Check Book can't find images in svg tags

ShellShock · 02-02-2014, 06:45 AM

Is this a bug?

I have this:

Code:

<div>
    <svg xmlns="http://www.w3.org/2000/svg" height="100%" preserveAspectRatio="xMidYMid" version="1.1" viewBox="0 0 402 650" width="100%" xmlns:xlink="http://www.w3.org/1999/xlink">
      <image height="650" width="402" xlink:href="Images/img001.jpg"></image>
    </svg>
</div>

This image displays fine in File Preview, but Check Book complains: "The file OEBPS/images/img001.jpg is not referenced". And also "The linked resource 'Images/img001.jpg' is a directory [OEBPS/maps.html]".

The referencing file is OEBPS/maps.html, and the image file is OEBPS/Images/img001.jpg so the file locations are OK (they must be because File Preview would not work).

OK, I found the problem was due to case sensitivity. The image file is in "OEBPS/images/img001.jpg", but I was linking to "Images/img001.jpg".

Would this be a good candidate for an automatic fix? I.e., change case of links to match physical locations.

Case mismatches are a rather subtle problem. calibre represents the book as files on the filesystem. Therefore case mismatches may or may not be detected, depending on the case sensitivity of the underlying file system. I plan to spend the time someday to make it work right on all filesystems, but for the moment, the fact that it points out *some* error is enough.

Turns out that inspiration (in the form of a concise algorithm to handle case-mismatches on all types of filesystems) struck while I was in the shower. https://github.com/kovidgoyal/calibr...da2c37a0842b66

Just think what Calibre would be like if he took more showers each day. But, he would become the cleanest and most wrinkled programmer in the world.

I have been known to linger in my showers till the hot water runs out. I do most of my serious thinking in there

Think what you could accomplish with a bigger water heater!

You do great work!

Maybe this is why the code is so clean.

All kidding aside, I really do appreciate your program along with all of the various plugins.
