[sane-devel] Problems in 1.0.18, sane_fujitsu, USB fi5120C.

[Lonny Granstrom]

Hello,

HISTORY:
Have been using SANE scanimage & scanadf running through BASH scripts since Feb2005.
All command arguments are added & assembled using database stored strings.
Example for fi4220C2:
	Model Default = "--mode Lineart --resolution 150 --y-resolution 150"
        Duplex ADF = "--source ADF --duplex both"
        Color Scan = "--mode Color"
BASH scripts take all these strings and produce:
"--mode Color --resolution 150 --y-resolution 150 --source ADF --duplex both"

PROBLEM:
Latest release for sane-fujitsu in July2006 (1.0.18) has broken BASH scripts.

COMMAND HELP ISSUES (1.0.18):
1. Running scanadf/scanimage --help -d <USB-fi5120C> documents arguments that
   are NOT accepted: --pagewidth, --pageheight.
2. Help messages for -x, -y, --pagewidth, & --pageheight do NOT provide proper
   information, descriptions are all the same.
   (e.g., for ADF, both -l and -x MUST be used to properly mimic the missing
          --pagewidth argument)
3. Changes to --source options are misleading.
   (e.g,; --source ADF Front [as documented default] does NOT work,
          fact that value MUST be quoted is not indicated.
          Command that works: --source 'ADF Front' or --source "ADF Front")
4. All these issues have been addressed and corrected in database.

FUNCTIONAL ISSUES:
[NOTE: none of the following occurs if --source ommitted (using default)]
A. Running the command from same BASH script now fails 100% with the following:
     scanadf: setting of option --source failed (Invalid argument)
   Code from bash script:
     #!/bin/bash
     ...
     # Execute SCAN command
     if [ "${SCAN_USING_FLATBED}" -eq 1 ]; then
       if [ "${DEBUG}" == "Yes" ]; then
         (
          echo "Scanning Command:"
          echo "${SCAN_SCRIPT_FULL} ${SCAN_OPT_FULL} >${OUTPUT_FILE} 2>${SCAN_LOG}"
         ) 1>>${DEBUG_LOG}
       fi
       (
        ${SCAN_SCRIPT_FULL} ${SCAN_OPT_FULL} >${OUTPUT_FILE} 2>${SCAN_LOG}
       )
       SCAN_RTN="${?}"
     else
       if [ "${DEBUG}" == "Yes" ]; then
         (
          echo "Scanning Command:"
          echo "${SCAN_SCRIPT_FULL} ${SCAN_OPT_FULL} ${OUTPUT_FILE} 2>${SCAN_LOG}"
         ) 1>>${DEBUG_LOG}
       fi
       ## --command not executing properly using 1.0.18 below-- ##
       ${SCAN_SCRIPT_FULL} ${SCAN_OPT_FULL} ${OUTPUT_FILE} 2>${SCAN_LOG}
       SCAN_RTN="${?}"
     fi

B. Cut & Paste of expanded syntax from debug log works from the command Line.
   Expanded syntax from debug log (line space separates script variables):
     /usr/local/bin/scanadf                                   \

            --device-name net:ws198:fujitsu                   \
            --mode Color --resolution 150 --y-resolution 150  \
            --source 'ADF Duplex' -l 62.4 -x 100.0 -y 60.0    \
            --scan-script /usr/local/bin/scanpnm2tif.sh       \
            --start-count 1                                   \

            --output-file /tmp/scan/scannedimg%03d.pnm        \

            2>/tmp/scan/status.scn
   Two TIFF files, scannedimg001.tif & scannedimg002.tif are created showing front
   and back of document scanned.

C. Replacing single-quotes with double-quotes does not change A. & B. results.
      --source "ADF Duplex"

D. Placing double-quotes in BASH Script syntax: 
     ${SCAN_SCRIPT_FULL} "${SCAN_OPT_FULL}" ${OUTPUT_FILE} 2>${SCAN_LOG}
   produces the error:
     scanadf: unrecognized option, `${SCAN_OPT_FULL}`

E. If ran from the command line - same error occurs.
   Expanded syntax from debug log (line space separates script variables):
     /usr/local/bin/scanadf                                   \

            "--device-name net:ws198:fujitsu                  \
            --mode Color --resolution 150 --y-resolution 150  \
            --source 'ADF Duplex' -l 62.4 -x 100.0 -y 60.0    \
            --scan-script /usr/local/bin/scanpnm2tif.sh       \
            --start-count 1"                                  \

            --output-file /tmp/scan/scannedimg%03d.pnm        \

            2>/tmp/scan/status.scn

Any help or suggestions would be appreciated?
