Images often have dirty pixels, that are almost a certain color, usually white. PixelWasher can remove these pixels. The result is the output image is smaller in size, and is easier to edit.
Pixels are replaced based on threshold rules defined by the user. A rule can be simple using "and", "or", and "(" ")" brackets, or a rule can be written in C#. Examples are provided in the "Rule" combo box. Advanced users can use the C# code option to return Color objects with different Alpha values based on the original pixel color and location.
The "Replacement Color" can use an Alpha value of 0 to make those pixels completely transparent.
Requires .NET Framework 4.5.2 or newer. This software might require the full .NET framework as the System.CodeDom.Compiler library is used to compile the Pixel Wash Condition rules.
Please rate and/or review the software.
