Bug Description

When zooming in / zooming out with "Ctrl +" and "Ctrl -" only the text font size is affected, pictures don't change. Expected behavior: pictures should follow the actual zoom factor as experienced with browsers.

The size of pictures in relation to other zim-contents may be adjusted with the "Edit Properties" dialog or "Ctrl E". Therefore it is easy to set up a reasonable size with respect to text. The ratio of picture size to other contents size should be kept equal therefore.

Use Case:
============
On a presentation it may be necessary to enlarge the displayed contents. But the pictures (diagrams with details) will not enlarge.

Work around:
============
Print page to browser and zoom there. But this adjustment should be made by zim by applying the actual zoom factor (100%, 130%, 85% ...) on pictures as the very last step just before display.

zim 0.60; Ubuntu 14.04

Thanks, Andreas

I would propose to use the "open with" in the context menu to open the image in an external viewer to get more flexibility

Making this "won't fix" as it is intended that the zoom is for the font size. Images will not scale.

Separate from that I do intent to make images flexible adapt full page width

Yes, this is your decision. No problem.
But keep in mind that this behavior is
 a) unexpected and non-intuitive, because zooming in just enlarges the fonts and not the pics (diagrams)
 b) different from behavior of pdf viewers, web browsers and svg editors etc.
If the ratio of image size and context font is bad, you may change the pic width or height
accordingly. But this setting is done only 1 time, maybe for each picture.
In contrast, the factor for zooming in and out is a temporary setting for view time.

Best regards, Andreas

I guess you have a point there. I was thinking of this as "scale font" not "zoom view". But looking at other applications, I find this is an outdated usage.

Still need to think how this would fit.
