Enhancement Request: Catalyst Crop Resizing Experience

rickshane commented 6 months ago

In Image editing apps, the Crop Resizing UX is typically different on a Mac than on an iOS device.

On a Mac:

The tool bar is hidden when a click is issued anywhere around the crop box within a fixed tolerance margin (inside and outside the frame).
There are cursor rectangles in the view that change the cursor depending on the region of the crop frame being hit; for top, bottom, left, and right there is one type of cursor that is transformed based on which region. For the four corners: upper left, upper right, lower left, lower right, there is another cursor image that is transformed depending on the region being clicked.
As soon as touches end and the crop resize animation finishes, then the toolbar shows again.

Here is Apple Reference page which discusses how to set system cursors in Catalyst:

It looks like cursor rects as used in AppKit are not supported in Catalyst. This will probably need to get solved with a Hover Gesture Recognizer:
