Description

Error with gb.scanner with Brother DCPL2550DW scanner

1)I get the scanner name without any problem:

      Dim xScanName As String[]
      Dim xscanner As String

       xScanName = New String[]
       For Each xscanner In Scanners
       xScanName.Add(xscanner)
       Next
       Print xScanName[0]

The result is :  brother4:net1;dev0

2) When I run $ scanimage --device-name='brother4:net1;dev0' -A

The result is:

scanimage: rounded value of br-x from 215.9 to 215.88
scanimage: rounded value of br-y from 355.6 to 355.567

All options specific to device `brother4:net1;dev0':
  Mode:
    --mode Black & White|Gray[Error Diffusion]|True Gray|24bit Color|24bit Color[Fast] [24bit Color[Fast]]
        Select the scan mode
    --resolution 100|150|200|300|400|600|1200|2400|4800|9600dpi [200]
        Sets the resolution of the scanned image.
    --source FlatBed|Automatic Document Feeder(left aligned)|Automatic Document Feeder(left aligned,Duplex)|Automatic Document Feeder(centrally aligned)|Automatic Document Feeder(centrally aligned,Duplex) [Automatic Document Feeder(left aligned)]
        Selects the scan source (such as a document-feeder).
    --brightness -50..50% (in steps of 1) [inactive]
        Controls the brightness of the acquired image.
    --contrast -50..50% (in steps of 1) [inactive]
        Controls the contrast of the acquired image.
  Geometry:
    -l 0..215.9mm (in steps of 0.0999908) [0]
        Top-left x position of scan area.
    -t 0..355.6mm (in steps of 0.0999908) [0]
        Top-left y position of scan area.
    -x 0..215.9mm (in steps of 0.0999908) [215.88]
        Width of scan-area.
    -y 0..355.6mm (in steps of 0.0999908) [355.567]
        Height of scan-area.

3) When I do scanning 
       $himage = Scanners["brother4:net1;dev0"].Scan()
       DrawingArea1.Refresh

I get error: [6] Type mismatch: wanted float got string instead
             Scanners.GetOptions.164
