Plugins and the Canvas


Recommended Posts

Is there some sort of restriction in Paint.NET that restricts the folks creating plugins from permitting the plugins to interact or function directly on the canvas/layer?

For instance the smudge and liquify (and others) open another window where you make your adjustments. The reason why I ask is this results in doing some things blindly because you can't see the rest of the canvas. I think some of these plugins will be so much more effective (especially with the recent addition of grid warping) if you can do some of these things on the canvas so you can shape images/textures to follow contours, but this is nearly impossible without doing so with several blind attempts.

Hi Jim,

Have you tried copying the (flattened version) of the underlying image to the clipboard. Then, when in gridwarp or liquify, right click the checkerboard pattern and and choose background from clipboard.

Hope that's what you meant?

Plugins have many restrictions regarding layers - look in the developers central thread - but I think Pyro has found a clever soloution here.

As an example, I was hoping to use the grid warping to reshape a texture that would match an object on the background. Let us say that for example, I wanted to use tree bark and reshape and contour it match a picture of my face/head. Areas toward the center of the face would need to be pulled in towards the nose for example and other areas around other features. The texture would need to be manipulated separately, but as I'm doing so need to see the canvas so I know where I'm at.

EDIT:

I've tried getting this effect w/alpha displacement, but I was unsuccessful. But either the liquify or grid warping should be effective as well if seeing the canvas were possible while trying to manipulate the texture layer.

I'm sure you can do this!

1. Experiment with the texture layer having a transparent border and using the method I described above to show the background.

Then when you warp the texture it will reveal the background outline at least.

2. make a 'grid' with a transparent background. Warp this to fit the face image (again copied to clipboard and set as background).

This should make it possible to see most of the underlying image.

Save the 'Mesh'.

Run it again with the desired texture and use the previously created & saved Mesh.

In both cases you also want to use the tone from the object to shade the warped texture layer to give an impression of depth.

I've just tried lowering the opacity of the layer to be warped (using BB's transparency adjustment).

Then you can see the background better whilst warping.

When finished use the 'transparency' adjustment (plug-in), to reset to opaque.

And thank you Pyro for the brilliant plugins!

(would it be within the plugin rules to access the layer transparency setting or make it adjustable within the plugin?)

I've toyed with your suggestion, I think it's gonna work! Thank you for your help and also to all you folks who've made these plugins, thanx again!

This is gonna really open up a whole new world of possibilities now that I believe I'm on the right track...!
