Examples

Save single picture to PDF:

$ pictureshow pics/potato.jpg -o potato.pdf
.
Saved 1 picture (1 page) to 'potato.pdf'

Save multiple pictures, four pictures per page (two columns, two rows), set page orientation to landscape:

$ pictureshow -l 2x2 -L vegetables/* -o vegetables
..................................................
Saved 50 pictures (13 pages) to 'vegetables.pdf'

(Please note that if the output filename has no extension specified, .pdf will be appended to it. This only applies for the command line tool.)

You can also save pictures from URLs:

$ pictureshow https://cdn.rebrickable.com/media/thumbs/parts/elements/6136555.jpg/250x250p.jpg https://cdn.rebrickable.com/media/thumbs/parts/elements/4119478.jpg/250x250p.jpg -o carrots
..
Saved 2 pictures (2 pages) to 'carrots.pdf'

But please note that this feature is not tested and depends solely on the underlying reportlab backend.
