GmicSharpPdn Beta (2020-07-14)

[null54]

This is an extension of my gmic-sharp library that allows it to be used by Paint.NET Effects.

It allows G'MIC commands to be applied to a Paint.NET Surface.

The gmic-sharp-pdn-example Effect plugin demonstrates the use of the gmic-sharp-pdn library.

It also provides an example of how to use ILMerge when building Paint.NET plugins.

 

While this topic is primarily intended for plugin developers, users can download the example plugin, which wraps the G'MIC water command.

An example of the effect can be can be seen on the deformations page of the G'MIC filter gallery, https://gmic.eu/gallery/deformations.shtml.

Given how simple the water example is, I think I feel confident about no longer needing to manually convert gmic code into c#. I will have to try this.

 

I do have only two question though.

1) Does gmic command "to $_host" shows paintdotnet on canvas?

2) Is it possible to pass on clipboard image and use [1]? You noted [0] is a layer in gmic.

No, it currently shows "gmic-sharp".

I would have to change the gmic-sharp libraries to allow custom host strings.

Yes, I will add a commented out block of clipboard code to the example.

You should also be able to use the IndirectUI file picker control.

One more question. What if I want a different view and/or avoid affecting the canvas during modifying setting. One example of a G'MIC filter that needs both of them is the Non-Isometric RPG Tiler (Interactive). I believe that you need to create an auxiliary surface to render the effect, and then send it to a preview window within the GUI. Rendering the end result after the interactive window is what comes after the prerender. Right?

PreRender is performed once. Subsequently Render is called multiple times, each call passing a "strip" of pixels (the so-called ROI or Rectangle of Interest). 

 

You might find this discussion helpful if you're considering utilizing a separate work surface: https://forums.getpaint.net/topic/22086-roi-and-shared-state-threading/

You would have to use a Windows Forms dialog if you what to control what settings cause Paint.NET to start rendering its preview on the canvas.
