a Problem with Ink Sketch Effect

Recommended Posts

So I have an image in Paint.net that is just textures on transparent background, and I wanted it to look like an ink sketch (you know, the outlines and all) but when I use the effect, it fills the transparent places all black. All I need is for the ink sketch effect to leave those transparent places untouched.

The reason for the edit is to give a little more detail about what I want the output to be.

Hello @Just Another User and Welcome :)

 

Why don't you try merging the texture (with the transparent background) onto a white layer and flatten.  Then try Ink sketch again :)

Alternatively - and this all depends on the textures mentioned - you could use the magic wand >>> click on a transparent part >>> Ctrl + I to invert the selection >>> Run Ink Sketch

 

You may have to play with the magic wand settings and it may or may not work out.  It does on more solid objects

Failing that ... you could try some of the G'Mic  filters.  They support transparency when running an effect.

Unlike Ink Sketch; Ink Sketch + does not alter background transparency!

The ink drawing effect looks best to me when the 'blue' box is checked.

Or, instead, use BoltBait's Paste Alpha plugin. (I try to use the Magic Wand as seldom as possible for this kind of thing.)

 

Though it's hard to tell the best plan without seeing the image you want to modify, one approach is:

Copy the image to the clipboard.

Add a white layer underneath.

Merge down, so your original image is now on a white background instead of transparent.

Run Ink Sketch.

Run Paste Alpha, with the Alpha Source set to Clipboard alpha.

 

EDIT: Though HyReZ's suggestion of using Ink Sketch+ is probably the best way to go.

Live and learn # 2 ... that's a great tip.  I've never thought of that.
