Use graphcsmagick to generate images for the kobo forma screensaver mod
Raw
kobo forma
The screensaver mod renders only png images 1:1 to the top-left corner of the screen.
So we need to
- Resize larger images down to the screen resolution (1440x1920)
- Resize smaller images up to the screen resolution
- Composite images centered on top of a canvas sized 1440x1920 - images not exactly 1440x1920 will be centered
- Convert to grayscale
gm.exe mogrify -output-directory kobo -format png -type Grayscale -geometry '1440x1920' -gravity center -extent '1440x1920' *
