[GUI Plugin] Generate Cover - Page 40

MCBastos · 07-19-2016, 10:14 PM

OK, I just noticed an odd bug with the way Generate Cover processes the data fields:
If there's an "&" character, it treats it as if it were " & " -- that is, it inserts spaces before and after the "&" character.
Which results in ugly extra spaces whenever it runs into an "&" -- like, say, for a book with two authors.
Partial workaround: manually edit the text in the "content" tab so "&" is not surrounded by spaces -- that reduces the double space to single spaces. AFAIK, however, there is no way to have the "&" surrounded by no spaces at all.

EDIT: Further experimenting revealed a few more details -- on initial load of the plugin, it performs as expected (no extra spaces). But if you change any of a variety of parameters (font size, which fields should appear on the cover etc.) then the extra spaces suddenly appear.

I coincidentally had a cover with '&' this morning and paid attention. It should be noted that my '&' was in the title and no extra spaces appeared. I modified my author to have '&' and the extra spaces did indeed appear when I removed my custom text as a test.

Is the stroke option back?

Hi,

I was wondering if this plugin has the ability to generate covers from powerpoint files?

I'm building a library of technical presentations and many of them are in ppt or pptx.

What I do currently is convert to pdf and extract from there but it is quite cumbersome.

I'd like to automatically generate it from the calibre dropdown.

Thanks!

The short answer is no - i.e. the plugin can't generate covers from a Powerpoint file, in fact the plugin can't generate covers from anything. 'Generate Covers' is a bit of a misnomer - its more like a 'Cover Creator'.

This may be easier than creating a PDF ==>> [PDF] Export PowerPoint slides as JPEG - Clark University

Just drop the resultant JPG into the Book Details (right) sidebar.

From what I was able to notice/test:

- Font strokes are not back yet (if they ever will)
- The "&" parsing bug seems to have been fixed -- I wasn't able to reproduce it anymore
- The "blank lines" bug still remains
- The "can't remove image if it's set to be stretched as background" remains (but this is really unimportant, since it doesn't actually affect the ability to create covers)

Thanks for the suggestion, it's every bit as cumbersome though... I guess I need to ask the main dev then.

Thank you!

Is there anywhere I can download an old version (that is, one compatible with Calibre 2.56) of Generate Cover?
I'm using the current versions in my day-to-day process, but I thought that, disk space being ridiculously cheap the way it is, I could keep an old version of Calibre Portable with the old version of the plugin for the odd occasion I really want fonts with outlines.

eschwartz · 09-04-2016, 03:04 AM

No, usually plugin developers only post the latest version of the plugin.

Some plugin developers use a version control system to track the changes in their plugin, from which you can derive old versions... but this plugin doesn't appear to be on e.g. GitHub...

Perhaps someone has an old copy saved somewhere.

You can copy the plugin file from a OLD Backup of of the Calibre config folder:plugins;

Use Preference:Plugins: Add from file button (at bottom) to install it

An awful lot of people don't even backup their libraries, even fewer backup their configuration folder, and I doubt many of those would do version backups. I know I don't, I keep the old ones for 60 days, after which they're automatically purged.

I'd start with updating Calibre. Current is 2.67--you're 21 versions behind.

Ooops! That would help, wouldn't it!
Thanks for pointing it out!

Hey, just wanted to say how much I greatly appreciate your continued development of this plug-in. I take my covers (probably a bit too) seriously and I looooove it's existence.

Not sure if you're interested in any feature requests and not sure if this is possible, but if so -- I'd find it very useful to add the ability to select multiple images at once in order to do a mass delete. Or, alternatively, for the highlight/selected item to stay in about the same place when an image is deleted (rather than move to the topmost image).

I often find myself needing to batch delete as my tagging system evolves and this would be helpful in that.

Regardless, thanks so much for creating and maintaining this excellent tool.
