Remarks

The various RasterCodecs.GetInformation methods are used to return information about a raster image file on disk or stream. Information such as the format, size, dimension, bits per pixel are returned as members of the CodecsImageInfo object returned from RasterCodecs.GetInformation.

Raster Adobe PDF saved with the various Save methods (using any of the RasterImageFormat.RasPdfXyz flavors), contain extra information that can be obtained using RasterCodecs.GetRasterPdfInfo. This method returns an instance of CodecsRasterPdfInfo filled with these extra information. Refer to CodecsRasterPdfInfo for more information.
