Hi Kevin and Diap;
Please, open the attached epub; you'll see an image with a svg filter applied to emulate a metal surface. Now go to Metal_Filter.svg file and where you see
Code:
<feFlood flood-color="red" result="solid_color"/>
change the color "red" for any other color (blue, green, orange, khaki, coral, whatever) and the change is not reflected in Preview Pane, even if I press "Update Preview Window" button. If you open the epub with any of the Sigil's plugin, the change is present. Why Preview Pane is not showing changes in the epub code?
