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:
The scanner drivers are updated.
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);
