To minimize size of the manjaro package and to provide the best experience for our users, we follow these optmization steps for each image:
-
You'll need these packages for the tools used here:
imagemagick,jheadand mozjpeg -
Convert image to JPG if in another format if is a photo, we can accept PNG format if the size is not huge:
mogrify -format jpg <imagefile> -
Scale down image to match 4K (3840x2400) size:
mogrify -resize 3840x <image.jpg> -
If image is still huge in size (above 4MB), check it's quality level:
identify -verbose <image.jpg> | grep 'Image:\|Quality'
If higher than 92, reduce it down:
mogrify -quality 92 <image.jpg> -
Remove all metadata except XMP and comments:
jhead -autorot -de -di -du -c <image.jpg> -
Losslessly optimize images with mozjpeg:
/opt/mozjpeg/bin/jpegtran -optimize -progressive -outfile 'Output.jpg' 'Input.jpg'
After renaming the resulting image to Image_Title_by_Artist format, it is ready for inclusion.
