I did this already. >> What would be very convenient for my use case: Using the keyboard to >> give a size (e.g. 1600x900), and then use the mouse to drag the crop >> rectangle to the appropriate position. > > So far, what I do is set the size via mouse manually once then create a > style with the correct size for other pictures. Oh, that is a nice workflow.

Other software (like Google > Sketchup) has similar features. It would be perfect for me to type it into the aspect ratio slider, exactly the same way as the aspect ratio, but with "x" instead of ":" or "/" to separate the two numbers. > Alternatively, including in the iop module a box showing the position > and another showing the size ?
