Equations...

Have published a few books with equations but quality is generally poor. After researching the problem IMHO documents created in LaTeX are far superior to anything else. Is there any reason why a LaTeX to Kindle/eBook importer cannot be provided as well as epub and HTML? With the financial resources available to Amazon this should not be an insuperable problem. Most people who write technical books will be able to acquire the basics of LaTeX in a few days, many will even know it now. From Amazon's point having more and better quality eBooks will generate higher revenue, so in business terms may be a sound investment.

Rather than ask people who have no connection to KDP wouldn't it make more sense to ask the KDP boffins directly? Use the Contact Us button at the bottom of the page. Since you've researched the topic extensively, perhaps you could tell them how to make it work in the context of a reflowable e-book. Good luck.

You're assuming that it's simply because there's no magic LaTEX importer. That's not the issue. The source file--whether it's perceptually inferior or superior--is utterly irrelevant.

The issue is, there is no precise or perfect control, in eBooks, over vertical and horizontal positioning of characters and elements in an eBook. Period. The reason that you think that LaTEX is so superior is because like every other print medium, you can create correct equations. But just imagine what that would be like, if you couldn't control the positions of a number or numbers, in ratios or calculations. Wouldn't be so freaking great, would it?

Well, that's the same problem faced by ePUB and MOBI. No precise control, so the creation of a simple ratio, for example, is impossible. That's why there's no exporter, and why your ePUB didn't come out so great. That's why experienced eBook makers use images for MOBI for any mathematical or scientific equations.

You're right Hitch.
Only need to convert formula in image.
Two ways:
-using a graphic editor and export image
-using Word or Libre Office and make a screenshot

I totally get the idea that you would insert an image of the equation - I'd almost figured that one out for myself, but the screen shot idea is a really easy way of doing that! But something that has always puzzled me is that when you have a set of images to include in the text of an e-book, and you've extracted the images, put them in a separate folder and so on, how does the system know where to put them back in? Also, I'm assuming here that if you treat the equations as images, they have to be stored in a separate folder in the same way as regular images?

I ever published six books. Each book contains near 80 images. Most of these images were designed with a software call CorelDraw. You can use free software like GIMP or Inkscape.
You can create all equation in the same Gimp or Inkscape file but you will need to Export each equation independently of one another.

Good luck,

Hey, is CorelDraw still around? We used to have a copy 2 or more computers ago! Probably still have it somewhere, but unfortunately it's probably not compatible with Windows 8.

Many thanks for that though, it's helpful. I think I have enough of an idea now on this subject.

Hi,

Don't know why the forum didn't alert me to these replies. sorry about that.

You tell it where they go. You have to manually create each image, and then insert it where it goes, by hand. Whether you're using Word, or whatever, that's how it works. When you then export the file to HTML, a second folder is created, with the images, and the locations for each are annotated, in code, in the HTML file. The renderer replaces the images in the final ebook file.

Having said all that, be aware that you need to pay close attention to the HTML, because those inline images, should you use any, need hand-coding around them, IN the HTML, to perform correctly in both KF8 and KF7 mobis.

HTH.

Of course it is. I still use WordPerfect to write all my books. It makes great PDF's for CreateSpace.
Go ahead and laugh!
