If you need something of similar behaviour, but slightly different, let me know and I'll see if I can code it up. BTW what is a kamashumashua? do you mean the Pelican?

Your the first person who liked my little scheme. I'm going to have to change it a little bit though so as to please more people. I'm going to: - Split up all the functions into separate DLLs - Change the default parent menu items to be the standard menu items But I will be retaining the single XML file that can be used to change the default parent menu items. What will change is that instead of turning off a function in the xml file, you simply remove the DLL for that function.

Thinking about it, this minor issue probably isn't worth mentioning as many users won't know what I'm babbling on about, so I've removed all mention of it. Discussions of limitations are probably best left for the forum

I've changed the web page to read "You might notice that this filter doesn't quite round trip properly when you blend back with the color that was removed, this is likely due to a precision error from working in 8-bits per channel." Paint.NET is a great platform, I hope I can find the time to contribute something a bit more interesting in the future.

Hi Rick, My "Transparency by Color" filter removes the color, to round trip back to the original image an underlying layer needs to be filled with the color that was removed, and then the image needs to be flattened using the built in Paint.NET functionality. After doing this there seems to be some quantization errors which I reported in my bug report post that I linked to, and that you responded to saying it was a GDI+ issue. If you like I can remove the bit about how it doesn't round trip properly. I tried to get around it by biasing the values that came out of the transparency by color filter, but that ended up overshooting the required values.

Unzip the archive, copy the .DLL to the effects directory where Paint.NET is installed. The filters will appear in Paint.NET under the "StewienFilters" parent menu. Optionally you can edit the xml file. Quite likely as what I've done so far is fairly simple. I'm going to add some more filters. Looking through this forum I think most of the plugins are for effects rather than image filters. I just thought I would post what I had already to see if people complain about my setup for example: A) The download is from SourceForge which requires a couple of clicks The filters are grouped under "StewienFilters" parent menu by default C) I've set up a dedicated website with sample images that people have to go to if they want to preview what the filters do D) I haven't posted the source code in a convenient .zip archive

Hi Red Falcon, the links next to the Filter names contain screen shots of what the filters do. I modified the original post to explain this more clearly.

Stewien Filters is a Paint.NET plugin project I’ve just started working on. I’ve got some background in image processing in the medical industry, and I wanted to apply some of that experience to creating Paint.NET plugins. Although what I’ve done so far is pretty simple. I’ve put up some documentation and sample images on a web site with separate web pages for each filter. This is the first release (version 1.2) and instead of releasing all the filters as separate DLLs and hard coding the parent menu into the filters, I’ve instead included an XML file that allows the user to configure which filters are visible, and which parent menu the filters come under. The XML file goes in the same location as the DLL. If missing the DLL will create a new XML file with default options. Let me know what you think about this configuration method. The filters are open source and are hosted on SourceForge as part of my StewienMisc project. The binary DLL, and xml file are in a zip archive that can be downloaded from http://sourceforge.net/project/showfiles.php?group_id=208437 The filters included in this version are (links contain screenshots): Dilate (see http://stewienfilters.com/Dilate.aspx) Kuwahara Filter (see http://stewienfilters.com/KuwaharaFilter.aspx) Kuwahara Filter Modified (see http://stewienfilters.com/KuwaraharaFilterModified.aspx) To Angle (see http://stewienfilters.com/ToAngle.aspx) Transparency By Color Subtraction (see http://stewienfilters.com/TransparencyByColor.aspx)

Visually it might not be much different but it depends what you are using your images for. Paint.NET is a nice proggy for editing data that has been converted to image form. Unfortunately this issue is causing me grief.

When I draw Pixels with Alpha they don't retain their proper value. To Reproduce in Paint.NET 3.36: New Document Select All and Clear Select the Rectangle Tool Select Draw Filled Shape With the Colors Window select ARGB 65,255,255,255 Draw a Rectangle With the Color Picker Tool sample the rectangle just drawn You will get an ARGB of 65,254,254,254 so all the RGB values are 254 instead of 255
