[Bug 246332] New: Show Resulting File Size in Save Dialog

https://bugs.kde.org/show_bug.cgi?id=246332

           Summary: Show Resulting File Size in Save Dialog
           Product: digikam
           Version: 1.2.0
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: Image Editor
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           1.2.0 (using KDE 4.4.4)
OS:                Linux

When saving as a JPG file, it would be extremely useful to know how big a file
will be as quality settings are adjusted, similar to what GIMP offers. Many web
sites have a file size limit for uploads, and the only reason I resize and
re-save images is to be under that limit. It's aggravating to have to save over
and over with different quality settings until I get it right.

Reproducible: Always

Steps to Reproduce:
Try saving a file as a JPEG

Actual Results:  
No expected file size displayed anywhere

Expected Results:  
An expected file size displayed somewhere

How does the Gimp implement that? Is it byte exact or a guess?
I dont see a way to know the file size before saving.

It's byte-exact. In the save dialog, there's an option to "Show preview in
image window". When that option is clicked, the image is temporarily saved and
its result is displayed in the image window, so I can see what the final JPG
file will look like (compression artifacts and all) as I change JPG options.
After every change, the resulting file size is recalculated. If the file is too
large (ie. 20+ megapixels), then his option is a bit slow so I turn it off. But
at that point, I don't really care about file size anyways.

This ability to see file size and resulting image is extremely convenient. If
Digikam could do it, I'd never need to re-open the files in Gimp just to
re-save to the right file size.
