Parameters

uri

The Uri containing the input image data.

totalPages

true to query the URI for total number of pages, false otherwise.

pageNumber

Page number in the URI to query.

Return Value

Specifying true for totalPages can cause the process to be slow for files with large number of pages.

LEADTOOLS supports the following URI schemes:

Scheme	Description
UriSchemeFile	Specifies that the URI is a disk file in local machine or universal naming convention (UNC) path.
UriSchemeHttp	Specifies that the URI is accessed through the Hypertext Transfer Protocol (HTTP).
UriSchemeHttps	Specifies that the URI is accessed through the Secure Hypertext Transfer Protocol (HTTPS).
UriSchemeFtp	Specifies that the URI is accessed through the File Transfer Protocol (FTP).

If uri points to a resource in a UriSchemeHttp, UriSchemeHttps or UriSchemeFtp, then this RasterCodecs will attempt to download image data in an iterative fashion by creating a temporary buffer. The size of this buffer can be determined and changed by setting up the UriOperationBufferSize prior to calling this method.

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
