Méthodes publiques

Méthode	Description
GetImageEncoderFromMimeType ( string mimeType ) : System.Drawing.Imaging.ImageCodecInfo	Gets the appropriate ImageCodecInfo based on a mime type
GetImageFormatFromMimeType ( string mimeType ) : ImageFormat	Get the appropriate ImageFormat for the specified mimeType using GetImageEncoderFromMimeType as a helper.
IsBmp ( Stream stream ) : bool	Looks for the BMP 2-byte leading signature at the current position in the stream. Rewinds the stream to its original position when finished.
IsGif ( Stream stream ) : bool	Looks for the GIF 6-byte leading signature and version the current position in the stream. Rewinds the stream to its original position when finished.
IsImageType ( Stream stream, ImageFormat type ) : bool	Detects if the image in the given stream is
IsJpeg ( Stream stream ) : bool	Looks for the JPEG 2-bytes leading signature at the current position in the stream Rewinds the stream to its original position when finished.
IsPng ( Stream stream ) : bool	Looks for the PNG 8-byte leading signature at the current position in the stream. Rewinds the stream to its original position when finished.
