25 stars or one?

[chaot]

Hallo!

In a book there are 25 stars, seems me senseless. I would like to summarize to one star.
They are seemingly identical, since the byte data differ minimally.


star01.jpeg_798_B · · · · · · star03.jpeg_799_B · · · · · · star24.jpeg_800_B

I know the job (in technical sense).

But my question is whether the request is inadvisable for any reason?

[eschwartz]

It should be safe.

I've seen this before, when a book was clearly OCRed.
The same image was picked up multiple times by the OCR software, but with ever-so-slight differences in the image data (a pixel here or there) so the software created multiple images.

rename the other (non-star) images
Then your S&R will be simpler

Pick the best and give it a non-'star' name,
REGEX search for star\d+ and replace with the above

OR
Replace that mess with a Text star and assign it in a class that allows you to set a size and margin

.mystar {display:block;font-size: 1.2em;text-align center; margin: 1em 0; text-indent: 0;}

OCRed (OCR)→Initialism of Optical Character Recognition (the principle) or Optical Character Reader (the scanning device)
Realistic!

I don't refuse to do what you say, just for interest: Why? That does not seem necessary.
Your explanation (about S&R) is not clear to me.


3 non-star images

3 non-star images

Why:
1) Reduce file size (the book) for either way

2)Remove jitter (the image appears to jump around) between, what should be the SAME image., when viewed rapidly in succession.


My idea for S&R is simply a work flow methodology I use to K.I.S.S.
Usually (not always) these are the bulk of the images, the rename means a less exacting search

@theducks Sorry, I understand less and less.

I renamed these 3 non-star images (_typo, cov, head), but the size remains exactly the same, as I expected.

2) Remove jitter (the image appears to jump around) between, what should be the SAME image., when viewed rapidly in succession.

What's K.I.S.S?

Usually (not always) these are the bulk of the images, the rename means a less exacting search

To see what we got, I show it (the whole I can't, it's a .csv file, what calibre recognizes as an Invalid file).

Changing these just makes the S&R less likely to change the wrong SRC in the image use

You MISSED the step after that. Now replace all the uses (in the book) of Starxxx with the name if the new or single selected file. Once that is done, you can delete those NOW unused ,extra media files. That is how to shrink book size

the appearance of Jitter (wobble), is when the scaned images have different whitespace and alignments

I still see many 'Star' images. The whole purpose of my post was I thought that you wanted only ONE left. If the are unused (0 uses), that image can be deleted

[Thom*]

You are right, it makes no sense to have 25 stars when 1 would do. Probably this happened because the book was scaned and then converted to ebook using a program that didn't know any better. I would search for all reference to a "star" and replace a with one single "star". For example, using regex, search all text:

search: star[0-9][0-9]\.jpeg
replace: star01.jpeg

With this you will have changed all reference to star01.jpeg. Now you can deleted star02.jpeg through star25.jpeg as they are not used.

Why? Because the world will be a better place.
Remember - Keep It Simple Stupid!

I refuse to do that, it would be misleading.


Where you live

My mother tongue is German. And if I am not wrong, the question should be in correct English: Where do you live? (With question mark.)

So far! The rest will be commented later.

Now give me please some time to do it. Possibly there are more than one way, more or less sophisticated, with S&R and/or regexes or without.

Documentation follows.

[chaot]

Important Back-up the book before starting experiments.
(Save to disk→Save to disk in a single directory (which is to get established). E.g. my one is called Library#backed-up_experiments)

Rename one image, e.g. star01.jpeg to rats.jpeg

Files browser Images (rats.jpeg)


Files Browser Text (S with star\d+ & R with rats)(S with star[0-9][0-9]\.jpeg also functions)


Differences wetween books


Files Browser Images (Delete the 24 selected file(s)

Rename rats.jpeg to star.jpeg

Result

Files Browser Images (star.jpeg)
(Check Book is okay)

Job done!

You gave us further reasons for to do so, still I am not convinced (or I don't understand you).

OR
Replace that mess with a Text star and assign it in a class that allows you to set a size and margin

.rats {display:block;font-size: 1.2em;text-align center; margin: 1em 0; text-indent: 0;}

Please, where is to introduce that. I would like to test.

Of course, even though I had understood the methodology of approach, the regexes I had not known. These simplify the procedure considerably.

Your English is fine. Technical discussions can get lost when different languages and backgrounds are involved.

It is an additional optimization.

With the fixes you just did, you now have one (1) star image.

But you could remove that as well, and replace it with a text star:

*

which is less Kilobytes (actually bytes, 798 B --> 1 B)

I've always been more than happy with the following CSS+HTML instead of using images for change of scene:

# CSS
.scenebreak {
  text-align: center;
  text-indent: 0%;
  margin: 1em;
}

# HTML
<p class="scenebreak">* * *</p>

We got similar background.

Introduce the css-code (at the end (position nevermind))

F B stylesheet.css

S&R HTML-code

F B Text


Differences between books


Check Book The file content_images_star.jpeg is not referenced [content_images_star.jpeg]

Delete star.jpeg→Check Book OK.

Just I see: @eschwartz has schmuggled me some 3 stars inside for change of scene (changeable in stylesheet.css)

Short and painless, all very much!
