Adding Alternative text for images.

rachealwaceke · 08-19-2021, 02:43 AM

I have an epub file i am working on,it does not have any error(it is valid)
But when i want to open it using sigil and edit the alt text using the access-aide plugin it fails to open.Any clue on how to solve this.

Looks like the attributes width and height have invalid values (see last two lines)

Apparently, PIL couldn't detect the width and height of the cover image. What kind of image file are you using as a cover image?

(If the file type is not listed on this page, the plugin won't be able to get its dimensions.)

You are the second person to post about this today? Or did you already post an issue on my Access-Aide github site?

The bug is exactly what Doitsu and Binchen have explained. One of your image files either is corrupt or is not supported by the PIL python module.

If you want me to look at it please post a private link to it (if not public domain) and PM me (KevinH) on this site with a link.

Update: Actually the image was NOT corrupt. It was just so wide and thin in height that when scaling it to create a thumbnail for the gui actually caused the scaled height to be truncated to 0 pixels.

This bug has now been fixed in Access-Aide_v053.zip which is now available for download in our Plugins Index or via https://github.com/kevinhendricks/Access-Aide
