Use alt value of img tags when possible while Epub:EXTERNAL_REF_IGNORE is used

[Grandt]

At the point where this happens in EPub, I'm already parsing the HTML
DOM, so I'll make the change there.

Thanks for a good idea though :).

I'll be updating GitHub shortly. The addChapter function have a
parameter for external references. Previously
EPub::EXTERNAL_REF_REPLACE_IMAGES would cause addChapter to replace all
images with "[image]", I've changed that if it's present, it'll
use the alt tag value instead of "image", else it'll fall back to just
"image"

Which version do you use? The regular EPub.php or the new EPub250.php?

Cheers

Hello!

I think, it could be good to display the alt value of images instead
of simply removing entire tag.

It can be done with this regexp for example:

$html_content = preg_replace('/<\s_?img.alt="(.?)"._?>/', '${1}', $html_content);

I'll use this regular expression in my epub plugin for the Leed RSS
reader and I think, it can be usefull for you too.

Thanks for your great work on PHPePub !

I'm using Epub250.php simply because I've tried it first and it worked well for my needs (and because I like the modularity).

Indeed, I've used EPub::EXTERNAL_REF_IGNORE because I thought that it was not only about images, but really all external references (like video, audio, ..., but I don't know what a epub can contain).

I think, I'll use the REPLACE_IMAGES so. Thanks !

You are right, EXTERNAL_REF_IGNORE removes all externals. And it will
erase images entirely.
I'll have to think about that one for a short while. Should ignore place
the image alt value or not...

I'm currently playing with how to best support nested chapters (chapter
levels). The EPub.NCX alreasy suppirts it, but I'm still trying to
figure out how to expose this in the EPub.

Cheers.

Hi i'm currently using the Epub.php and i've noticed that when downloading external animated gif images. The images that has been downloaded loses its animation.

leikxile, even with the latest version updated 2 days ago. I added Gif's as a valid format (older readers using the Adobe Digital Editions, can crash on Gifs.)
You need to set $book->isGifImagesEnabled = TRUE;
If not, can I get you to send me an example book having this gif to [email protected] ?
