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
A CodecsImageInfo object that contains the information about the specified image.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.
For authentical and proxy settings, refer to UriOperationCredentials and UriOperationProxy.
