Missing cover image from book

[cgreening]

See this epub file:

https://sync.luckycloud.de/d/bf3a5b1d14f949b89955/?p=%2FePub&mode=list

Data all looks correct - but no cover image.

Nice one I will test this tomorrow!

Can you try:

git submodule update

or

git submodule update --remote

I'm having some issues with git submodules and getting them to update to the correct commit. The issue with the book is that it contains some invalid utf-8 sequences which was crashing epdiy. Should be fixed in the latest version of epdiy now but for some reason that's not coming through in the git submodule.

[martinberlin]

Sure!

 $ git submodule update --remote
 Submodule path 'lib/epdiy/epdiy': checked out '8b4302a6a650a5c228520c100b862aba60978c2c'

If I see this correctly is hanging at this line:

  while ((c = next_cp((const uint8_t **)&string))) {   // <-- HERE
    get_char_bounds(font, c, &temp_x, &temp_y, &minx, &miny, &maxx, &maxy, &props);
  }

But that's strange before it didn't hang with this book on font.c, just the cover was missing.

[martinberlin]

Awesome, now it works and the cover of this book is displayed properly, thanks!!!

I really need to try and understand git submodules better.
