Parameters

stream
Stream containing the input image data.

totalPages
true to query the file for total number of pages; false, otherwise.

pageNumber
Page number in the file to query.

Return Value

A CodecsImageInfo object that contains the information about the specified image.

Remarks

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

To quickly query the number of an image, use GetTotalPages or GetTotalPagesAsync.

To quickly query the format of an image, use GetFormat or GetFormatAsync.

Example

For an example, refer to GetInformation.
