ReadLoadResolutionsAsync(ILeadStream) Method
Summary
Examines a stream to determine which resolutions it contains.
Syntax
public IAsyncOperation<IVector<LeadSize>> ReadLoadResolutionsAsync(ILeadStream stream)
Public Overloads Function ReadLoadResolutionsAsync( _ByVal stream As ILeadStream _) As IAsyncOperation(Of IVector(Of LeadSize))
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:
- CodecsJbigLoadOptions.Resolution
- CodecsJpeg2000LoadOptions.J2kResolution
- CodecsJpeg2000LoadOptions.CmwResolution
- CodecsFpxLoadOptions.Resolution
- CodecsPcdLoadOptions.Resolution
- CodecsEcwLoadOptions.Resolution
