WIA scanner, can't get/set 4104 and 6146 properties (color, color depth)

Question

I'm trying to configure the color and depth in a Kodak i2600 scanner using WIA on a C# project. Several posts refer to parameters 6146 (which can take the values ​​1 (color), 2 (gray scale) or 4 (white and black)) and 4104 (color depth = 24).

WIA Automation for scanner color intent is not working

Windows image acquisition - setting device properties in C#

Detect all available scanner resolutions using WIA

These properties do not appear when I iterate the array scanner properties.

I use a foreach loop to iterate properties and this is the list that I get:

I was with same problem (kodak i2400).

If you want, try this:

WIA.Item item = device.Items[1] as WIA.Item;

AdjustScannerSettings(item, 150, 0, 0, 1250, 1700, 0, 0, 1);


private static void AdjustScannerSettings(IItem scannnerItem, int scanResolutionDPI, int scanStartLeftPixel, int scanStartTopPixel,
        int scanWidthPixels, int scanHeightPixels, int brightnessPercents, int contrastPercents, int colorMode)
{
    const string WIA_SCAN_COLOR_MODE = "6146";
    const string WIA_HORIZONTAL_SCAN_RESOLUTION_DPI = "6147";
    const string WIA_VERTICAL_SCAN_RESOLUTION_DPI = "6148";
    const string WIA_HORIZONTAL_SCAN_START_PIXEL = "6149";
    const string WIA_VERTICAL_SCAN_START_PIXEL = "6150";
    const string WIA_HORIZONTAL_SCAN_SIZE_PIXELS = "6151";
    const string WIA_VERTICAL_SCAN_SIZE_PIXELS = "6152";
    const string WIA_SCAN_BRIGHTNESS_PERCENTS = "6154";
    const string WIA_SCAN_CONTRAST_PERCENTS = "6155";

    SetWIAProperty(scannnerItem.Properties, WIA_HORIZONTAL_SCAN_RESOLUTION_DPI, scanResolutionDPI);
    SetWIAProperty(scannnerItem.Properties, WIA_VERTICAL_SCAN_RESOLUTION_DPI, scanResolutionDPI);
    SetWIAProperty(scannnerItem.Properties, WIA_HORIZONTAL_SCAN_START_PIXEL, scanStartLeftPixel);
    SetWIAProperty(scannnerItem.Properties, WIA_VERTICAL_SCAN_START_PIXEL, scanStartTopPixel);
    SetWIAProperty(scannnerItem.Properties, WIA_HORIZONTAL_SCAN_SIZE_PIXELS, scanWidthPixels);
    SetWIAProperty(scannnerItem.Properties, WIA_VERTICAL_SCAN_SIZE_PIXELS, scanHeightPixels);
    SetWIAProperty(scannnerItem.Properties, WIA_SCAN_BRIGHTNESS_PERCENTS, brightnessPercents);
    SetWIAProperty(scannnerItem.Properties, WIA_SCAN_CONTRAST_PERCENTS, contrastPercents);
    SetWIAProperty(scannnerItem.Properties, WIA_SCAN_COLOR_MODE, colorMode);
}

private static void SetWIAProperty(IProperties properties, object propName, object propValue)
{
    Property prop = properties.get_Item(ref propName);
    prop.set_Value(ref propValue);
}
