[sane-devel] SANE2 plans: RFC
Le Samedi 9 Ao=FBt 2003 12:34, Major A a =E9crit : Hi, I think that we should get the SANE2 implementation rolling, even if the standard isn't completely finalized. A standard is never final without even a single frontend and backend to use it. As Henning has said, adapting the test backend and scanimage should be first. But how shall we do that in CVS? The frontend should be easy enough because it can check for the backend version to see whether SANE1 or SANE2 is used, making it completely transparent to the user. But there is no version-check facility for frontends, so backends will be a bit more difficult.=20 Just a thought. Could SANE2 introduce a handcheck protocol to determine whi= ch=20 API is used : frontend_knows_versions( list_of_versions ) backend_agrees_to_use( version ) frontend_confirms_use_version( version ) If those functions are not found in backend - SANE1 If those functions are not called by frontend - SANE1 That would avoid a CVS mess up. As I did not follow the whole thread about that, I may be completely wrong,= =20 tell me if this is the case. Have a nice day, Thomas.

[sane-devel] Current TODO list
Hi, TODO (2003-07-25) todo [snip] backends * All backends: Check that global variables are initialized propperly. sane_init can be called more than once (if sane_exit was called before)! Global variables must be either initialized in sane_init or reset in sane_exit. At least these backends segfault: - microtek - hp5400 Some work has been done for hp5400. Just a few questions : * may the backend be called after a sane_exit() ? * is this needed for const global variables ? * could you explain me what the problem is with global initialization ? doc --- * desc files: - Change all description files to use the new status keyword: avision, canon, canon630u, coolscan2, fujitsu, hp, hp5400, hpsj5s, microtek, microtek2, plustek, sharp, st400, umax1220u. done for hp5400.
backend status: (was Re:[sane-devel] Current TODO list)
Hi, Thank you Henning for your explanation. I thought it could be due to a platform specific weird initialization. in the hp5400.desc file, when I set the backend status to beta, the make gives me the following warning : [sane-desc] Warning: DEPRECATED backend status `beta': setting status of backend `hp5400' to `good' So i set it to good and then it says to me : [sane-desc] ERROR: unknown status of backend `hp5400': `:good' Bye, Thomas.
[sane-devel] error in linux/videodev.h
Hi, snip Follows the errors : In file included from /usr/include/linux/videodev.h:14, from v4l.c:76: /usr/include/linux/videodev2.h:432: parse error before v4l2_std_id /usr/include/linux/videodev2.h:432: ISO C forbids data definition with no type or storage class Maybe that's the result over our pedantic warning settings. Try with --disable-warnings. Looks like the header file is not ISO C-conforming (for whatever version of ISO-C). I'll try that later and tell you what it changes. Where did you get videodev2.h from? Is it from your version of libc (which one)? Or is /usr/include/linux a link to /usr/src/linux/include/linux and you have installed a 2.5 kernel? Looking with the rpmdrake tool (Mdk 9.1 installed) it says that videodev2.h belongs to : glibc-devel-2.3.1-10mdk or kernel-source-2.4.21-0.13mdk I am wondering if this is exact or if it belongs to another package I would have tried on the machine (they have been numerous). We'll have to think about supporting v4l version 2 anyway. There is an old v4l2 backend, but nobody yet responded to the question if v4l2 is the same as the new version 2 kernel interface. Have a nice day, Thomas.

[sane-devel] CVS freeze ?
Hi everybody, Sorry for the silly question but I have been a bit SANE-offline for a while, and I didn't find quickly the answer in the mail archive. I wanted to commit into CVS some changes about the hp5400 backend. Is there a CVS freeze at the moment or may I do it ? And before that, is there a compile farm or some kind of, to verify at least it compiles ok on various platforms before commiting it ? Thomas. PS : changes are not functional, they are only to make a synchronization between hp5400backend sourceforge CVS project and SANE CVS project. PS2: I have been messing around a lot before finding the DEBUG_NOT_STATIC trick to avoid the missing symbol sane_debug_hp5400_call !!!

Hi Henning, We had about 6 beta testers report. Some of them had problems for=20 installation, but once installed, none reported big bugs. All of them installed on Linux.

[sane-devel] New release of the alpha version of hp5400 SANE backend
Hi everybody, Martijn have done more great work those days. It is still an alpha versio= n as=20 it is not full featured and there are still two major bugs :=20 * the image goes fuzzier as the resolution increases=20 * 1200 and 2400 dpi images are scrambled. Except of that, 75 and 150 dpi are working pretty well. The release is downloadable at http://sourceforge.net/projects/hp5400back= end/ The most significant modifications are : - improved calibration - implemented gamma correction - Add support for new SCANOFFSET command 0xE700. This means we can remove all the options relating to offsets in xsane itself. This might require adjustment depending on the model of scanner. - Add support for the two kinds of types of scan requests. This is what controls whether to use the scan offsets. - Add a ScanType parameter so we can distinguish between previews and nor= mal scans. In future we'll use this to control the scan speed. - Add code to protect the scanner against silly mistakes. It will restric= t your scan area to the glass and no more.=20 Have a nice day, Thomas.

Except of that, 75 and 150 dpi are working pretty well. What do you mean by fuzzier? Is this the problem of vertical shift between separate color components (R G B)? Yes. That point is under control as we know how to correct it during th= e=20 image composition, reading colors on separate lines. Problems with scrambled images could be caused by an overflow of the internal data buffer (at least that's what I found with niash12/14/19 chips). In that case, you should be able to correlate this to backtrack= ing (quickly moving back and forth of the lamp). Do the scrambled images also occur if you scan only a narrow vertical strip? At first I thought you would be right but even with a narrow vertival str= ip,=20 most pixels are absent. I'll send you on a separate mail a tiny part of= the=20 vertical strip. It shows colored vertical lines (red and green). It might be related to the query sent to the scanner. We have to check if= all=20 the flags are correct.

I would like to add the .desc file to CVS (external backends) so your backend is found in the scanner search engine. I've edited your file a Oops, error. It should be in CVS. bit. If you write one entry for each model, it's found easier (nobody seaches for 54xx). Do you have a 5400 and 5470? As far as I know, the 5490 is similar, therefore I've added it as untested. Is this correct? Status is development under way with untested alpha release. I forgot to mention that it has only been compiled for the moment under l= inux=20 and can probably break on other OS.

Situation is: 1. It finds the scanner and warms up the lamp 2. It performs two calibrations scans like in windows 3. Performs the preview scan and dumps it to disk This is only a test program, not a backend. Things still to do: 1. Actually use results of calibration scans.
