Remarks

If this DocumentPage corresponds to an original page in the document, then the resolution of the page is determined from the original document when Document was 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.

Refer to Loading Using LEADTOOLS Documents Library for more information.

Some document types do not have a physical resolution, in this case, DocumentPages.DefaultResolution is used for all the initial values of the pages.

Size and Resolution will always contain a value and is populated for all pages of the document upon initialization. The LEADTOOLS Document Viewer relies on this to create empty items for each page in the image viewer control. Each item will have the correct size but no image data. It will then loads 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 Size and Resolution will be updated using DocumentPages.DefaultPageSize and DocumentPages.DefaultResolution.

Example

For an example, refer to DocumentPage.
