I do a fair amount of cropping. I want top be able to crop to a defined print size, so 4 inches by 5 inches, 5x7, 8x10, 8x12, and so on.

Currently when I display the "Selection Info" it gives the the corners x/y for the selection, the selection width/height plus the percentage of the whole image, but it not does not show the ratio between the width/height.

It would be really helpfull to have that shown.

The percentage does actually indicate the ratio, but obviously not in the unit you would like to see it.

angle = atan(1/aspect_ratio) where aspect_ratio=x/y

or the other way:

apect_ratio = 1/tan(angle)

For instance, the angle of your 8x10 is atan(10/8) = 51.34 degrees

I will consider adding display of the aspect ratio in a future version!

BTW, the aspect ratio of 8x10 is 4:5. The aspect ratio of 8x12 is 2:3. This is what PMView would display. It would never display 8:12 because that's not a normal form.

I'd also like the option to 'lock' the aspect ration. For example, most often we get prints done in 6" x 4" - so when cropping photos would like to 'lock' the expansion of the selection dialog to this ratio to save fiddling smile.gif

Cheers,

Paul.

Yes. that would be great. This is exactly the feature, that I am missing in PMview.
