.SH NAME
wxQuantize \- 
  Class to perform quantization, or colour reduction
 
.SH DESCRIPTION

  


   Performs quantization, or colour reduction, on a wxImage.
  
  


   Functions in this class are static and so a wxQuantize object need not be
   created.

.SS  wxQuantize ()

     


      Constructor. You do not need to construct a wxQuantize object since its
      functions are static.
     
    
   
  
.SS bool Quantize (const wxImage& srcwxImage& destwxPalette** pPaletteint desiredNoColours = 236unsigned char** eightBitData = 0int flags = wxQUANTIZE_INCLUDE_WINDOWS_COLOURS|wxQUANTIZE_FILL_DESTINATION_IMAGE|wxQUANTIZE_RETURN_8BIT_DATA)

     


      Reduce the colours in the source image and put the result into the
      destination image. Both images may be the same, to overwrite the source
      image. Specify an optional palette pointer to receive the resulting
      palette. This palette may be passed to ConvertImageToBitmap, for example.
     
     


      If you pass a palette pointer, you must free the palette yourself.
     
    
.SS bool Quantize (const wxImage& srcwxImage& destint desiredNoColours = 236unsigned char** eightBitData = 0int flags = wxQUANTIZE_INCLUDE_WINDOWS_COLOURS|wxQUANTIZE_FILL_DESTINATION_IMAGE|wxQUANTIZE_RETURN_8BIT_DATA)

     


      This version sets a palette in the destination image so you don't have to
      manage it yourself.
     
    
   
  
.SS void DoQuantize (unsigned wunsigned hunsigned char** in_rowsunsigned char** out_rowsunsigned char* paletteint desiredNoColours)

     


      Converts input bitmap(s) into 8bit representation with custom palette.
     
     


      in_rows and out_rows are arrays [0..h-1] of pointer to rows (in_rows
      contains w * 3 bytes per row, out_rows w bytes per row).
     
     


      Fills out_rows with indexes into palette (which is also stored into
      palette variable).
