Page Size and Orientation Code Examples

Last Updated: 1/24/2017

These code examples show the following WIA_IPS_PAGE_SIZE scenarios:

  1. The minidriver reports the settings.

  2. An application sets the WIA_IPS_PAGE_SIZE property to WIA_PAGE_LETTER.

  3. An application sets the WIA_IPS_ORIENTATION property to LANSCAPE.

  4. An application changes the WIA_IPS_XEXTENT property to a smaller value.

Example 1: The minidriver reports the settings

In the following code example, the minidriver sets a custom selection area before an application sets any WIA properties. In this case, the selection area represents the entire flatbed.

WIA_IPS_PAGE_SIZE = WIA_PAGE_CUSTOM
WIA_IPS_PAGE_WIDTH = 11500
WIA_IPS_PAGE_HEIGHT = 14000
WIA_IPS_ORIENTATION = PORTRAIT
WIA_IPS_XPOS = 0
WIA_IPS_YPOS = 0
WIA_IPS_XEXTENT = 1150
WIA_IPS_YEXTENT = 1400
WIA_IPS_XRES = 100
WIA_IPS_YRES = 100

Example 2: An application sets the WIA_IPS_PAGE_SIZE property to WIA_PAGE_LETTER

In the following code example, the minidriver changes the page size from custom values to a standard letter size of 8500 × 11000 pixels.

WIA_IPS_PAGE_SIZE = WIA_PAGE_LETTER
WIA_IPS_PAGE_WIDTH = 8500
WIA_IPS_PAGE_HEIGHT = 11000
WIA_IPS_ORIENTATION  = PORTRAIT
WIA_IPS_XPOS = 0
WIA_IPS_YPOS = 0
WIA_IPS_XEXTENT = 850
WIA_IPS_YEXTENT = 1100
WIA_IPS_XRES = 100
WIA_IPS_YRES = 100

Example 3: An application sets the WIA_IPS_ORIENTATION property to LANSCAPE

In the following code example, the minidriver changes the page orientation from portrait to landscape. The physical bed must be able to acquire a page that was originally in landscape orientation.

WIA_IPS_PAGE_SIZE = WIA_PAGE_LETTER
WIA_IPS_PAGE_HEIGHT = 11000
WIA_IPS_PAGE_WIDTH = 8500
WIA_IPS_ORIENTATION = LANSCAPE
WIA_IPS_XPOS = 0
WIA_IPS_YPOS = 0
WIA_IPS_XEXTENT = 1100
WIA_IPS_YEXTENT = 850
WIA_IPS_XRES = 100
WIA_IPS_YRES = 100

Example 4: An application changes the WIA_IPS_XEXTENT property to a smaller value

In the following code example, an application changes the WIA_IPS_XEXTENT property to 1000. The minidriver should assume that the new value that is contained in WIA_IPS_XEXTENT is no longer valid for the WIA_IPS_PAGE_SIZE property and should thus change WIA_IPS_PAGE_SIZE to WIA_PAGE_CUSTOM. The minidriver must also adjust WIA_IPS_PAGE_WIDTH.

WIA_IPS_PAGE_SIZE = WIA_PAGE_CUSTOM
WIA_IPS_PAGE_HEIGHT = 10000
WIA_IPS_PAGE_WIDTH = 8500
WIA_IPS_ORIENTATION = LANSCAPE
WIA_IPS_XPOS = 0
WIA_IPS_YPOS = 0
WIA_IPS_XEXTENT = 1000
WIA_IPS_YEXTENT = 850
WIA_IPS_XRES = 100
WIA_IPS_YRES = 100
