|
|
Gimp plugin.
|
|
|
|
Create new image having texture synthesized from the selection.
|
|
Works best if selection is natural (fractal).
|
|
Can work with man-made regular texture.
|
|
Works worst with man-made, structured but not regular, symbols.
|
|
Sometimes called rendering a texture.
|
|
|
|
Requires resynthesizer plug-in.

The effect for users:
|
|
Similar to "Fill resynthesized pattern" except:
|
|
- here the arguments are reversed: you select a texture and create a new image
|
|
instead of selecting an area and choosing a pattern.
|
|
- here the result is less random (since Fill resynthesized adds noise.)
|
|
Different from tiling since:
|
|
- seamless and irregular pattern
|
|
|
|
The continuum of randomness versus speed:
|
|
- Filters.Map.Tile is fast but has seams and regular pattern (even if you use "Make Seamless" first.)
|
|
- Filter.Render.Texture a tile followed by tiling is seamless but still has regularity.
|
|
- Filte.Render.Texture an entire image is slower but seamless and moderately irregular.
|
|
- Edit.Fill with resynthesized pattern is slowest but seamless and highly irregular, unpatterned.
|
|
|
|
This filter is not tiling (instead resynthesizing) but makes
|
|
an image that you can then use to tile with especially if
|
|
you choose the option to make the edges suitable for tiling.
|
|
|
|
IN: The selection (or the entire active drawable) is the source of texture and is not changed.
|
|
OUT New image, possibly resized canvas, same scale and resolution.
