob Posted November 10, 2012 Share Posted November 10, 2012 As a workaround: 1. duplicate your layer (ctrl+shift+d) and use the brightness/contrast adjustment to set the contrast to 0, then use hue/saturation to set saturation to 0 as well. This should get you a layer where the only difference between pixels is the transparency. This allows you to: 2. use the magic wand (set tolerance to 0%) to select all the totally opaque pixels. 3. Once you have them selected, invert the selection (ctrl+i) and turn off the visibility of the grey layer. This gives you a selection of all the pixels that are not totally opaque, effectively ignoring them. Now you can adjust your transparency without disturbing the opaque pixels!
