Wacom pen usability

[Michael Ezra]

I tend to use Wacom pen much more efficiently than a mouse, which in itself is quite common in image editing.

However, pen usability is crippled here since the early days of RawTherapee. The preview image is not refreshing until pen is entirely lifted from the underlying surface, or a button on the pen is clicked. Essentially, until those two events are detected, the “click” event is not seen as a completed event. In comparison, I use the same pen with Photoshop and numerous other image editing programs, and usage is seamless - the press of the pen is considered a click.

Interestingly, when I start using a pen, I can no longer use a mouse within ART / RT. This is a minor issue, as opposed to the one described above.

This would be a highly welcome fix.

Thank you!

I agree this seems quite annoying. Unfortunately, I don’t have such device, so for now I’m afraid there’s not much I can do about it… I’ll search around and see if this is a known GTK issue, but I can’t promise much.

Thank you for looking into this.

Hi,

what Wacom pen are you using? What OS and GTK version? I just got a cheap wacom one, and on my system (ubuntu 18.04) it seems to work as expected out of the box…

Hi, I am on Win10 Pro x64, Wacom Intuos 3 9”x12” tablet (its old, perhaps >15 years, but works as new still)
I have a newer version of Wacom table (smaller size though) in the storage.. will give that a try

Closing, as wacom tablets should work reasonably well now (at least mine does...) If not, feel free to reopen

Just saw this issue that popped out. I have an Intuos Pro that is onyl 2 y.o., and have a problem with the refresh of the main preview too. When zoomed to 100%, the preview will only refresh after panning once the pen is out/above of the detection “field”. A also I need to keep the pen down to select a combobox entry, while you can do it with 2 clicks witht the mouse.

Not that I’m using the pen tablet for ART, but it was just my 2 cents.

Thanks for the feedback. I only use my wacom to edit the brush mask, and I think it works reasonably well for that (at least under linux). I will check again when using the pen as a more general mouse replacement, something I admit I have never really tried…
