View PDF

ImagXpress® can be used in conjunction with PDF Xpress™ to display PDF pages. Assign bitmaps rendered using PDF Xpress to an ImagXpress ImageXView object to leverage its image-viewing features.

To view a PDF document page:

Create a Document for an existing PDF document.
Invoke RenderOptionsToBitmap to produce a System.Drawing.Bitmap for an area on the page, at a target device resolution.
Create an ImageX object with ImageX.FromBitmap using the rendered System.Drawing.Bitmap.
Assign to the ImageXView property Image the new ImageX object.
