Touch SVG Images Often Appear as Black Rectangles

MikeWV · 07-09-2014, 11:39 AM

Since updating my Kobo Touch to firmware 3.3.0, many SVG images appear as black rectangles, i.e., 100% black. It is always the same images, i.e., the images that are rendered 100% black do not randomly change whenever I open a book with SVG images.

Has anyone besides me experienced this problem? Does anyone know what causes it and how to solve the problem?

I haven't encountered it, but if you have an example of a (free) book with this problem then others could test it on their devices.

Does it happen in the epub or kepub reader (or both?)

I neglected to mention that this only happens with kepubs; all of the images display when a book is viewed as an epub.

As requested, I've attached a sample of my book, Chapter 4 and Appendix III, as a plain ePub. Just change the extension to .kepub.epub to view it as a KePub.

What I'm seeing on my Kobo Touch (3.3.0) as a KePub are black rectangles for the following images: Table 4-1, Table A3-2 and a block of formulas one paragraph below A3-2.

You can also see that the firmware is ignoring embedded fonts. When viewed on my Touch as a plain ePub (.epub), I have neither of these problems but the default fonts in the images are obviously inappropriate and rotated text (like Y-axis titles) is scrambled.
