Add 'maintain aspect ratio' modifier keybind for selection resize while dragging. #586

Open Flightkick opened 10 months ago

Flightkick commented 10 months ago

Description AFAIK, there's no modifier to keep the aspect ratio locked while resizing a selected area using mouse dragging. It would be nice if this was possible, this makes it easier to align layers without distorting ratios.

In Paint.NET this is achieved by holding down the Shift key while dragging.

For the Move Selected Pixels tool, holding Ctrl + Shift should keep the aspect ratio For the rectangle select tool, Shift only constrains to a square so this would be something to keep in mind when making the changes for #585

@cameronwhite Ah thanks, glad this is supported. Though as Pinta seems to be heavily inspired by Paint.NET, is there any reason for the discrepancy between keybinds (Shift v.s. Ctrl + Shift)?

Also, I haven't been able to find any documentation regarding this behavior, which may be nice to add.

Thanks again!

I don't think it was really intended to be different, but Ctrl is used to activate scaling in the Move Selected Pixels tool because it doesn't have any handles to use for scaling (as suggested in #585)

Also, I haven't been able to find any documentation regarding this behavior, which may be nice to add.

The hotkeys for a particular tool are in the tooltip if you hover over the tool in the tools panel, but the Move Selected Pixels tool doesn't seem to mention using Shift to constrain the scaling
