Hello friend. I see that my Vectors ideas come to your post ;)

I have use ImageProcess to read BitMaps and edit regions of pixels. This is example

Local $oSource = ObjCreate("WIA.Vector")
Local $oImg = ObjCreate("WIA.ImageFile")

$oImg.LoadFile(@DesktopDir & "\test.bmp")

ConsoleWrite("Reading file for pixels color..." & @CRLF)

Local $oARGBData = $oImg.ARGBData

For $i = 1 To $oARGBData.Count
    $oSource.Add(Dec(Hex($oARGBData($i), 6))) ; RGB 3byte
Next

ConsoleWrite("Successfully read " & $oARGBData.Count & " pixels" &  @CRLF)

@Ascer,

Thanks nice example... 

Indeed your VECTOR example triggered me to look further into the COM Object options.

@ MLipok

There was already a kind of UDF started more then 10 years ago

I don't have time to make this a complete UDF unfortunately... But anyone who does feel free.

One good thing to notice is that a COM libr. that ran on XP is still shipped and working on Windows 10.

Some more examples for the collection  :) 


Scan paper to file ( via ShowTransfer )

;~ wia_ScanFile()
Func wia_ScanFile($FileExt = "bmp", $iDevice = 1) ; Scan to file from scanner
    Local $hTimer = TimerInit()

    Local $oCommonDialog = ObjCreate("WIA.CommonDialog")
    Local $oDeviceManager = ObjCreate("WIA.DeviceManager")

    Local $oDevInfo = $oDeviceManager.DeviceInfos($iDevice)
    Local $oDevice = $oDevInfo.Connect

    Local $iIndex = 1 ; https://docs.microsoft.com/en-us/windows/desktop/wia/-wia-wia-property-constant-definitions
    $oDevice.Items($iIndex).Properties("6146").Value = 2 ;colors
    $oDevice.Items($iIndex).Properties("6147").Value = 300 ;dots per inch/horizontal
    $oDevice.Items($iIndex).Properties("6148").Value = 300 ;dots per inch/vertical
    $oDevice.Items($iIndex).Properties("6149").Value = 0 ;x point where to start scan
    $oDevice.Items($iIndex).Properties("6150").Value = 0 ;y point where to start scan
    $oDevice.Items($iIndex).Properties("6151").Value = 5100 ;horizontal exent DPI x inches wide
    $oDevice.Items($iIndex).Properties("6152").Value = 7002 ;vertical extent DPI x inches tall
    $oDevice.Items($iIndex).Properties("4104").Value = 8 ;bits per pixel
    $oDevice.Items($iIndex).Properties("3098").Value = 1700 ;page width
    $oDevice.Items($iIndex).Properties("3099").Value = 2196 ;page height

    Local $sFormatID
    Switch $FileExt
        Case "bmp"
            $sFormatID = "{B96B3CAB-0728-11D3-9D7B-0000F81EF32E}"
        Case "GIF"

        Case Else
            $sFormatID = "{00000000-0000-0000-0000-000000000000}"
    EndSwitch

    Local $sImg = "image_" & @YEAR & '-' & @MON  & '-' &  @MDAY & '_' & @HOUR  & '-' &  @MIN  & '-' & @SEC
    Local $oImg = $oCommonDialog.ShowTransfer($oDevice.Items($iIndex), $sFormatID, True)

    $oImg.SaveFile($sImg & "." & $FileExt)

    Return $sImg & "." & $FileExt
EndFunc   ;==>wia_ScanFile

 

List scanners

;~ wia_ListDeviceices()
Func wia_ListDeviceices() ; list of scanners
    Local $oDeviceManager = ObjCreate("WIA.DeviceManager")
    Local $n = $oDeviceManager.DeviceInfos.Count
    ConsoleWrite("Number of Deviceice found = " & $n & @CRLF)
    Local $a[$n + 1][2]
    $a[0][0] = $n
    For $i = 1 To $oDeviceManager.DeviceInfos.Count
        $a[$i][0] = $oDeviceManager.DeviceInfos($i).Properties("Name").Value
        $a[$i][1] = $oDeviceManager.DeviceInfos($i).DeviceID
        ConsoleWrite(" Device " & $i & ":" & @TAB & $a[$i][0] & @TAB & "(" & $a[$i][1] & ")" & @CRLF)
    Next
    Return $a
EndFunc   ;==>wia_ListDeviceices
