IWICBitmapEncoder interface (wincodec.h)
Defines methods for setting an encoder's properties such as thumbnails, frames, and palettes.
Inheritance
The IWICBitmapEncoder interface inherits from the IUnknown interface. IWICBitmapEncoder also has these types of members:
Methods
The IWICBitmapEncoder interface has these methods.
| IWICBitmapEncoder::Commit Commits all changes for the image and closes the stream. |
| IWICBitmapEncoder::CreateNewFrame Creates a new IWICBitmapFrameEncode instance. |
| IWICBitmapEncoder::GetContainerFormat Retrieves the encoder's container format. |
| IWICBitmapEncoder::GetEncoderInfo Retrieves an IWICBitmapEncoderInfo for the encoder. |
| IWICBitmapEncoder::GetMetadataQueryWriter Retrieves a metadata query writer for the encoder. |
| IWICBitmapEncoder::Initialize Initializes the encoder with an IStream which tells the encoder where to encode the bits. |
| IWICBitmapEncoder::SetColorContexts Sets the IWICColorContext objects for the encoder. |
| IWICBitmapEncoder::SetPalette Sets the global palette for the image. |
| IWICBitmapEncoder::SetPreview Sets the global preview for the image. |
| IWICBitmapEncoder::SetThumbnail Sets the global thumbnail for the image. |
Remarks
There are a number of concrete implementations of this interface representing each of the standard encoders provided by the platform including bitmap (BMP), Portable Network Graphics (PNG), Joint Photographic Experts Group (JPEG), Graphics Interchange Format (GIF), Tagged Image File Format (TIFF), and Microsoft Windows Digital Photo (WDP). The following table includes the class identifier (CLSID) for each native encoder.

| CLSID_WICTiffEncoder | 0x0131be10, 0x2001, 0x4c5f, 0xa9, 0xb0, 0xcc, 0x88, 0xfa, 0xb6, 0x4c, 0xe8 |
| CLSID_WICWmpEncoder | 0xac4ce3cb, 0xe1c1, 0x44cd, 0x82, 0x15, 0x5a, 0x16, 0x65, 0x50, 0x9e, 0xc2 |
Additionally this interface may be sub-classed to provide support for third party codecs as part of the extensibility model. See the AITCodec Sample CODEC.
CLSID_WICHeifDecoder operates on HEIF (High Efficiency Image Format) images.
