code

So you really want top get your hands dirty?
You know C++ by heart?

Be our guest!

Here is a sample of C++ code, on how to use our library:

#include <stdio.h>
#include <stdlib.h>
#include <stdarg.h>
#include <string.h>
#include "w3texlib.hpp"

// ---- Helper routines

// Various small support routines for .DDS saving and error reporting
// (not reproduced here for clarity)

// ---- Actual program

// Calc callback
static bool CalcCallback(int current,int max)
{  
  printf("rcalc... %3d%%",current*100/max);  
  return true; // return true unless you wish to abort calculation
}

int main()
{  
  static const char fileName[] = "demo.ktx";  

  W3TextureContext context;  
  unsigned char *data;  

  // load demo file  
  if(!(data = loadFile(fileName)))    
    errorExit("couldn't load data file '%s'!\n",fileName);  

  if(!context.Load(data))    
    errorExit("error in data file '%s'!\n",fileName);  

  // calculate everything  
  if(!context.Calculate(CalcCallback))    
    errorExit("error during calc.\n");  

  printf("\n");  

  // frees the document and associated data (only final images are left afterwards)  
  context.FreeDocument();  

  // save images  
  printf("saving images...\n");  for(int i=0;i<context.GetImageCount();i++)
  {
    const W3Image *img = context.GetImageByNumber(i);
    char namebuf[512];

    sprintf(namebuf,"%s.dds",context.GetImageName(i));
    saveImageDDS(img,namebuf);

    printf("%3d. %s\n",i+1,namebuf);
  }

  return 0;
}
