Description andydecleyre 2016-06-27 16:24:54 UTC

Gwenview 16.04.2 fails to enlarge SVGs, as attempted either by toggling the "Fit" button or selecting "Autofit each image" and "Enlarge smaller images" in the settings.

Reproducible: Always

Steps to Reproduce:
1. "Autofit each image" and "Enlarge smaller images" in the settings
2. Open an SVG

OR

1. Open an SVG
2. Toggle on the Fit button

Actual Results:  
The SVG is displayed in its "original" small size.

Expected Results:  
The SVG should be enlarged to fit the available space, as is the behavior with other image formats.

I'm using

- Arch Linux
- qt5-imageformats 5.7.0
- kimageformats 5.23.0

I do not have kipi-plugins installed.

Confirmed. I suspect that there are a lot of people who would blow a blood vessel if this behavior were enabled, though...

Why would someone who explicitly turns on auto fit, or someone who deliberately hits the auto fit button, blow a blood vessel if the program were to do what they asked?

Enlarge small SVGs too

Summary:
For images smaller than the viewport at 100% zoom, Gwenview allows to
scale up the image to {nav Fit} the window if {nav Enlarge smaller images}
is checked in the configuration dialog. So far this only worked for
raster-based images, but not for SVGs.

`mEnlargeSmallerImages` is meant to be handled by the abstract base
class `AbstractImageView`, however when f00cef3c0 moved code over there
from `RasterImageView`, it was missed to also adapt `SvgImageView`. This
can be fixed by implementing the missing function.

In addition, a left-over `bool` is removed.
FIXED-IN: 17.12.3

Test Plan:
- Open `icons/hisc-apps-gwenview.svgz`, press {nav Fit}: Small icon shown.
- Check {nav Enlarge smaller images}, press {nav Fit} again: Icon scaled up to fit window.
- Enlarging raster-based images still works fine.
