maemo.org - Talk - Sailfish Silica pattern for your backgrounds

and this

Code:

composite -compose Screen -tile jolla_pyramid.png wallpaper.jpg output.jpg

will silica-fy your wallpapers on the fly, right on your N9

If composite returns command not found type

Code:

apt-get install imagemagick

as root

you will need Morpog's file in the working directory

A better version according to my taste:

1. darken Morpog's image (you only need to do this once)

Code:

convert jolla_pyramid.png -modulate 50 jolla_pyramid_dark.png

2. blur your wallpaper

Code:

convert your_image.jpeg -blur 0x4 temp.jpg

3. darken it

Code:

mogrify -modulate 80 temp.jpg

4. compose the images

Code:

composite -compose Screen -tile jolla_pyramid_dark.png temp.jpg test.jpg

5. Delete temporary image

Code:

rm temp.jpg

you can try with Soft_Light or Multiply instead of Screen for alternate effects

full code, assuming darkened jolla_pyramid

Code:

#!/bin/sh

convert "$1" -blur 0x4 /tmp/img_temp.jpg

mogrify -modulate 80 /tmp/img_temp.jpg

composite -compose Screen -tile jolla_pyramid_dark.png /tmp/img_temp.jpg  "jollified-$1"

rm /tmp/img_temp.jpg
