public LeadSize[] readLoadResolutions(ILeadStream stream, int page)

 function Leadtools.Codecs.RasterCodecs.ReadLoadResolutions(Stream,Int32)( 
   stream ,
   pageNumber 
)

public:
array<LeadSize>^ ReadLoadResolutions( 
   Stream^ stream,
   int pageNumber
)

Parameters

stream: A Stream containing the data of the image file to query.
pageNumber: An Int32 that indicates the page number.

Return Value

A LeadSize structure containing the available resolutions.

A FlashPix, PhotoCD, ECW, JPEG 2000 or JBIG/JBIG2 file can contain more than one copy of the same image, each at a different physical resolution (width and height in pixels).

multi-page files (like TIF) containing compressions listed above (eg: JPEG 2000 or JBIG/JBIG2) can also contain more than one copy of the same image, each at a different physical resolution (width and height in pixels).

After you get the available resolutions, you can use any of the following to specify the one to be loaded:

The pages numbers start with 1, so set pageNumber to 2 to read the resolutions from the second page. If you set pageNumber to 1, the function behaves like the equivalent function without the pageNumber parameter.

After you get the available resolutions, you can use any of the following to specify the one to be loaded:
