public IAsyncOperation<IVector<LeadSize>> ReadLoadResolutionsAsync( 
   ILeadStream stream
)

'Declaration

Public Overloads Function ReadLoadResolutionsAsync( _
   ByVal stream As ILeadStream _
) As IAsyncOperation(Of IVector(Of LeadSize))

'Usage

Dim instance As RasterCodecs
Dim stream As ILeadStream
Dim value As IAsyncOperation(Of IVector(Of LeadSize))
 
value = instance.ReadLoadResolutionsAsync(stream)

public IAsyncOperation<IVector<LeadSize>> ReadLoadResolutionsAsync( 
   ILeadStream stream
)

 function Leadtools.Codecs.RasterCodecs.ReadLoadResolutionsAsync(ILeadStream)( 
   stream 
)

public:
IAsyncOperation<IVector<LeadSize>^>^ ReadLoadResolutionsAsync( 
   ILeadStream^ stream
)

Parameters

stream: A ILeadStream containing the data of the image file to query.

Return Value

When this method completes, it returns the available resolutions as an array of LeadSize structures.

Remarks

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).

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