Nice analyses on the image quality. :) Our hpaio sane backend performs no up-stream image enhancements, so what you see is uncompressed RGB or jpeg directly from the scanner.
The windows scanning solution does performs up-stream image enhancements which may or may not be desirable. In order to provide a simple open source scanning solution that can be generalized for many HP devices, we prefer to leave image enhancements to other open source tools like Gimp. -dave > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of PB > Sent: Thursday, October 04, 2007 9:59 AM > To: hplip-devel@lists.sourceforge.net > Subject: [HPLIP-Devel] Strange quality using hpaio sane > backend with a C4180 > > > Hi. > > Since upgrading to HPLIP v1.7.7 I can finally use my HP C4180 > scanner/printer device for scanning, but the outcome is rather ugly. > > In order to give the developers the possibility, to "see" > what I'm talking about, I've prepared some image samples: > > http://www.das-werkstatt.com/c4180/ > > > These noisy-artifacts around the edges seem rather strange > and unnatural, so I thought I'd post this issue here. > Maybe someone could tell me if that's normal or not - or if > that could be fixed somehow (settings?). > > > Thanks, > PB > > > > > > > -------------------------------------------------------------- > ----------- > This SF.net email is sponsored by: Splunk Inc. > Still grepping through log files to find problems?
