4 additional handles to VUI: Top, Bottom, Left, and Right

TRA · August 5, 2021, 8:15pm

This patch will add 4 more handles to the VUI for filters such as

Size, Position and Rotate
Text: Simple
Text: Rich
Crop: Rectangle
Spot Remover
Gradient

in version 21.06.29 and later. It should work in 20.10.31 and later too, but certainly not in any previous versions.

OBS has those, Krita has those, and probably a lot more software do too, so the use should be intuitive.
It allows you to change one of the four lines without changing the properties of most of other lines.

Note that these 4 handles are invisible under Fill mode in Size, Position and Rotate filter.

For immediate tests and uses

Go to your Shotcut installation location and find RectangleControl.qml
It is located
For Windows users:
Program Files\Shotcut\share\shotcut\qml\modules\Shotcut\Controls
I don’t know MacOS or Linux, but from what I can tell
For MacOS users:
Applications>Shotcut.app>Contents>Resources>shotcut>qml>modules>Shotcut>Controls
For Linux users:
Shotcut.app > share > shotcut > qml > modules > Shotcut >Controls
Rename RectangleControl.qml to something like RectangleControl.qmlOriginal, so that there is a backup.
Download the following file and paste it to the location above.
RectangleControl.qml (27.7 KB)
Launch Shotcut.

This is TRA from the forum. This patch will add 4 more handles to the VUI. Th…e only file to be modified is RectangleControl.qml. I've been using this for a long time on my local installation, and it's been very useful for fine adjustment of the rectangle. I think it's time to share it. The main part of this patch is `topHandle`, `bottomHandle`, `leftHandle`, and `rightHandle` which are basically copy-pastes of `topLeftHandle`. Literally the rest of them are inserted into the existing code to adjust the new four handles and sometimes the existing handles because they are misaligned. Main modifications to the 4 copy-pastes are: - `x` and `y` calculations in `onPositionChanged`. - when `aspectRatio !== 0.0`, all 4 handles become invisible. This is because there is no intuitive way the rectangle's four corners should move when the bottom handle is moved, for example. This is also a quick visual clue to what mode Size, Position and Rotate filter is in. - `if (aspectRatio !== 0.0)` clauses in `onPositionChanged` are erased due to the above reason. These 4 handles are placed between `topLeftHandle` and `topRightHandle`. This is due to what comes on top of what when VUI is too small. It's easier to restore a rectangle shape from a point shape or line shape with diagonal movements.

I hope to see it merged to the next release 21.08.

I have been using this for a long time on my local installation, so there shouldn’t be an appearent bug with it.
It is basically copying Rectangle id:topLeftHandle four times, restricting x and y movements, and sticking them between topLeftHandle and topRightHandle.
The only downside I can think of this patch is that it becomes slightly difficult to grab the center handle. I think the upside outweighs the downside.

Installé sur version V20.09.27 (OSX)
Semble fonctionner à première vue, à confirmer à l’usage.
Je suis déjà convaincu de son utilité.
Merci pour le partage

Installed on version V20.09.27 (OSX)
It seems to work at first sight, to be confirmed with use.
I am already convinced of its usefulness.
Thanks for sharing

This is amazing! If this starts working for masking and chroma-keying, it would be a game changer!

On version 21.05.18, it’s seems to work except for Size, Position and Rotate

This is normal, in fill mode, the ratio is kept.
It works for me in distord mode
