Resolution of this page.
public double Resolution {get; set;}
The resolution of this DocumentPage, in dots per inch (DPI). The default value is 0.
If this DocumentPage corresponds to an original page in the document, then the resolution of the page is determined from the original document when LEADDocument is loaded. If this page was added to the document by the user, then the size is the value passed to DocumentPages.CreatePage.
OriginalPageNumber is the page number of this DocumentPage in the original document. It is -1 if this page was added by the user.
For more information, refer to Loading Using LEADTOOLS Document Library.
Some document types do not have a physical resolution. If the document type does not have a physical resolution, DocumentPages.DefaultResolution is used for all the initial values of the pages.
Size and Resolution will always contain values, and are populated for all pages of the document upon initialization. The LEADTOOLS Document Viewer relies on initialization to create empty items for each page in the image viewer control. Each item will have the correct size, but no image data. The Document Viewer will then load the raster image or SVG objects for the page in a background thread.
When the user sets a new raster image using SetImage, the Size and Resolution values of the page are updated from the RasterImage object. If the value passed is null, then the Size and Resolution will be updated using DocumentPages.DefaultPageSize and DocumentPages.DefaultResolution.
