Description

Details

ColorPacket

typedef struct {
  unsigned char red, green, blue;
  unsigned short index;
} ColorPacket;

A private structure used by the GIF conversion. It is usefull for all convertion from RGB to color table.

unsigned char red;

 red value ;

unsigned char green;

 green value ;

unsigned char blue;

 blue value.

unsigned short index;

Image

typedef struct {
  unsigned int columns, rows, colors;
  ColorPacket *colormap, *pixels, *packet;
  unsigned long packets;    
} Image;

A private structure used by the GIF conversion. It is usefull for all convertion from RGB to color table.

unsigned int columns;

 number of columns ;

unsigned int rows;

 number of rows ;

unsigned int colors;

 number of colours ;

ColorPacket *colormap;

 an array of colours ;

ColorPacket *pixels;

 the definition for each pixels ;

ColorPacket *packet;

 ??

unsigned long packets;

dumpToGif_quantizeImage ()

unsigned int        dumpToGif_quantizeImage             (unsigned int number_colors,
                                                         GString *buffer,
                                                         voidDataFunc functionWait,
                                                         gpointer data);

This routine transform an RGB image to an indexed colours image. To set the image to quantize, use setImage().

number_colors :

 the number of desired colours ;

buffer :

 a string to store some error messages ;

functionWait :

 a method that will be called during the quantize process ;

data :

 an argument to give to the wait function.

Returns :

dumpToGif_syncImage ()

void                dumpToGif_syncImage                 (void);

Do something in the GIF exoprt process.

dumpToGif_setImage ()

void                dumpToGif_setImage                  (Image *data);

Set the image to be manipulated by the GIF convertor (see dumpToGif_quantizeImage()).

data :

dumpToGif_init ()

DumpType*           dumpToGif_init                      ();

This routine should not be used since it inialised the module and is already called when V_Sim is launched.
