problem with CBR/CBZ conversion for Kobo

gweeks · 04-02-2011, 10:58 AM

I'm getting some truncation with the CBR/CBZ conversion on a Kobo. The Calibre version is 0.7.53 and the KOBO wireless firmware version is 1.7.4 r21156.

It looks like one or two pixels off of the left edge of the converted 540x718 test image and about seven pixels off of the bottom. The pixels are in the image, the Kobo just doesn't display them.

I can provide the test CBZ and epub as well as a picture of the screen if it's needed.

The CBR/CBZ conversion works great for the Nook. Of course the Nook converted epubs bleed off on all four edges when put on a Kobo.

Is there any way to correct this short of a new Calibre build?

In the comic input settings specify a different size to which the images should be resized. Experiment until you find the perfect size. Once you do, let me know and I will fix the default size in the Kobo profile

Thanks.

I'll give it a try and let you know what I come up with.

I ended up with 536x710. I'm not absolutely sure I'm not still sometimes seeing a pixel dropped on the left edge or not.

OK, I'll adjust the profile values.
