Why are my grayscale images JPEG wrapped in a TIFF header?

SmartSource default grayscale format is TIFF wrapped JPEG. Other formats are supported, including JPEG, shown below.

As of release 4.4.1.0-2.0.34.0, RangerForSmartPVA has an option to strip the TIFF header from the JPEG grayscale images.

1) Set up the appropriate generic options:

In the generic options file at "C:\ProgramData\Silver Bullet Technology\Ranger\Scanner Plug-ins\Burroughs-SmartPVA\GenericOptions.ini" see the following options:

    [OptionalDevices]
    NeedImaging=true
    NeedFrontImage2 =true
    NeedRearImage2=true


2) Set up the necessary driver options:

In the driver options file at "C:\ProgramData\Silver Bullet Technology\Ranger\Scanner Plug-ins\Burroughs-SmartPVA\Burroughs-SmartPVA.ini" see the following options:

    [Image.FrontGrayscale]
        //
        //Compression type
        //    3 = JPEG
        //    20 = Grayscale Bitmap
        //    21 = Grayscale PNG
        //The default is 3.
    COMPRESSIONTYPE=3

    [Image.RearGrayscale]
        //
        //Compression type
        //    3 = JPEG
        //    5 = Full Resolution JPEG
        //    20 = Grayscale Bitmap
        //    21 = Grayscale PNG
        //The default is 3.
    COMPRESSIONTYPE=3

    [Image.GENERAL]
    //JpegTiffWrapped
    //Determines whether grayscale jpeg images are tiff wrapped
    // false - not tiff wrapped
    // true - tiff wrapped (default)
    JpegTiffWrapped=false


3) See the below code example to set these options programatically:

    SetGenericOption("OptionalDevices", "NeedImaging", "true");
    SetGenericOption("OptionalDevices", "NeedFrontImage2", "true");
    SetGenericOption("OptionalDevices", "NeedRearImage2", "true");
    SetDriverOption("Image.FrontGrayscale", "COMPRESSIONTYPE", "3");
    SetDriverOption("Image.RearGrayscale", "COMPRESSIONTYPE", "3");
    SetDriverOption("Image.GENERAL", "JpegTiffWrapped", "false");
