How do I enter an aspect ratio for the crop tool?

Is it possible to save a ratio? I often use A4 or 1.414 (it’s a common, important page format) but I always have to put it back there when I need it.

You can always save it as a preset. For precise DIN ratio figures, consult this page:

Tabelle - Papierformate und Seitengröße - DIN A Maße - Umrechnungstabelle -...

A4 paper measures 297 by 210 mm. This corresponds to a ratio of exactly 99:70
Note that other A paper sizes can differ slightly.

For printing, look at this thread (or any other that deals with it):

The margins dialogs in PL4 print

Is the print window in beta ? [probImprimer_1] ! The values on the margins bear no resemblance to the actual margins as seen in the preview. [probImprimer_2] ! Moving one single margin, the leftmost (as seen, not relative to the photograph) affects the other margins. Again none of this is reflected in the dialogs. No undo/redo, no reset… I did not choose a printer so it so conflict with driver shouldn’t be a factor. Kesako ? Thanks
