[Bug 184541] Resize error when sharpening in image editor

Bugzilla from rbr28@yahoo.com
https://bugs.kde.org/show_bug.cgi?id=184541

           Summary: Resize error when sharpening in image editor
           Product: digikam
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           10.0 rc2 (using KDE 4.2.0)
OS:                Linux
Installed from:    Gentoo Packages

I've tried to narrow this down and the error is definitely reproducible on
different machines.  Here are the steps that will hopefully reproduce the
error.

Use a RAW image with a portrait orientation...the error does not seem to occur
as often with landscape orientation images, but I have had the error with all
images.
Choose to edit the image.
Choose Transform - Resize...use 25% for the resize (the resize value does not
seem to be important).
Then choose to Enhance - Sharpen, using Refocus.
In the new preview the image will be zoomed excessively...maybe 125%, maybe
175%.  This obviously is not useful for sharpening which should be your last
step in workflow.  Using the zoom out buttons, the image cannot be zoomed out
even to 100%.
This error does not occur 100% of the time, but it does occur very often.  I
have been able to work around it by zooming out on the original image to a low
value, before choosing to sharpen.  For example, if I zoom out to maybe just
25%, the zoomed value when I sharpen may only be 75% and I can actually then
zoom in on the preview to 100%.  At some point the image will always be
previewed above 100% in the sharpening preview, and it cannot be zoomed out to
a lower value.  I don't think this is the intended behavior.

Confirmed that problem occurs regardless of sharpening technique used.  Seems
to be a preview problem, but it doesn't occur in preview when using some other
tools.

I think this can be simplified like this:

Edit any photo for opening (for example the good old 0-8bits-photo.png).
Choose Enhance->Sharpen.
1)Click once on Zoom Out.
  => Zoom out is disabled, and the right hand part of the preview disappears
2)Or: change the preview mode, e.g. from horizontal to vertical side-by-side
preview, and the second part of the preview disappears.

Gilles, any idea?

I noticed this problem is still present in .10.0 final release with KDE 4.2.1.
What Marcel said is true, but I think it's more than that.  Why would the
preview on sharpening immediately go to something greater than 100% by default?
 Usually as soon as I select sharpen the view goes to something like 160-180%
which is not at all helpful for judging the effect of sharpening.  After that,
as Marcel described, it's not possible to zoom back out.

Thanks,
Vern

Is this bug being worked on or do I need to resubmit it for .10.0?

Trying to reproduce with 1.0-beta2 (current trunk) the testcase I described in
#2, it seems to be solved for me.
The Sharpen filter start with fit-to-window zoom now. It feels a bit clumsy as
there is no automatic preview creation now but you have to press "Try",
otherwise there is white background visible, but this is probably intentional
and not the issue here.
So please try the latest 1.0 beta to see if there is a problem remaining.

The primary problem that I reported on this ticket is resolved in 1.0 beta2.  I
noticed other related problems, but I'm not sure if I should report them here
or in a separate ticket so I'll try here first.

Whether I choose fit to window or not does not affect the resize in 1.0 beta2.
I can resize using the zoom in and zoom out buttons and that was my number one
concern, mostly because a 100% preview is necessary for the best sharpening.

Here are the possible new bugs, although I'm not 100% sure they are bugs.

In b2, I cannot click on the percentage for the preview and change it (the down
arrow in that box used to be clickable if I remember right).  Not a big deal
since preview size can be changed with zoom in or zoom out.

In b2, I cannot select/deselect 'fit to window' after I choose to sharpen.
Whatever was set in the initial preview window when I choose edit is carried
over to the window that opens up after I choose enhance/sharpen, but the
setting cannot be changed.  This is insignificant to me, but I thought I'd
report it in case it is a bug.

Zoom to 100% (via menu or keyboard shortcut) works fine in the initial edit
window, but again it does not work in the window that opens after choosing
enhance and sharpen.  I thought this might be the expected behavior and not a
bug, but wanted to make sure.

Those are all insignificant compared to the initial bug reported.  Thanks so
much for taking care of that one!
