Inkpad 3: images and illustrations are too small

crs · 11-29-2020, 06:44 AM

The default ePub 2 reader of Pocketbook Inkpad 3 (PB740) shows images quite small. This is a problem especially with books that contain graphs and mathematical expressions.

With firmware v.5.20.1010 this was the case for all ePub files.

With firmware v.6.1.1069 this has fortunately improved. The release notes for this firmware version mention that they "Fixed some problems displaying illustrations in certain books in EPUB, DOC, DOCXformat", which might have something to do with this.

Looking at the extensions.cfg and handlers.cfg files in system/config/, it seems that there are now (in firmware v6) several built-in reader apps:

eink-reader.app
eink-reader_with_blink.app (PB Reader EPUB 3?)
eink-reader_with_epub2.app (PB Reader EPUB 2?)

I wonder if "blink" is referring to https://en.wikipedia.org/wiki/Blink_(browser_engine).

Either way, it seems that opening ePub files (even ePub 2 files) with "PB Reader (EPUB 3)" will show all images much larger than "PB Reader (EPUB 2)" did.

"PB Reader (EPUB 2)" still shows images much smaller, in the same way as the default reader in firmware v5 did for all ePub files.

I'm posting this just as a heads-up: if you like your ePub illustrations large, try installing the latest firmware from https://www.pocketbook-int.com/int/s...tbook-inkpad-3 and opening your ePubs with the "PB Reader (EPUB 3)" reader via the library (press and hold on an ePub file).

It's a combination of the images and the coding. That's why they look too small.

Attached are 4 images of the same page from the same epub file with different devices:

- Adove Digital Editions 4.5
- iPad's Kobo Books reading app
- Inkpad 3, with the "PB Reader (EPUB 3)" app
- Inkpad 3, with the "PB Reader (EPUB 2)" app

"PB Reader (EPUB 2)" is the only one that shows the image too small. All the other ones show the image large enough that the image is readable.

With KoReader you can show images on Pocketbook in full screen.

But don't you also need the code set to show the images full screen?

A long press on an image in the book enlarges the image to screen width. You can then rotate it by 90 degrees so it is enlarged to screen height.
