The AcquireParams type exposes the following properties.
Properties
![]() ![]() | ![]() ![]() | ![]() ![]() | ![]() ![]() |
Member | Description | |
---|---|---|
![]() | Aborting |
Set to false to cancel the acquisition of images (e.g. during the OnProgress event)
|
![]() | AcquireFrameBottom | AcquireFrameBottom is the bottom of the rectangle to acquire measured in inches Note: Not supported for DCIM retrieval. |
![]() | AcquireFrameEnabled | If AcquireFrameEnabled is True, it enables the properties AcquireFrameLeft, AcquireFrameRight, AcquireFrameTop and AcquireFrameBottom. Note: This is only required for API Types of Twain. For other types AcquireFrameEnabled is always true. |
![]() | AcquireFrameLeft | AcquireFrameLeft is the left of the rectangle to acquire measured in inches. Note: Not supported for DCIM retrieval |
![]() | AcquireFrameRight | AcquireFrameRight is the right side of the rectangle to acquire measured in inches. Note: Not supported for DCIM retrieval. |
![]() | AcquireFrameTop | AcquireFrameTop is the top of the rectangle to acquire measured in inches. Note: Not supported for DCIM retrieval. With WIA ensure you set AcquireFrameLeft/AcquireFrameTop before AcquireFrameRight/AcquireFrameBottom. |
![]() | AutoFeed | If AutoFeed is true, the scanner will automatically feed the next page from the document feeder. Note: Not supported for DCIM retrieval |
![]() | BitDepth | Specifies the bit depth (bits per channel) of the image to scan. Note: Not supported for DCIM retrieval |
![]() | Brightness | Brightness value. Note: Not supported for DCIM retrieval |
![]() | Contrast | Contrast value. Note: Not supported for DCIM retrieval |
![]() | DuplexEnabled | If DuplexEnabled is True, the scanner scans both sides of a paper; otherwise, the scanner will scan only one side. Use this property only within IEImageList component to enable/disable duplex mode. Note: Not supported for DCIM retrieval Default: False (Scan only one side) |
![]() | DuplexSupported | If DuplexSupported is True, the scanner can scans both sides of a paper; otherwise the scanner will scan only one side. Note: Not supported for DCIM retrieval |
![]() | FeederEnabled | FeederEnabled enables the feed loader mechanism when present. Use this property only within IEImageList component to disable the feed loader. Note: Not supported for DCIM retrieval |
![]() | FeederLoaded | Use the FeederLoaded property to determine whether there are documents loaded in the Source's feeder. Note: Not supported for DCIM retrieval |
![]() | Orientation | Orientation defines the orientation of the output image. Not all scanners support this capability. Note: Not supported for DCIM retrieval |
![]() | PaperDetectable | If PaperDetectable is True, the scanner is able to detect paper. Note: Not supported for DCIM retrieval |
![]() | PhysicalHeight | PhysicalHeight is the maximum physical height (Y-axis) the scanner can acquire (measured in inches). Note: Not supported for DCIM retrieval |
![]() | PhysicalWidth | PhysicalWidth is the maximum physical width (X-axis) the scanner can acquire (measured in inches). Note: Not supported for DCIM retrieval |
![]() | PixelType | PixelType is the type of pixel data that a scanner is capable of acquiring. Notes: - Not supported for DCIM retrieval - Passing ieapOther as the PixelType will acquire using the default/current properties You can determine what formats the device supports by using IsPixelTypeSupported |
![]() | Rotation | Specifies how much the Source can/should rotate the scanned image data prior to transfer. Note: Not supported for DCIM retrieval |
![]() | SelectedSource |
Allows to get and set the current acquiring device. String format is the same used by AcquireParams.Sources[] string list.
|
![]() | Sources | Contains names of all acquisition sources. Items are formatted as follows: Device Name||Index of Location||API||Device Type E.g. My Cool Scanner||3||TWN||SCN |
![]() | Threshold | Threshold specifies the dividing line between black and white. Allowed values: 0 - 255. Note: Not supported for DCIM retrieval |
![]() | VisibleDialog | If True, the camera/scanner user interface is displayed when Acquire is called. Default: True Note: Dialogs are never shown for DCIM retrieval |
![]() | XResolution | XResolution is the DPI (Dots per Inch) in the X-axis. Note: Not supported for DCIM retrieval |
![]() | YResolution | YResolution is the DPI (Dots per Inch) in the Y-axis. Note: Not supported for DCIM retrieval |
