ImageCodecInfo Class

ImageCodecInfo Class

An ImageCodecInfo object stores information about an image codec (encoder/decoder). GDI+ provides several built-in image codecs. You can obtain information about those codecs by calling the GetImageEncoders function and the GetImageDecoders function. Each of those functions returns an array of ImageCodecInfo objects, one for each available encoder or decoder.

ImageCodecInfo has the following types of members:

Data Members

The following table lists the members exposed by the ImageCodecInfo object.

Data Members	Type	Description
Clsid	CLSID	Codec identifier.
FormatID	GUID	File format identifier. GUIDs that identify various file formats (ImageFormatBMP, ImageFormatEMF, and the like) are defined in Gdiplusimaging.h.
CodecName	WCHAR *	Pointer to a null-terminated string that contains the codec name.
DllName	WCHAR *	Pointer to a null-terminated string that contains the path name of the DLL in which the codec resides. If the codec is not in a DLL, this pointer is NULL.
FormatDescription	WCHAR *	Pointer to a null-terminated string that contains the name of the file format used by the codec.
FilenameExtension	WCHAR *	Pointer to a null-terminated string that contains all file-name extensions associated with the codec. The extensions are separated by semicolons.
MimeType	WCHAR *	Pointer to a null-terminated string that contains the mime type of the codec.
Flags	DWORD	Combination of flags from the ImageCodecFlags enumeration.
Version	DWORD	Integer that indicates the version of the codec.
SigCount	DWORD	Integer that indicates the number of signatures used by the file format associated with the codec.
SigSize	DWORD	Integer that indicates the number of bytes in each signature.
SigPattern	BYTE *	Pointer to an array of bytes that contains the pattern for each signature.
SigMask	BYTE *	Pointer to an array of bytes that contains the mask for each signature.
