I have placed a large PDF in InDesign, as below:
I want to shrink the frame so that only a section of the content will be visible, but without changing the size of the content in any way, so that I end up with something like this:
How can I do this? The InDesign help page says
To move a frame without moving its content, click the frame using the Selection tool, switch to the Direct Selection tool, and then drag the center point.
However, I can't figure out how to scale the frame without scaling or skewing the image.
