SANE EPSON Backend - News
Navigation
- 2003年02月15日: (Version 0.2.34)
Fixed problem with "usb " configuration.
- 2001年11月11日: (Version 0.2.15)
All strings are now tagged with the Sane I18N macro.
Experimental support for the scanner button. There is a new control in the frontend
"Wait for Button". When this switch is enabled, then the scanner will wait (after the
scan process is started with the frontend scan button) until the scanner button is pressed.
This frontend's "Cancel" functionality will not work when this "wait for button" functionality
is in waiting mode. It will work again once the button is pressed, and the scanner starts to
send data.
Fixed the check for scanners that need the color channel swapping. Should now also work for the
Asian version of the Perfection 1640.
I've again made available a RPM for SuSE 7.2 with the latest Sane release. Also added a link
to EPSON Kowa's backend for EPSON scanners to the main Sane page on this site.
- 2001年05月25日: (Version 0.2.07)
Allow more than 8 bit color depth even for preview mode
since Xsane can handle this. Some code cleanup.
Removed ancient code that was used to determine the resolution
back when the backend still had a slider for the resolution
selection.
- 2001年05月22日: (Version 0.2.06
Added sense_handler to support the GT-8000 scanner. Thanks to Matthias Trute
for figuring out the details.
Also added experimental code to use USB scanner probing. You need a kernel patch
for this. The patch is available from the download page.
- 2001年05月19日: (Version 0.2.05)
fixed the year in the recent change log entries - I now that it's
2001...
Finally fixed the TPU problem with B4 level scanners
- 2001年05月13日: (Version 0.2.04)
Removed check for '\n' before end of line
Free memory malloced in sane_get_devices() in sane_exit() again
- 2001年04月22日: (Version 0.2.03) Check first if the scanner does support the set film type
and set focus position before the GUI elements are displayed.
This caused problems with older (B4 level) scanners when a TPU
was connected.
- 2001年03月31日: Looks like I finally got a good handle on the number of lines
that I have to strip in the 'color shuffle' mode for the Perfection 610/640
scanners. It seems to be working correct now. Get the latest backend
from the download page
- 2001年03月03日: I installed SuSE 7.1 last weekend and was pleased for the first
time with their Sane support. They've distributed the latest Sane
version 1.0.4 and they also have the USB support for all EPSON USB
scanners. There is however just one small problem: Because of the code
freeze for 1.0.4 I was not able to get my latest changes in. So here is
a tar file for SuSE 7.1 that provides the latest backend that I released
Xmas last year: libsane-epson.so.1.0.4.gz
Just uncompress and copy this file over the existing /usr/lib/sane/libsane-epson.so.1.0.4 library
and enjoy the new features.
- 2000年12月28日: The IEEE-1394 interface on the high-end EPSON scanners
is now supported: Check out my IEEE-1394
page
- 2000年12月25日: The bit depth selection is back in the CVS repository. There
were some problems with the Perfection610 in bi-level mode, these are
fixed now. Did some cleanup and added more comments to the code.
- 2000年12月09日: I just changed the version on the web site because of a
but that was discovered shortly after I released the last version. If
you were one of the "early-adopters" and your colors are all screwed
up (on a Perfection1240) then please download this new version. It is
possible that the Perfection1640 now has some problems, so I'm waiting
for some feedback.
- 2000年12月09日: Fixed a problem introduced with the>8bit enhancement.
Mike Porter fixed the user defined gamma tables for negative scanning.
These enhancements are not in the CVS repository and the snapshots
for SANE 1.0.4 because of the feature freeze. I will commit these
changes as soon as the freeze is lifted.
- 2000年12月02日: The biggest change is that now scanners with more than 8bit color
depth are fully supported. This means that e.g. the Expression1600 can be
used with the full 36bit color information. However: This is not supported
by e.g. the Gimp or xscanimage (and I'm pretty sure scanimage also does not
support this). I tested this with
xsane, which does support this. The Perfection1640 is not yet supported,
there seems to be an image quality problem with this scanner, but I'm working
on this.
I also made some changes to the Perfection610/640 code, which should however not
be visible to the user.
- 2000年11月23日: Added support for the Expression 1600. This scanner does allow to
set the focus manually either on the glass surface, or 2.5mm above the glass.
The output is still only 24bit, even though the scanner does support 36bit
externally. I am working on this.
- 2000年06月28日: Fixed the bug when running scanimage -T: The scanner now recovers from
this without any problems.
- 2000年06月13日: When scanning negatives the images are now inverted.
- 2000年05月31日: Added support for multiple EPSON scanners, now it's possible to scan
with two scanners at the same time - I tried it with my Perfection1200S and
the Perfection610. I don't know if it also works if you have to scanners on
the same bus (SCSI or USB). The scanner internal color correction is now
accessible through the SANE interface, it's just not easy to come up with
values that make sense... Some UI tweaks.
And finally fixed the problem with the Perfection610: You may experience a
few lines of "garbage" at the beginning and/or the end of the scan, but
everything in between is correct.
- 2000年03月27日: Removed request for push button status. this caused problems with
older scannes. Updated the desc file and fixed some typos.
- 2000年03月22日: Fixed a problem with the A4 function level scanners (GT-6500/ES-600c).
Plus some minor code cleanup and fixes.
- 2000年03月06日: I would like to thank the EPSON Developer Relations department. They were
very helpful and gave me access to command specifications. If you are in the market
for a scanner take a good look at the EPSON scanners: I think that companies providing
support for Linux projects should also be supported
- 2000年03月06日: I hope this finally gets rid of the occasional hang after the warmup
phase. Some times (or most times, depending on who you ask :-) the warmup
signal went away between the failed ESC G command and the following "get extended
status" command. In these cases the backend did not re-issue the last command.
- 2000年03月02日: The Perfection 610 is now supported. This scanner is only available
in a USB version.
