[sane-devel] Completing epson backend deprecation

I have only tested 4990 and I think there is no confirmed test for the GT-X900 - has any one a v700 and v750 please test it, but remember to use the git version of sane, I don't think it is in any released version. I don't have the possibility of verifying from the git now, but I think this refers back to my issues with the TPU2 on v700. The solution got committed according to http://lists.alioth.debian.org/pipermail/sane-devel/2011-December/029234.ht ml and I can verify that using my own build (from which the diff is produced) works on v700. you properly right, I think this error can be closed.

[sane-devel] coolscan3 - nikon LS-2000 - multi sampling
HI I have got an old Nikon LS-2000 scanner, and it should work with coolscan3, but I can't see how to make multi sampling with this driver, and I don't think it can !! Where do I get some technical information about the scanner, so we/I can incorporate this feature in the driver. Claus -- next part -- An HTML attachment was scrubbed...

[sane-devel] epson2 driver and epson perfection 4990
There is a problem with the resolution setup for Epson perfection 4990 (and
4870 I think). Because of buggy firmware it do not give the resolutions over
3200, but it too have 4800, 6400,9600,12800. It is important to have especial
4800 (and 9600) because the are not interpolated.
Here is a patch with a solution in epson2-ops.c about line 230
if (dev-dpi_range.max dev-res_list[dev-res_list_size - 1]) {
/*
* Setup the right dpi for
* Image Scanner Perfection 4870/4990 (GT-X700/GT-X800)
* EPSON Programming guide for
* EPSON Color Image Scanner Perfection 4870/4990
*/
if (e2_dev_model(dev, GT-X800)
|| e2_dev_model(dev, GT-X700)) {
DBG(1, integrating resolution list
(4800,6400,9600,12800)\n);
e2_add_resolution(dev, 4800);
e2_add_resolution(dev, 6400);
e2_add_resolution(dev, 9600);
e2_add_resolution(dev, 12800);
}
else {
int val = dev-res_list[dev-res_list_size - 1] * 2;
DBG(1, integrating resolution list (%d-%d)\n,
val, dev-dpi_range.max);
while (val = dev-dpi_range.max) {
e2_add_resolution(dev, val);
val *= 2;
}
}
}

What is missing from the epson2 backend to reach the complete status for the Epson V700 Photo? maybe some particular features of the scanner are missing. I myself don't own one, but given that is has been listed as good on epson backend it should work well on epson2 too. I've not yet made up my mind. Maybe I just take the risk and buy the device. I took the risk with the epson 4990 and ended up with the job to hack the backend, mostly because the firmware in the scanner made som funny things and have some funny features too. I hacked the epson driver, but this driver did not do the extended commands, but before I got the epson backed update to the extended commands the epson2 driver from Alessandro came up, and it did the job for me, except for the funny buggy software of the epson 4990 scanner, which I have hacked today (it is in the driver now). Sow if your scanner not have funny firmware it proberly runs on epson2 (if it use the ESC/I, but I think that both v700 and v750 use the ESC/I commands, but don't blame me if I'm not right) commands, but . We can too ask epson for the programmers manual, I did that with the 4990 and got them without problems. I don't know how much you can do, can you compile a packet your self ? - do you programe/understand some c ? Best Claus Boje
[sane-devel] Epson Perfection 4990 driver
I have made the part of epson2 backend that special for the Perfection 4990 scanner. Every thing should work, but more testing would be nice. I have too made the part of the epson backend (the old driver) for 4990, but there are a few thing not working, especial with the transperant unit. Claus Boje Mandag den 11.

I don't think I have introduced incompatibilities but I can't be sure. If I remenber right, then the epson2 driver has not been out with a release yet, when it comes out you proberly will get some reports, I will keep an eye on the list. The only reason I found your driver was because I need some of the commands not in the epson driver and I started to write them my self but before I realy got started I found that you have done the job (thank you). The only error I found was a memory leak with (real) big images, the rest was some epson 4990 problems, and I think there will maybe be some with the others epson scanners, but I don't hope - I only have a 4990 to do test on, sorry for that.

[sane-devel] xsane Segmentation fault
Hi Working on a patch for the epson perfection 4990 scanner for the epson2.c driver (not in any stabel version of sane yet) I found after heavy debugging that xsane makes a Segmentation fault when i get data bigger than 32K from sane_read. When the sane_read is called the max_length == 65536. I am getting the error after return from sane_read. In a shellbox I got this message *** glibc detected *** malloc(): memory corruption (fast): 0x08423648 *** Segmentation fault Best Claus Boje
