Effect Request: Polar to rectangle

[barkbark00]

I know we have the Rectangular to Polar Conversion plug-in Thanks to Programmerman. but what I need is the opposite... a polar to rectangular effect. Maybe BoltBait could tackle this one. Anyway, It would be really awesome! Thanks in advance.

[TinSoldier]

Yeah, I wondered about that one...

[BoltBait]

Heh. Don't ask me to write an effect... I'm terrible at it. And, the worst part about it, if I did write one, I wouldn't know how to put a UI on it.

[Rick Brewster]

Well, you could always learn how ... it's just code.

[BoltBait]

If only there was a tutorial on the basics of changing a codelab script (with an input or two) into an effect DLL.

I don't even know where to begin. Besides the compiler (which one?) what else do I need on the system in order to make an Effect DLL?

What kind of project should it be? etc.

I know my questions sound pretty basic, but all the C# coding I do is for the web.

Yeah, but your lightyears ahead of me.

That may be... but that still doesn't mean I can do what you want.

[barkbark00]

Thats ok. Maybe someone else can do it then.

None of those are very difficult problems to figure out. Try writing an effect from scratch. Dissect the CodeLab source code and project files -- it's just an effect plugin itself. Look at the source code for the effects that are built-in to Paint.NET. Once you do that, you have all the pieces you need.

Hey BoltBait,

After writing my Cloud Effect, I have started writing up my development process... I'm still working on it, but it might be a good place for you to start. I have created a Project Template in Visual Studio 2005 that might be a good starting place...

Not having looked at the code(Rectangular to Polar Conversion) would it be easy to just reverse it?

Hey Sepcot, a few notes about your template:

1) Please make the default namespace something other than PaintDotNet.Effects. This is generally the namespace for effects that are built-in to Paint.NET, or that the Paint.NET team has released. Plugins authors should have their own namespace ... like maybe BoltBait.PdnEffects or something.

2) The line of code for, "if (selectionRegion.Visible(x, y))" is redundant. The 'rois' parameter only contains rectangles that are within the selected region (or the entire canvas if there is no selection).

* As an aside: the effect must only render to the areas in dstArgs that are designated by the Rectangles in the 'rois' array that are within the range [startIndex, startIndex+length-1]. This is an absolute requirement. Drawing anywhere else will lead to undefined behavior and may cause children to weep fiercely. You can read from any pixels in srcArgs however.

3) System.Data and System.Xml are not required references. (afaik)

Otherwise, cool stuff.

[BoltBait]

cool stuff.

Agreed.

Thanks! Maybe I'll give it a go.
