[GUI Plugin] Generate Cover

[sp000n]

Appreciate the replies, BetterRed & Tanjamuse.

Adobe Reader Pro, which I have, lets me extract page(s) but not as JPEG. I worked out a solution automating the Calibre steps with AutoHotkey. I'll post it in the right spot.

Hi, just had one of those instances where I added a new cover and the next time I went to use the plugin, there was a message about configuration file corruption. I'd previously thought this was tied to using hyphens in the names (and stopped using them, which seemed to stop the corruption from occurring until fairly recently), but this case involved no hyphens, so, as to what happened:

1) Had two epubs selected. Clicked on Generate Cover plugin.
2) Plug-in was on a cover "Bucky Steve 7" I'd created some time ago and had used earlier today to add a cover to a new book in an ongoing series. Cover was set as 500x700 dimensions using a non-stretched image also named "Bucky Steve 7", contents order of title, image, author, series, all text centred
3) On the settings page, clicked "Add Setting" and from that profile created a new one named "Botanical Diaries"
4) Clicked "Add Image To This List" and imported an image also named "Botanical Diaries"
5) On the "Dimensions" tab changed to a stretched image
6) On the "Contents" tab changed order of elements to title, author, image, series
7) On the "Fonts" tab changed the fill colour
8) Changed title and author to right-aligned
9) On the "Dimension" tab I decreased the bottom, left and right margins. NOTE - previously reported error with changes to left margin incorrectly affecting starting placement of right-aligned text is still is effect
10) On the "Fonts" tab adjusted sizes of font
11) Saved and applied the cover
12) Decided to further tweak the cover, clicked on "Generate Cover", corruption error message appeared - details reported that "Bucky Steve 7" had incorrect internal name of "Botanical Diaries" and was being fixed
13) New cover "Botanical Diaries" is still present and looks correct. Previous cover of "Bucky Steve 7" is gone from list entirely and will need to be recreated.

Every time I go to use this plugin, an error pops up that says "TypeError:QPixmap(): argument 1 has unexpected type 'ImageView'. Can anyone help please? I've already upgraded to 2.23.

I saw that message once running Count Pages PI after doing todays update W7 x64
Kovid is the something iffy here?

This? Problem, as per other thread, is a function change in Qt5.4.1, which was fixed for calibre itself but not if a plugin also called the same type of code.

Edit2: I believe calibre now bundles Qt5.4.1 so plugin errors should show up in all official builds as well.

Can you link to that thread? I'm not finding it. Thanks.

I quoted my post from that thread.
Well, that thread linked to a calibre bug report.

Ah, I didn't realize you could cross-quote like that. Thanks.

Looking at what was changed in calibre, it looks like a very simple fix:

# Change dialogs.py:152 from
        self._pixmap = QPixmap(self)
# to
        self._pixmap = QPixmap()

Attached is a test version with that change. It works for me--but then it wasn't broken before for me.

UPDATE: Attachment now has updated version number and change log and is in the officially preferred uncompressed state.

Great, I've dropped Kovid a PM asking him to update the first post.

[eschwartz]

FWIW.

Kovid is in a different timezone, plus might have other preoccupations.
I would drop a line to DoctorOhh, theducks, or BetterRed instead.

Might get a resolution, oh, a few hours earlier.

Is this version ALSO compatible with older Calibre's?

Just tried it with the portable versions of v1.48 and v2.14 and both worked. Good question, though.

If you update the change log (inside the Zip) and version, I can move it ti the first post. PM when ready please

[BetterRed]

Don't forget to update the version number - has happened before
