| virtual OFCondition | encode (Uint16 columns, Uint16 rows, EP_Interpretation interpr, Uint16 samplesPerPixel, Uint16 *image_buffer, Uint8 *&to, Uint32 &length)=0 |
| single frame compression routine for 16-bit raw pixel data. | |
| virtual OFCondition | encode (Uint16 columns, Uint16 rows, EP_Interpretation interpr, Uint16 samplesPerPixel, Uint8 *image_buffer, Uint8 *&to, Uint32 &length)=0 |
| single frame compression routine for 8-bit raw pixel data. | |
| virtual Uint16 | bytesPerSample () const =0 |
| returns the number of bytes per sample that will be expected when encoding. | |
| virtual Uint16 | bitsPerSample () const =0 |
| returns the number of bits per sample that will be expected when encoding. | |

pure virtual |
single frame compression routine for 16-bit raw pixel data.
May only be called if bytesPerSample() == 2.
| columns | columns of frame |
| rows | rows of frame |
| interpr | photometric interpretation of input frame |
| samplesPerPixel | samples per pixel of input frame |
| image_buffer | pointer to frame buffer |
| to | compressed frame returned in this parameter upon success |
| length | length of compressed frame (in bytes) returned in this parameter upon success; length guaranteed to be always even. |
Implemented in DJCompressIJG12Bit, DJCompressIJG16Bit, and DJCompressIJG8Bit.
