Do these still need to be virtual?

[dsinclair, 2016/04/11 20:40:40]

Yes, there are subclasses of CCodec_ScanlineDecoder which implement these
methods.

+  virtual uint8_t* v_GetNextLine() = 0;
+
+  uint8_t* ReadNextLine();
+
+  int m_OrigWidth;
+  int m_OrigHeight;
+  int m_OutputWidth;
+  int m_OutputHeight;
+  int m_nComps;
+  int m_bpc;
+  uint32_t m_Pitch;
+  int m_NextLine;
+  uint8_t* m_pLastScanline;
+};
