# resynth
|
|
|
|
resynthesis is the process of taking a source texture and
|
|
creating similar (oft tiling) textures based on it.
|
|
|
|
resynth is a C rewrite of the original resynthesizer by [Paul Harrison.][pfh]
|
|
it does not require GIMP to function; just feed it image paths and it will save copies.
|
|
however, this program lacks the patching (masking) and texture transfer abilities of the original plugin.
|
|
|
|
resynth produces [tiling images like those seen here.][examples]

## help
|
|
|
|
```
|
|
usage:
|
|
-a --autism
|
|
sensitivity to outliers
|
|
range: [0,256]; default: 32
|
|
-N --neighbors
|
|
points to use when sampling
|
|
range: [0,1024]; default: 29
|
|
-r --radius
|
|
square neighborhood, always odd
|
|
range: [0,32]; default: [n/a]
|
|
-R --circle-radius
|
|
circle neighborhood radius
|
|
range: [1,128]; default: [n/a]
|
|
-M --tries
|
|
random points added to candidates
|
|
range: [0,65536]; default: 192
|
|
-p --polish
|
|
extra iterations
|
|
range: [0,9]; default: 0
|
|
-m --magic
|
|
magic constant, affects iterations
|
|
range: [0,255]; default: 192
|
|
-s --scale
|
|
output size multiplier; negative values set width and height
|
|
range: [-8192,32]; default: 1
|
|
-S --seed
|
|
initial RNG value
|
|
default: 0 [time(0)]
|
|
{files...}
|
|
image files to open, resynthesize, and save as {filename}.resynth.png
|
|
required default: [none]
|
|
```
|
|
|
|
apologies for the `radius`, `circle-radius`, and `polish` parameters.
|
|
they should be properly described or removed.
