Labeling (organizing) of images

[chaot]

The Adventures of Tom Sawyer (an Project Gutenberg EBook).

It has about 280 pictures and I want organize them without that typical Gutenberg filth.

_public_vhost_g_gutenberg_html_files_74_74-h_images_35-274.jpg

The book has 35 chapters, each with some pictures.

Calibre don't accept (via Bulk rename selected files)(with prefix image_chapter01_)
the starting number 001 (neither 01).
Strangely, it takes over the images of the second chapter (prefix image_chapter02_) with starting numbers 06, 07 etc.

Edit: Striked out, existing scheme (calibre pad it with the minimum necessary padding) was known, but simply overlooked by me.


image_chapter01_5 ... image_chapter02_06

It should look like

image_chapter01_001.jpeg
image_chapter01_002.jpeg
...
image_chapter35_273.jpeg
image_chapter35_274.jpeg

HowToDo?

[eschwartz]

No can do (as of today).

calibre automatically pads the number according to the renamed files.

If the renamed files start at 6 and go to 10, then they all get padded to two digits.
If they are all 1-digit numbers (1 to 5) they won't get padded.


I would name them chapter02-image-1 etc.

[theducks]

The file name is for humans
I just number them in order appearance, just in case

[phossler]

While it might be desired to include the chapter number and a 'from 1' sequence number, like theducks says, it's just for people. Is there a reason to use that specific naming convention?

I never tried bulk renumbering images, but it does work: the image files are renamed and links are updated.

[chaot]

Small intermediate question (detailed answer later): Where I can change the prefix to chapter? In this case, otherwise it would be possibly image etc.

Anyway, the possibility to change the prefix (as default) seems to me in some respects appropriate.


Bulk rename items Prefix: Chapter-

[eschwartz]

If you mean, whee can you set the prefix so that it will be remembered, there is no setting to do so.

I think the most common form would be Chapter-01, but anytime you are changing it, it will be very situation-specific. How often is the default the wrong form?

To put it bluntly: I do not criticize the default prefix Chapter- but their immutability. And the numbering that can't start (as default) with 01 or 001 or whatever. So I had to help myself with Chapter-01_Image-1 to Chapter-01_Image-5 and Chapter-02_Image-1 ... etc.
Even roman numbers I, II, III, IV for old books (like my example from Mark Twain). I admit, may be this idea doesn't make really mind!?

... but anytime you are changing it, it will be very situation-specific. How often is the default the wrong form?

Situation-specific or not, for a non-English one everything in English is wrong.
And what about Bulk rename ... of pictures? We write Image-01 etc.

Answer to your question: Very often!

Although Calibre's been a damn fine software, there's still something to do!?

Sometimes a thread starts (with a more or less definite opinion) and turns out in the course due to the meaning of others that own attitude was somehow wrong and needed to be revised.

Doing a good job always means a solid understanding of the matter and usable tools.
This maxim applies also for dealing with calibre.

There is also a difference whether there are a few dozen books to edit or some thousands - in the latter case one is willing more to invest (sweat).

And then we come to things like concepts. As a typical German (in this case) I do rarely something without a plan or concept. Commenting on what I mean here would be beyond the scope of this thread (will be dealt with in chaot's edit concepts (continuous thread).

@theducks wrote The filename is for humans ... and @phossler similar ... it's just for people.

That gave me reason for thinking. Before my claim was to put the File Browser entries in English, with lowercase letters for a professional look. BINGO, I admit that was wrong.

Since my edits made so far concern only a few books the upcoming changes is not too much hassle. The entries in the File Browser of my German, English and Spanish books are now will be set language-specific and start with capital letters.

I am not sure to got you right! But if, overview!

[eschwartz]

Well, for the sake of foreign-language users alone I'd say being able to change the default is a good thing. Excellent point.



As for padding the number, I guess you could always use the prefix:

image_chapter01_0

calibre will automatically pad it with the minimum necessary padding, based on the files it is renaming.
If you want extra padding (because you aren't renaming all of them at once) just add the extra padding to the prefix.

Maybe if Kovid does change the default prefix, he could make it a tiny bit smarter and have separate default prefixes for bulk rename of \text files (e.g. 'chap') and \images files (e.g. 'img')

[eschwartz]

Well, it appears the prefix is already localized, so it will appear in whichever language the interface is set to.
Which seems more logical to me anyway. There is such a thing as too many settings.


In the morning I will submit a patch that customizes the default prefix according to file type.

So now default prefixes depend on the type of file, which should help.
e.g. renaming a bunch of images will default to "Image-" instead of "Chapter-"
It still won't remember the last custom prefix you used though.

Hopefully this is enough to mitigate the problem.

And as I said, they are all translated -- actually, the new ones will need to have translations added on Transifex first -- so foreign-language users shouldn't feel left out.
(If you want to use the English GUI I guess it makes sense for calibre to offer the English prefixes...)

You are confusing about something already has been found to work well: Capitals at the beginning.
But your scheme is better than mine (the most important word Image should be at the beginning)(don't forget hyphens)(Images or anything else, please do not call zero), so Image_Chapter-xy_xy
or may be more clear Image-xy_Chapter-xy

calibre will automatically pad it with the minimum necessary padding, based on the files it is renaming.

That's known!

If you want extra padding (because you aren't renaming all of them at once) just add the extra padding to the prefix.

... renaming all of them at once ... is here not possible, and ... just add the extra padding ... cost so much labor and time. That's the point.

No change of default prefix Chapter-01, but add some default prefixes for bulk rename in form of a pick list (the tiny bit smart way) & own choice default prefix.

I know Transiflex already and sure to be able to help.

@eschwartz Posts #10 & #11 were not considered currently by me. Let's wait for the new scheme and the practical use (as it feels like).

Be thanked for your nice attention of my plea.

[eschwartz]

Well, happy to provide what help I can.

In about a day you can test out the changes, see how they integrate in your workflow.
