I have found something interesting but have no idea HOW to implement it?? It seems the setting for the scanner are in the registry and must be changed that way or by specifically calling these constants on the device. WIA_IPS_YRES (ScannerPictureYres) Contains the current vertical resolution, in pixels per inch, for the device. An application sets this property to set the vertical resolution. The minidriver creates and maintains this property. Type: VT_I4, Access: Read/Write or Read Only, Valid Values: WIA_PROP_RANGE or WIA_PROP_LIST WIA_IPS_XRES (ScannerPictureXres) Contains the current horizontal resolution, in pixels per inch, for the device. An application sets this property to set the horizontal resolution. The minidriver creates and maintains this property. Type: VT_I4, Access: Read/Write or Read Only, Valid Values: WIA_PROP_RANGE or WIA_PROP_LIST WIA_IPS_OPTICAL_XRES (ScannerPictureOpticalXres) Note This property is supported only by Windows Vista and later. Horizontal Optical Resolution. Highest supported horizontal optical resolution in DPI. This property is a single value. This is not a list of all resolutions that can be generated by the device. Rather, this is the resolution of the device's optics. The minidriver creates and maintains this property. This property is required for all items. Type: VT_I4, Access: Read Only, Valid values: WIA_PROP_NONE WIA_IPS_OPTICAL_YRES (ScannerPictureOpticalYres) Note This property is supported only by Windows Vista and later. Vertical Optical Resolution. Highest supported vertical optical resolution in DPI. This property is a single value. This is not a list of all resolutions that are generated by the device. Rather, this is the resolution of the device's optics. The minidriver creates and maintains this property. This property is required for all items.Type: VT_I4, Access: Read Only, Valid values: WIA_PROP_NONE WIA_IPS_BRIGHTNESS (ScannerPictureBrightness) The image brightness values available within the scanner.Contains the current hardware brightness setting for the device. An application sets this property to the hardware's brightness value. The minidriver creates and maintains this property. Type: VT_I4, Access: Read/Write, Valid Values: WIA_PROP_RANGE WIA_IPS_CONTRAST (ScannerPictureContrast) Contains the current hardware contrast setting for a device. An application sets this property to the hardware's contrast value. The minidriver creates and maintains this property. Type: VT_I4, Access: Read/Write, Valid Values: WIA_PROP_RANGE WIA_IPS_ORIENTATION (ScannerPictureOrientation) Specifies the current orientation of the documents to be scanned. The minidriver creates and maintains this property. Type: VT_I4, Access: Read/Write, Valid Values: WIA_PROP_LIST ------------------------ Image Intent Constants ------------------------ Image intent constants specify what type of data the image is meant to represent. The WIA_IPS_CUR_INTENT scanner property uses these flags. To provide an intent, combine an intended image type flag with an intended size/quality flag by using the OR operator. WIA_INTENT_NONE should not be combined with any other flags. Note that an image cannot be both grayscale and color. WIA_INTENT_IMAGE_TYPE_COLOR (ImageTypeColor) WIA_INTENT_IMAGE_TYPE_GRAYSCALE (ImageTypeGrayscale) WIA_INTENT_IMAGE_TYPE_TEXT (ImageTypeText) WIA_INTENT_MINIMIZE_SIZE (MinimizeSize) WIA_INTENT_MAXIMIZE_QUALITY (MaximizeQuality) WIA_INTENT_BEST_PREVIEW (BestPreview) -- http://mail.python.org/mailman/listinfo/python-list
