Yeah, I tried that, Input Profile = default, Output Profile = Kindle DX, Comic Input preferences all unchecked except "Keep Aspect Ratio" (# of Colors set to 16)... results in the same squished output.

Looks like the output profile option it not being honored in the GUI. I'll look into and and post when it's fixed.

Have you tried using the CLI ebook-convert to see if that works?

Is there any way of getting calibre to automatically drop page numbers when converting from pdf files. What i mean is that if i convert a pdf file to lrf or epub, the page numbers from the pdf are still present and included as part of the text. My preferred method of converting from pdf at the moment is to first drop the pdf into mobireader and then convert from the resulting prc file using calibre. This fixes the problem by getting rid of the page numbers and the mobipocket reader seems to do a decent job of reformatting the pdf.

TevK,

With regards to CBZ, wouldn't the aspect ratio constrain the image based on the shortest pixel direction? That would cause the image to adjust in size accordingly. So no matter which way you use it, the image will be small. (Unless you can scroll an image on the Kindle - or other ebooks).

Sorry, your comment just struck me as odd. I haven't tried any manga in ereader software, let alone hardware. So I might not understand what you're encountering. I'm just thinking about what I see happen in image software (photoshop, etc).

The keep aspect ratio option constrains the image so that it is always the starting aspect ratio. Meaning if the image is 16 inches wide and 9 inches tall it will have an aspect ratio of 16:9. The option makes sure the image is always 16:9. So if the width is changed to fit inside of the document than the height will be changed accordingly. It just keeps the ratio it does not prevent the image from being scaled up or down.

Calibre does not currently support this. Your best options are to either use another conversion program such as you are or to crop the PDF and remove the header/footer from each page.

@JSWolf
@TevK

The command line works(ish). The keep aspect ratio option was not being sent to the conversion pipeline though the GUI and there were a few bugs in the dx profile. Those have been corrected and it should be working in the next release.

Anyone else seeing that Calibre freezes up after adding a few PDFs? I get about two in and then on the third it just stays on the adding window perpetually until I abort.

Is it a specific PDF or just when you add a few at a time? Also, what is the size of the files?

Hmmm, I guess I assumed that something like a Fit to Screen was automatically used. Along with Keep Aspect Ration it would mean 16:9 (per your example) but scaled downward based on the smallest screen dimension. Which might have accounted for what TevK was seeing.

I did... The login page just redirects me to the register page. I think I've registered about 3 times. Hence, why I asked if the site stores session using IP. Because thanks to my "brilliant" ISP, my IP changes every few seconds.

EDIT: Nevermind... Finally, found a proxy that works.

I was just playing with the custom recipe for wikipedia from this post:
https://www.mobileread.com/forums/showthread.php?t=41457

I wanted to look into trying to include images, so I yanked the beautiful soup function to see how the default HTML looked with images as an epub.

The first thing I noticed was that some of the text sizing changed pretty drastically - nearly everything was the same size. Digging into it, it looks like Calibre normalizes the div classes until nearly everything is using the same class, calibre4. I didn't test this in .5, but since the css handling has seen some pretty major changes I assume that it's quite different there.

An example (from the 'Tree' example article in the plugin):

Original HTML:

Code:

<div class="thumbcaption">
<div class="magnify"><a title="Enlarge" class="internal" href="/wiki/File:Leavessnipedale.jpg"><img width="15" height="11" alt="" src="/skins-1.5/common/images/magnify-clip.png"/></a></div>
<a title="Beech" href="/wiki/Beech">Beech</a> leaves.</div>

Calibre Generatet HTML:

Code:

<div class="calibre4">
<div class="calibre4"><a href="/wiki/File:Leavessnipedale.jpg" title="Enlarge"><img src="images/img2.png.jpg" width="15" height="11" alt="" class="thumbimage"/></a></div>
<a href="/wiki/Beech" title="Beech">Beech</a> leaves.</div>
</div>

calibre4 had been used previously as the class id for general content, as you can see above several new classes were introduced, but instead of incrementing to calibre5 and calibre6, calibre4 was re-used.

I've attached the plugin with the beautiful soup function removed, as this particular example is in the image caption.

Any PDFs and any sized file. I basically spent the afternoon adding PDFs 2-3 at a time (one at a time until it stopped working), restarting calibre, doing it again, etc. Files ran from less than a meg to 50megs.

Is anyone else getting crashes when converting a couple hunded or so LIT files at a time? It doesn't seem to be related to a specific book; it just crashes after 100 or so. I doesn't appear to be a memory issue since everything else seems to be fine when it happens.

Update: In fact, it appears to be crashing precisely after converting the 100th LIT to MOBI conversion in a batch, if the batch is larger than that.

TevK · 06-15-2009, 01:14 AM

I tried using ebook-convert via command line, using this command:

ebook-convert /Users/tev/Desktop/fairy_tail_sample.cbz /Users/tev/Desktop/fairy_tail_sample.mobi --title="Fairy Tail Sample" --authors="Mashima, Hiro" --keep-aspect-ratio --right2left --input-profile=default --output-profile=kindle_dx

It worked...sorta. Now instead of the image being stretched to fit the width and squished to half the height, it's correctly proportional, but only half the height.

I'm guessing this is one of the bugs in the DX profile that was mentioned, which will be fixed in the next release. I'm eagerly awaiting it. =)
