Black Line at Right edge of Jpeg #2

Hi, some of the images that are produced have a black line of pixels at the right edge. It doesn't appear to be consistent some downloads have it others don't, and the size of it varies. When it is present it is the same on all the images. On one set of downloads it is one pixel, but I have seen it gone up to even.
Here is an example from KDCW_KS04000001020001_68 with one pixel
016_p-015

Here is an example from KDCW_MF03000001020001_68 with seven pixels
009_p-009

And here's one with no black pixels from KDCW_AM12000002020001_68
009_p-009

The black pixels aren't present on the original images in the comic-walker reader. Thanks for the application and any help.

Thank you for reporting issue with many examples! ❤️

Before decoding (rearranging) the image, it doesn't seem to have extra black areas.
Maybe it's a bug of calculating rearrangement or a misusage of ImageMagick.
I'll investigate more deeply.

I've found that:

  • The original image has black borders.
  • There's dummyWidth and dummyHeight parameters to hide the black borders.
    For instance, KDCW_MF03000001020001_68 has dummyWidth=7 and dummyHeight=0.

Now I'm searching for where those parameters come from.
