@ReMake Your detective skills are outstanding! I was able to download a copy of Centerlines.dll and Centerlines 2.dll from the links that you provided from the Way Back Machine.

Add this plugin to Paint.NET as directed, Then open the PDF in Paint.NET and save to any supported file type.

I just tried the same thing and saved a file as a .PDN and had no trouble opening it. If you saved a multi layered file as .PNG it will merge all of the layers asks you to confirm before completion. Once merged that can't be un-merged. I have altered a file extension by mistake but renaming it back to the correct extension did not prevent it from opening. It appears that some other event has occurred that you have not mentioned or are unaware of.

I opened your above image in Paint.Net and I see that it is a gray scale image with an alpha channel so that it is transparent. I also see that it contains ~254 shades of gray. Is this what you are trying to create? Do you need 254 shades of gray? The other PNGs above this one, have lower color counts. Two of your .PNG images have a 32bit color depth while the Mad City image has an 8bit color depth and only 95 shades of gray.

@paveld I look at the Exchangeable image file ( Exif) data of my .PNG files created in Paint.NET and could not find any data on how it saves the gamma (gAMA). It is possible to save the gamma setting in a .PNG image, but some images viewers ignore this setting. Images can look more or less contrasty (my word 🙂 ) depending on its gamma setting. This may be the cause of various viewer/editors displaying you image differently. I prefer a gamma ~1.6. Others prefer settings between 1.5 - 2.0.

I think that what you are looking for is the Shape Tool. It has 29 shapes when installed and more .xaml shapes can been added to the Paint.net/Shapes folder: https://www.getpaint.net/doc/latest/ShapeTools.html Additional shapes: https://forums.getpaint.net/forum/48-shapes/

If I am not in error; GIF files are 8 bit and can only contain a maximum of 256 colors. Also it can contain only 64 intensities of a single color. Your gradient, as a true color PNG, may contain several hundred intensities of that color has to be consolidated into groupings that cannot be greater than 64. That is why you will get the opaque groupings.

To get rid of the blue gradient from the transparency cloud image, select the Wand tool and set the Flood Mode to Global and the Tolerance to ~25. Next click on the blue gradient on the cloud and delete it. Do the same for the remaining shadow gradient on the cloud. This should give you a a pretty nice contour image rendering. (You may have to tweak the Tolerance levels)

There is also a Gaussian blur + by BoltBait the has over a dozen blend modes

I did find that one and I think that it will do the job, but the one from 2010 that I was thinking about is not at the forum but I did discover a link to it here: Link sets off my anti-virus software's PUP alert. I will do this search since an effective solution has be offered

The use to be access to a plug that does what Welshblue has illustrated. It was called the Manual Color effect which is the PdnManualColorFilter.dll by MP4 Builder Team (c)2010 When installed it would reside in the Effects > Color group Link to it are no longer active here. I guess that I have a bunch of legacy plugins that are not listed anymore! 🙂

In the old days I wanted to be the first to try every new tweak. I even had a few clones of OSs around so that I could just unlock a my hard drive bay and insert a functional backup and reboot when things got hairy, but now, "Ain't nobody got time for that!" 🙂 Keep up the good work!

What's a few milliseconds among friends? 🙂

I never let alphas and betas install automatically. I'm just fussy like that! 🙂

This is a Windows feature. Right click on the image icon, when the menu opens, go down to Properties and select it, then check the Read Only Attribute.

@lifeday I am sorry to hear that you are having difficulties! I have made the G'MIC updates and have preformed several test with the Stylize effects and could not get a crash. I did not load the current Paint.NET alpha, did you?

Great point!

I have not experienced any problems with the current 1.3.0.2 version of The Dwarf Horde Plugin Browser.

I am not aware of any place in the app where after changing the canvas size, you can make that change a default setting. My work-around is to create a blank canvas of the desired dimensions and save it as a .PDN file and then launch it with a double click to open Paint.NET when it starts. Then you can have a series of custom sized PDN templates to launch as needed. You can assign them meaningful names such as 1920x1080.pdn or 5000x5000.pdn.

@Collector I have installed the Plugin in and it will upon the Photoshop .pat file onto the a canvas, it is not implemented as a fill option. It is not ready for prime time as a useful fill pattern. To use the .pat file you will unzip the archive an open in Paint.NET as you would any other of its readable formats. It will open on a canvas and there it sits. The plugin has no documentation as to whether it can really be use as a fill element. I seems that the pattern can just be opened.

I am not sure, but there is a 'FileType' Plugin that enables you to use PhotoShop patterns and in PhotoShop the patterns can be used as Fills. I have not installed the Plugin but I will do it later to see if it works for Fills in Paint.NET.

Here is one way to accomplish your goal. I have selected an image with the dimensions of 1920 x 1280 pixels. I want to divide in half (50%) vertically. half of 1920 = 960 I choose the Rectangular Select Tool and the Fixed Size option Next:
