Viewing/editing xpgt files

ShellShock · 07-21-2014, 01:41 PM

OK, I know that xpgt (Adobe page templates) are an abomination and not part of the epub standard, but in the real world we have to deal with this spawn of the devil, by replacing it with sensible css. However, the Calibre editor will not even display the xpgt read only, which makes composing the css equivalent cumbersome (-> export xpgt, open in external editor etc).

Any thoughts on putting xpgt viewing support into the editor? Or even better, support for editing the xpgt--just a plain xml editor would do (I promise to wear my tin foil helmet at all times!).

Thanks

In 9 times out of 10, all the XPGT is doing is altering the ePub's margin. So you can do it in the CSS without needing to see the XPGT file. I have yet to see one that specifies multiple columns.

In my experience, the xpgt usually sets the margin-top at the beginning of a chapter, and it is this that I really want to see so I can replicate it in css.

SS
Use the Unpack utility ('U'), then you can use anything to edit (view) that file

As an interim measure, that works great!

You're welcome.

I just look into this. The file will not open in my version Calibre64, Vista64. Maybe this is an effect related to the other problem "V 1.46 - Error with Author Link"?

Best regards,
Armin

+1 Now it is working. Thanks for this modification.

ShellShock · 07-26-2014, 06:42 AM

It is not working for me: "calibre, version 1.46.0
ERROR: Unsupported file format: Editing files of type application/adobe-page-template+xml is not supported".

In content.opf I had this:

Code:

<item href="Misc/page-template.xpgt" id="pt" media-type="application/adobe-page-template+xml"/>

Whereas in the html files I had this (same epub):

Code:

<link href="../Misc/page-template.xpgt" rel="stylesheet" type="application/vnd.adobe-page-template+xml" />

Which matches the code change for this enhancement. So I changed content.opf to

Code:

<item href="Misc/page-template.xpgt" id="pt" media-type="application/vnd.adobe-page-template+xml"/>

which means I can now edit the xpgt.

My brief research suggest both forms (with and without the vnd prefix) are used, suggesting this requires a further code change to cater for the vnd prefix.

Already done, for next release.

theducks · 07-26-2014, 02:18 PM

today I saw a: cover-template.xpgt file
(first time ever) along with the page-template.xpgt

Go Adobe, You managed to break Kovids new feature in a single day

In Adobe's world, only their software is used for reading epubs. Sheer hubris.

Divingduck · 07-28-2014, 01:26 AM

I found at weekend 3 books not working. One of them had a file name template.xpgt.

Kovid, if you need some not working examples, let me know.
