While I did use a slightly different HSV to RGB routine, I did use HSV colors for my Pastel plugin. Source code is around here somewhere... EDIT: http://forums.getpaint.net/index.php?/topic/2045-pastelwater-color-plugin-updated-2008-02-18/ Now, let's see if I can find the source code...

One of my tutorials has a section on it. http://boltbait.com/pdn/CodeLab/help/tutorial4.php Hope this helps.

Try this one: http://forums.getpaint.net/index.php?showtopic=1957 It handles HSV gradients.

One day I'll write a tutorial on how to use my effect and you'll understand why it is perfectly located.

In paint.net 4.0, if you hover over an effect name in the effect menu it gives you info about the effect including auther and DLL file that contains the effect.

RAW support is not built-in, but there are several RAW filetype plugins. Just pick the one that works for your flavor of RAW file.

Make sure your namespace is unique.* *I have not looked at your code yet.

What OS are you installing on? Are you using the admin account of that OS?

Where do you think the translations like this come from:

...and there was dancing in the streets!

You are right. The Amount variables are read only. This is a limitation of the Paint.NET plugin Indirect UI.

Here is some code to do that: http://forums.getpaint.net/index.php?/topic/18105-line-drawing/

Maybe Paint.NET is installed in a different place. Try this: Find the Paint.NET icon that you double-click in order to run Paint.NET. Right-Click on it and choose "Properties" from the menu that shows up. Click the "Open file location" button. In the windows explorer window that opens, double-click "Effects" folder. That's where the effect dll files are supposed to be installed.

That's not something a plugin can do. HOWEVER... Have you tried scrolling with your mouse scroll wheel? It works for me.

There's your problem right there. ONLY download effects from this web site.

I'm not exactly sure what you're asking for here. But, if you're asking if you can print out the tutorials on this site, bundle them together in a printed book, and redistribute it for profit... then, no you may not.

Is there more of an error message? If so, list the entire thing here. If not, give us a screenshot of the error that does come up.

Have you tried this plugin: http://forums.getpaint.net/index.php?/topic/24587-normal-map-renderer/ Or this: http://forums.getpaint.net/index.php?/topic/23936-the-normal-tools-v-011/ Or this: http://forums.getpaint.net/index.php?/topic/21224-heightmap-v13/ with http://forums.getpaint.net/index.php?/topic/2534-normal-map/

In the following window, select "Open Paletts Folder": In the Explorer window, go up one level from that.

Paste onto its own layer. That's how Paint.NET works.

There is a setting in the Save As dialog box that controls the PNG transparency mode. Make sure that it is set to "Auto" instead of 24 Bit.
