WIA_IPS_DESKEW_Y

The WIA_IPS_DESKEW_Y property, together with the WIA_IPS_DESKEW_X property, describes the upper two corners of a skewed image. The WIA minidriver creates and maintains this property.

Property Type: VT_I4

Valid Values: WIA_PROP_RANGE

Access Rights: Read/write

Remarks

The WIA_IPS_DESKEW_X and WIA_IPS_DESKEW_Y properties describe where the two upper corners of a skewed image are located within the bounding rectangle that the WIA_IPS_XPOS, WIA_IPS_YPOS, WIA_IPS_XEXTENT, and WIA_IPS_YEXTENT properties define.

The valid values for WIA_IPS_DESKEW_Y must be between 0 and (WIA_IPS_YEXTENT - 1). A value of 0 means that no deskew should be performed.

WIA_IPS_DESKEW_Y contains the number of pixels in the y-direction from WIA_IPS_YPOS to the y-coordinate of the leftmost corner of the image to be deskewed.
