easy proportional cropping workflow?

Post by steve02476 »

My apologies, I'm a dummy at Graphic Converter and I'm trying to see if I can use Graphic Converter for a particular workflow I do in Photoshop (where I'm also a dummy but I know how to do this one workflow).

I have to crop a lot of pictures to be 600 x by 200 y dimensions. The originals are all sizes. In Photoshop I use the crop tool, set it to 600 x 200, and then I can move the resulting selection area all around the photo and I can also easily enlarge or shrink the selection but it always automatically keeps the correct proportions. When I decide the cropping area is the correct size and location I just hit "crop" and it's done...

What would be a similar workflow in GraphicConverter? I've experimented and looked at the manual but i just don't get it. Probably my poor grasp of the terminology...

Yes, this is supported.

Double click the selection tool:

Now just create the selection and resize it with the corners.
You can move the selection rectangle without the content by holding option+command keys.

Press return to crop and scale to the size.

Interesting! Thanks so much.

It's too bad the non-corner "handles" (is that the right name?) are still there, so I can accidentally grab on one and ruin the proportions, but I can try to be careful!

Also, it's too bad I need to use option+command to move the selection without causing a problem, but thank the heavens for command-Z.

But the part I'm really not sure about is that I must specify the resolution. In my workflow, I don't want to change the resolution, I only want to crop the image. So I guess I need to figure out the image's resolution first, and then type it in the resolution field, so I don't end up with any unwanted resolution change? Or is there a better way?

The resolution is only virtual value that is written to the file.

You change the pixels already with the scaling to the desired size.

Thanks for the info, but I'm sorry I'm not clearly understanding something.

Say I open a massive square image, 12000 by 12000 pixels. I know I want to crop a 3 x 2 rectangle out of it, visually, to get the best part. So when I start the cropping tool, I put in 3 for x and 2 for y. (I certainly don't want 3 pixels by 2 pixels, but that gives me the right proportion!) I then draw my selection to approximately where I want it, and then use the corner "thumbs" to adjust its size while keeping the 3x2 proportions, and move it using option+command. When I'm happy with the size and placement of the selection rectangle, I hit <enter>.

But when I do that, the resulting image is in fact 3 x 2 pixels - useless!

The tool does in fact say "crop and scale" - but I don't want to do any scaling at all, only cropping. If my original image is 12000 pixels square, and I draw a 3x2 rectangle on it that takes the entire width for example then I expect the resulting image to be 12000 pixels in x and 8000 pixels in y (if my math is right, but you get the point). If I use the Crop tool as you explain I think I would have to type in 12000 and 8000 to get it to work right - but then if I decide to make a rectangle that was actually only halfway across, there would be scaling involved also.

I can absolutely see where crop & scale as a single operation would be useful for many - but it doesn't seem like it works for me, when I ONLY want proportional cropping with no scaling at all? But maybe I'm missing an obvious step, that is a specialty of mine...

The shown function is only to crop a special ratio and scale to a special size.

Just use the aspect ratio popup in the toolbox at the bottom if you simple want to define a custom aspect ratio. Now cropping with return will do no scaling - just crop as usual (if you uncheck the option in the selection option - which is off by default).

Thanks so much for your help and patience. The very bottom part of the Tools Palette, I guess is the Aspect Ratio for Selection tool - I hadn't realized that was there.

At first it was creating a weirdly-proportioned shape but then I restored my selection preferences back to default, now it does exactly what I wanted, as long as I remember to only resize the selection using the corner handles and to move it using option-command plus dragging.

Thanks!!!!!!! :D

PS: Just bought a license for v11 after many months of "testing" -- really appreciate your support here.
