A new user filter

Retrobatch

Not sure if this is possible but I use a filter almost everyday in photoshop called “Oil Paint”. It basically converts the image into the appearance of a oil painting. It has the following settings.

Stylization

Adjusts the style of the strokes, ranging from a daubed look at 0 to smooth strokes at 10

Cleanliness

Adjusts the length of the strokes, ranging from shortest & choppiest at 0 to longest & fluid at 10

Scale

Adjusts the relief or apparent thickness of the paint, moving from a thin coat at 0 to a thick coat, giving luscious Vincent van Gogh-style paint globs, at 10

Bristle Detail

Adjusts how much of the paintbrush-hair indentation is apparent, moving from soft at 0 to leaving strong grooves at 10

It would be awesome if this was available at some point or even better, a new type of filter that could incorporate a number of settings like these that would be in one filter…. kind of like a custom/user filter. Options that could morph, twist, etc all in one filter. Maybe they could be saved and user named? — Maybe I’m getting ahead of myself.

Hi!

One approach is to play with ImageMagick settings. Install it via Homebrew (brew.sh)!

Then make a Shell Script node and see if these settings might be what you are looking for, and adjust or fully refactor as needed!

#!/bin/bash

imagePath="${@: -1}"
fileName=`basename "$imagePath"`
outputPath="/tmp/oilpaint_$fileName"

# Parameters (adjust these values)
STYLIZATION=5    # 0-10 (maps to paint radius)
CLEANLINESS=7    # 0-10 (affects smoothing)
SCALE=3          # 0-10 (thickness effect)
BRISTLE=2        # 0-10 (texture detail)

# Convert parameters to ImageMagick values
PAINT_RADIUS=$STYLIZATION
BLUR_SIGMA=$(echo "scale=2; $CLEANLINESS / 10" | bc)
EMBOSS_RADIUS=$(echo "scale=2; $SCALE / 2" | bc)

/opt/homebrew/bin/convert "$imagePath" \
    -paint $PAINT_RADIUS \
    -blur 0x$BLUR_SIGMA \
    -emboss $EMBOSS_RADIUS \
    -normalize \
    "$outputPath"

echo "outputImagePath: $outputPath"

See the attached before & after image.

Hello @redsei ,

There’s nothing like that in Acorn right now, though it does sound like something that a maybe a generative model would be able to do someday. If Apple doesn’t bring those models to the Mac sometime soon, I’ll probably add an optional 3rd party integration to Acorn to make these kind of things possibly (completely optional of course!)
