ICLCodec demonstrates how to implement encoder and decoder plug-ins for the Image Converter Library. A decoder converts an image in a particular format into a CFbsBitmap object; an encoder does the reverse. In the example, the Portable Network Graphics (PNG) format is handled.
The program is an ECom plug-in that implements:
the decoder plug-in interface CImageDecoderPlugin by the class CPngDecoder
the decoder data reader interface CImageReadCodec by the class CPngReadCodec
the encoder plug-in interface CImageEncoderPlugin by the class CPngEncoder
the encoder data writer interface CImageWriteCodec by the class CPngWriteCodec
The PNG format allows data to be stored in a number of different scanline formats (colour/grey-scale depths), so specialist classes are provided to read and write these formats. Scanline reader classes are derived from CPngReadSubCodec ; writer classes from CPngWriteSubCodec .
