Make Palette Plugin v1.0 (February 15, 2021)

[geist_ 1]

VERSION: Only checked for paint.net version 4.2.15.

 

Adjustments > Make Palette(.dll)

 

As the name suggests, from the current selection the plugin/adjustment will make an "UntitledPalette.txt" file in your \Documents\paint.net User Files\Palettes with each color taken only once.
It also displays how many unique colors are in the palette.

@geist_ thanks for sharing your plugin 🙂. I tried it on two different images and it created a separate palette for both but it only created the palette with the color most used in the image. I do have 2 requests if they are not too much trouble. Could the plugin save the palette to Documents\paint.net App Files\Palettes instead? That is where the other palettes appear. And lastly, is there a way to allow the user to give the palette a name before it saves? I have included the 2 images I tried the plugin on and provided a link to the corresponding palette that was created. Thanks again for your time to make the plugin.

 

Image 1 and link to corresponding palette:

UntitledPalette1.txt

 

 

Image 2 and link to corresponding palette:

UntitledPalette2.txt

Moved to the 'Plugin Developer's Central' area.

 

@geist_, your code has some serious issues.  If you post the source, we can help you fix it.

@toe_head2001 @ANONYMISS I think the reason it crashed is because it's supposed to store the file in C:\Users\name\Documents\paint.net User Files\Palettes\ 

which i thought was made by default. Also @Ladybug thanks for checking it out, it means a lot! The main reason i made this was for characters/item sprites, not really for landscapes, and yes, i will change it so the user can choose a name for the file before it saves it. Here's the source code:

@geist_ I tried it again on one of my images and it did create more than one color but the colors looked washed out. Then I tried it on a sprite image and it worked beautifully. The image location still needs a bit of editing since it only saves it to Documents\paint.net App Files\. Just add the Palettes folder name. It did not give me the option to give it a name but perhaps you are still working on that. Thanks for sharing your coding abilities with some of us who have none, lol. Others on here are very well versed and can help you tweak the plugin if it needs to be.

Just a tad discomforted that this plugin is working  ,i.e doesn't crash for  @Ladybug.

 

Why so?

[Ladybug 264]

@ANONYMISS, not sure why. It is odd. I have the classic release of PDN. I put the plugins I download in Documents/Paint.net App Files/Effects and after the palette is rendered I move it to Documents/Paint.net App Files/Palettes. I hope that may be of help in comparing your setup and why it may be crashing.

Thank you @Ladybug.

 

I use the classic release (in Windows 8.1  - cue booing from offstage) and placed the.dll in the Effects folder.

 

If it gets to be up-and-running I'd find it helpful.

 

P.s. But the present duplicitous behaviour is odd.

@ANONYMISS, the only difference then is the version of Windows. I have Windows 10 (I will boo for that one but had to upgrade since it was a new computer).

@geist_, looks like you were trying to reinvent the wheel a bit.

 

Here's a simplified version. Let me know if you have any questions about it.
