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 |
---|---|
System.Uri.UriSchemeFile | Specifies that the URI is a disk file in local machine or universal naming convention (UNC) path. |
System.Uri.UriSchemeHttp | Specifies that the URI is accessed through the Hypertext Transfer Protocol (HTTP). |
System.Uri.UriSchemeHttps | Specifies that the URI is accessed through the Secure Hypertext Transfer Protocol (HTTPS). |
System.Uri.UriSchemeFtp | Specifies that the URI is accessed through the File Transfer Protocol (FTP). |
If uri points to a resource in a System.Uri.UriSchemeHttp, System.Uri.UriSchemeHttps or System.Uri.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.
For authenticity and proxy settings, refer to UriOperationCredentials and UriOperationProxy.
