[Bug 224245] New: Each image editor plugin should remember the zoom ratio

https://bugs.kde.org/show_bug.cgi?id=224245

           Summary: Each image editor plugin should remember the zoom
                    ratio
           Product: digikam
           Version: unspecified
          Platform: unspecified
        OS/Version: unspecified
            Status: NEW
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:            (using KDE 4.3.4)

For some filters (sharpening, noise reduction) one will often want to preview
at 100%. Thanks to Gilles, it is now possible with 1.1.0 !
I think it would be even better if each plugin could save the zoom ratio, so
that next time you open a plugin you get the same zoom ratio as the last time
the plugin was used.
By the way, in my opinion, some plugins should have a default of 100%:
sharpening, noise reduction and maybe inpainting and restoration.

I'm not really favorable for that. this will increase complexity...

Look the new behavior, ask with another bugzilla entry : the zoom ratio used in
editor canvas must be the passed to editor tool preview.

I will be more precise here :

- zoom is synchronized.
- pan position is synchronized.

... when user go in editor tool and go out editor tool. this is fully
transparent for end user : it think thank same widget is used to render image.

I would also argue that all tools separated from the main view need a different
zoom and pan position. I normally view images in "fit to screen" mode for doing
global editing like cropping or color changes whereas sharpening or noise
reduction needs to be done on zoomed versions and it's really annoying that you
always have to do the same canonical "5 times press +" when entering the
sharpening tool.

Perhaps you have don't understand me :

- load an image to editor.
- zoom to a dedicated region. image still in canvas.
- load Refocus tool : region and zoom still used as well.
- change zoom level in tool, or pan image.
- apply Refocus and go back to canvas.
- Canvas use zoom and position set in Refocus.

I recommend to zoom/pan in image in canvas, select right region, and use tool.
For me it's more intuitive and natural to force a zoom level for each tool.

Also, i like this behavior : canvas and editor tool preview are synchronized.
This will be transparent for end user : canvas and preview sound like the same
widget.

But I don't want to zoom in first in the canvas only to zoom out again after
having applied the filter.

I'd really vote at least for a user option.

It would be nice to have other opinions about this. Andi, Marcel ?

As a user, I think I'd like to have the same zoom ratios in all tools and
canvas.
If I zoom in canvas and start a tool, the tool uses the adjusted zoom ratio. If
I zoom in or out while using the tool, and exit the tool, the canvas should
take the zoom level from the tool.

For me it is also more natural when canvas and tools act transparent to each
other in case of zoom and view area, so current svn behaviour is fine for me
...

I'm agree with Jens, and it's what i have implemented by default.

I'm not favorable to add another option in setup, only for this behavior.

I would to hear more viewpoints here. Marcel ?

Following reports here, I will let's the current zoom behavior between editor
