Parameters

Name	Type	Description
index	Int32	An integer value, specifying the page number.
largestEdgeLength	Int32	An integer value, specifying the length of the image’s largest dimension.

BitmapSource	A System.Windows.Media.Imaging.BitmapSource object.

Remarks

The CreateBitmap method has two parameters: the converted page’s number and the length of the image’s largest dimension in pixels. The latter parameter determines the output image height for pages in the portrait orientation and width - for landscape pages.

You can reduce the output image size and memory consumption if you pass a smaller largestEdgeLength value to the CreateBitmap method. The document page will not be clipped when it is converted to bitmap. The page will be proportionally scaled so that the largest edge of the converted bitmap is equal to the largestEdgeLength value.
