Pinch to zoom about drawio-desktop HOT 16 CLOSED

I tried CMD on Mac and I did not notice any difference in zoom speed with pinch gesture.
CTRL-NUMPAD + and - dont work on mac as there is no separate NUMPAD.
If there could be a keyboard shortcut implemented for Mac with slow zoom.. 1 pt at a time, it would be great.

Hey All,
can we re-open this? The issue still persists and zooming via pinch gesture or option+scroll on touchpads is way too sensitive and almost unusable.
Thank you very much.
Best regards, Flo.

There is a JSON config option, btw, in case that was missed:

{
  "zoomFactor": 1.05
}

I would like to see this implemented for Windows 10 machines with touchscreens. It is a really intuitive gesture that, right now, just jumps the contents of the main panel back and forth in a jittery manner.

Hold down the Cmd key while using the pinch gesture. As you can see, the problem is the sensitivity of the touchpad (event is handled here). We have the same problem in the webapp. Feel free to submit a PR. What might be a condition for touchpad vs. mousewheel zoom?

Thanks, that works (modulo sensitivity, as you say).

Can you elaborate on what you mean by "condition"?

from drawio-desktop.

Condition to check if it's a touchpad pinch gesture or a real mousewheel event (didn't have time to look at the event details, but I think last time I checked it was difficult to tell them apart).

Pinch to zoom on trackpad works now with acceptable sensitivity.
If there is still an issue, let us know to re-open

Hey Team,
thx for your hard work you put into this.

Unfortunately CMD doesn't help. Zooming using CMD + scroll / "mouse wheel" (Apple Magic Mouse, which is basically a touch pad) and CMD or option key doesn't make a difference in sensitivity. Scrolling horizontally/vertically through the canvas is damn smooth. I recorded video and will attach it.

Zooming via trackpad and pinch 'n' zoom gesture is exactly the same.

Any workarounds or ideas how to fix this.

Thx a lot and best regards, Flo.

Hey everyone, great program.

On a Mac the zoom is still too sensitive for my taste. It just seems out of sync compared to normal movement speed. Can there be an option set to slow it down, or a faceted zoom with a slight delay?

Just my 2 cents. Thx

from drawio-desktop.

We're unable to adjust this further. As mentioned, we cannot detect the difference between mouse wheel and trackpad. We'll re-open if someone provides the means to do this in this thread.

Could we simply add ability to tune sensitivity?
Hence you don't need to "detect" mouse wheel or trackpad, but user can simply adjust the sensitivity according to the needs?

Also, I think pinch zoom function should be non-linear or should include acceleration factor. I wanted to offer help, but then I realized I could simply clone the project and try out the suggestion myself ;)

I just wanted to suggest the same.
Setting a sensitivity level would solve the issue or some techniques which smooth line based scrolling.
The issue is not only related to pinch gestures. It’s also almost unusable when scrolling with magic mouse, Logitech MX Mastere 3, etc.

it only works ok with cheap mice with legacy line based scrolling

Yup, makes sense - jgraph/drawio#2469

on App, Extras - Configuration, put that json config works. smooth like baby's ass

just tried it on linux (with gnome wayland).
Touchpad pinch to zoom works fine,
but with touchscreen - pinch is just doing rectangular selection.
