Table 3-5 Supported capabilities (continued)
ICAP_CONTRAST Application can use this capability to inquire, set, or restrict the values for contrast
used in the driver.
ICAP_ROTATION Determines how the driver can/should rotate the scanned image data prior to
transfer. It is always measured in degrees. Currently, it can only be used with
multiples of 90.
ICAP_XSCALING Determines how the driver should scale the X-axis of the scanned image data. A
value of 1.0 is equivalent to 100% scaling (unscaled). Values less than or equal to
zero cannot be used. It will match with the value set for ICAP_YSCALING.
ICAP_YSCALING Determines how the driver should scale the Y-axis of the scanned image data. A
value of 1.0 is equivalent to 100% scaling (unscaled). Values less than or equal to
zero cannot be used. It will match with the value set for ICAP_XSCALING.
ICAP_THRESHOLD Specifies the dividing line between black and white. This is the value the driver will
use to threshold, if needed, when the application requests a BW image.
CAP_DUPLEXENABLED Specifies if the scanner scans both sides of a paper or scans only one side of the
image.
CAP_DUPLEX Indicates whether the scanner supports duplex. If so, it further indicates whether
one-path or two-path duplex is supported.
ICAP_PIXELFLAVOR Specifies the size of the pixel whose numeric value is zero (minimum data value).
CAP_INDICATORS Indicates if the driver will display a progress indicator during acquisition and
transfer, regardless of whether the source’s user interface is active.
ICAP_HALFTONES Specifies a list of names of the halftone patterns available within the Source.
ICAP_BITDEPTHREDUCTION Specifies the reduction method the source should use to reduce the bit depth of the
data.
ICAP_MINIMUMHEIGHT Allows the source to define the minimum height (Y-axis) that the Source can acquire.
ICAP_MINIMUMWIDTH Allows the source to define the minimum width (X-axis) that the Source can acquire.
ICAP_PHYSICALWIDTH Specifies the maximum physical width (X-axis) the Source can acquire (measured in
units of ICAP_UNITS).
ICAP_PHYSICALHEIGHT Specifies the maximum physical height (Y-axis) the Source can acquire (measured in
units of ICAP_UNITS).
CAP_AUTOSCAN Enables the Source’s automatic document scanning process.
CAP_AUTOFEED Indicates if the Source will automatically feed the next page from the document
feeder after the number of frames negotiated for capture from each page is
acquired.
ICAP_ORIENTATION Defines which edge of the paper is the top: Portrait or Landscape
ICAP_BITDEPTH Specifies the pixel bit depths for the current value of ICAP_PIXELTYPE.
ICAP_COMPRESSION Allows the application and source to identify which compression schemes they have
in common for Buffered Memory and File transfers.
ICAP_BITORDER Specifies how the bytes in an image are filled by the source.
ICAP_PLANARCHUNKY Allows the application and source to identify which color data formats are available.
There are two options, “planar” and “chunky.”
CAP_UICONTROLLABLE Indicates if the source supports acquisition with the UI disabled.
CAP_PAPERDETECTABLE Determines whether the device has a paper sensor that can detect documents on the
ADF or Flatbed.
