Asynchronously gets the image information about a specific page from a stream containing image data.
public static Task<CodecsImageInfo> GetInformationAsync(
this RasterCodecs rasterCodecs,
ILeadStream stream,
bool totalPages,
int pageNumber
)
rasterCodecs
RasterCodecs object to perform the operation.
stream
Stream containing the input image data to query.
totalPages
true to query the file for total number of pages; false, otherwise.
pageNumber
The page number to query. Pass 1 for the first page (default).
A Task
that represents the asynchronous operation. TResult
: CodecsImageInfo object that contains the information about the specified image. See remarks about the usage of this object.
This topic is part of RasterCodecs
support for .NET async/await
support. Refer to RasterCodecs Async Operations for more information.
Specifying true for totalPages can cause the process to be slow for files with large number of pages.
The RasterCodecs class supports getting information on image files asynchronously using the GetInformationAsync methods.
For .NET Framework: A reference to the Leadtools.Async.dll assembly is required to use this functionality.
For .NET Standard: This functionality is included in the Leadtools.Codecs.dll assembly.
