[hpoj-devel] ptal-hp scan image height enhancements

[<pa...@rc...>]

Hi,

I just added the capability for "ptal-hp scan" to auto-detect the image
length/height even in situations where the device doesn't report it.
This means the end of "corrupt JPEG data" errors and oversized images.
The "-length" switch is still supported if you really want to override
the image height, and it now also supports decreasing or increasing the
height if you put a plus or minus in front of the number.  I updated
SCAN-HOWTO to reflect these changes.
