Kobo stock reader vs KOReader rendering

[jospalau]

Here it it is another screenshot.

When word spacing is large in KOReader, the spacing between words in both is almost identical.

It is just a grab of the screen in each program and then a conversion with convert to blend the images.

You should compare ePub to KoReader for the word spacing. KePub has rather large word spacing by default.

It is an ePub. The spacing it is similar and you can see in some words that kerning it is better in KOReader.


Clara 2E, Amasis font and the ePub doesn't specify line-height

Are you sure it's ePub and not KePub?

Yes. It is a recent book converted with Calibre to epub. I send the books to my devices with Rsync.

I set margins and everything to be as close as possible. KOReader word spacing needs to be large so they are almost identical.

Why does KOREader word spacing need to be large?

You can tweak everything in KOReader. With word spacing as large (you see this is the bottom pane) is how both programs render the text nearly the same way. If you set for instance word spacing medium which I think is by default, spaces between words are smaller and KOReader can fit more words per page.

What it is interesting is seeing how the kerning is better in KOReader. For instance, gra_duation, but it is just a simple test.

Kerning should not be any better in either program. Kerning either works or it doesn't.

But KOReader has several kerning options you can apply and with HarfBuzz and according to the image I posted, it renders better (for this only example with this specific font...), so not all the programs render the same.

It's been posted that KOReader does not yet work on the Clara BW. So if you buy a Calara BW, you'll have to go ePub and/or KePub.

You can see another example with your favourite font. It took me more time to select the font and set the font size in the stock reader than to do all the rest...

Kerning still worse, you see the first two sentences Hav e and m y wi fe. See the word leaving in the third line.


And also KOReader fits more words per line. That's why after the first paragraphs the text is not the same in both screenshots.

What makes no sense is the word emotionally. In the red text, the kerning looks good. In the black text, the kerning look not so good as ly is not as close as the red text.

I'm using the same font and I've just had a look at the word really in the book I am reading. The ly looks the same as it does in red in your sample. I know for sure I am reading ePub and not KePub.

Are you sue you are not using KePub?

100% sure. I never used KePub and I don't transfer the books from Calibre directly. I sync them manually via Rsync.

Can you please try one of the ePub from the MR library and see how words with ly look with CareInk6SP? Thanks.
