I think the detail, what is all about is, that he wants a drag drop operation for the crop rectangle to be limited to the rotated image bounds, so that it is not possible to drag a crop bounding corner outside of the image content. This way the user can adjust as he wishes and be ensured that no empty parts appear in the result image unintentionally.
Hello again, Oliver - - I’m taking a “second bite” at this !
I was making a rotation + crop adjustment myself, just a minute ago - when I noticed something that may be causing you to think that your requirement is not already possible …
To make the crop adjustment (as you describe), you first need to click on the Crop tool … and you can do so even before you close the Horizon or Perspective tool (whichever it was that you were using to cause the image to rotate) … then the cropping adjustment you describe, and that I demonstrate above, is easily obtainable.
That would be fine as an optional setting - But I, for one, would not like to see this as standard functionality … 'cos, occasionally, I find I can get away with a sliver of “empty content” beyond the true edge of the image - as this can be handy when I’m juggling between degree of image rotation versus retaining key elements of the image.
even if you have a very precise positioning, you need to view both edges with 100% zoom, and although I have a 3440x1440 monitor, both edges usually don’t fit the screen, so I have to pan back and forth to get both corners exactly at the image border.
Try the same task in Photoshop: There is the requested switch / option, and you simply push the crop area to the image limit even with 25% zoom quickly.
Thanks for agreeing on the necessity / usefulness.
It is simply not possible to hit the border reliably with single pixel precision if you don’t work with 100% zoom. Therefore (unless you have a 40" 4k screen and/or very small crops) you either let some safety margin or you get black triangles sometimes.
It’s really boring that we need to take extreme care to not crop outside of the image area. Since PL already knows the limits (and is able to display them!), it should really as well take care of them. Of course this needs to be configurable (on/off).
This does not only apply to rotated images, but to perspective corrections as well.
I consider this as a missing core function, which IMHO should have significantly higher priority than (i.e.) DAM…
Just recently I was working on a set of aerial images where the weather was turbulent so I had to adjust a lot of them, and often I needed also to push the crop area to the left or the right and It was no fun.
I agree it’s amazing some of these really simple improvements are still not implemented.
It’s very simple. Add a check box called “constrain to picture limits” and make it checked by default for new images. I can see very few practical cases (but more than zero) where I would want a crop that included the black sliver where there was no picture previously.
