[sane-devel] Possible bug in canon backend or > scanimage

Dear colleagues,
Thank you for your replies. I find that addition of the --all-options
is a nice idea to improve the user interface. Unfortunately it
does not solve my problem. This weekend I tried to debug sane
to find the source of the error. Just to remind you the problem:
scanner canoscan 2700F is supposed to have extra options (reported
when using --all-options flag, works with xsane) but this options
are not accessible with a scanimage (reported error
scanimage: unrecognized option '--af=yes')
As was pointed earlier, the message is coming from the getopt_long
function (frontend/scanimage.c:2094). With my compilation, the glibc
implementation of the getopt_long is used, therefore I could not
debug it. However, I have modified the scanimage.c in a way, to
printout all command-line parameters and the content of
full_optstring and all_options -- parameters of getopt_long
function (frontend/scanimage.c:2094). The output you can see in the
attachment (scanimage.out.highlight and scanimage.out.af). What I do
not like in the output is some (null) option-names in the printed
all_options (see line 29 of scanimage.out.af). This (null) string
is following after the "ae" option, which is still working.
All options below that (null) line do not work.
Here, just in case, few lines which I added to scanimage.c just before
while loop at the line 2094 to print parameters:
fprintf(stderr,"Full_options: %s\n",full_optstring);
for(i=0;i<all_options_len;i++)
fprintf(stderr,"ap: %s\n",all_options[i].name);
Please let me know your opinion on this "investigation".
I just noticed that there is active development of the genesys
backend. I have a canoscan 8400F scanner which is build with
the GL843 chip. I would like to help to make backend for this
scanner. Please let me know how can I help you.
I also have a canoscan 3200F scanner, which I would like to
rebuild to a "film" scanner. But before taking it completely
apart I can try to see if we can make it ruining with sane.
Please find attached the output of the sane-find-scanner
utility.
Best regards,
Myroslav
