Help obtaining a specific texture effect

[fmw42]

Try this.

convert 1RaOUW.jpg \(tile.png -write mpr:tile +delete -clone 0 -tile mpr:tile -draw "color 0,0 reset" \) \
-compose modulate -define compose:args=10 -composite 1test.png

Slightly more refined, using some tricky distortion viewport handling to avoid much of the hassle of draw and mpr usage.

Code: Select all

convert 1RaOUW.jpg  -set option:distort:viewport %G \( rose: -virtual-pixel tile -filter point  -distort SRT 0 \)
-compose modulate -define compose:args=10 -composite test.png

Note the viewport global must be set outside the parenthesis, to set an output image size the same size as the input image. NOTE you can even add +x+y to the viewport setting to 'roll' the tile, or use the the distortion to rotate or otherwise modify the tile (remove -filter point is you want to do that!)
