Hi Alun, Thanks for taking out time to reply .... i m generating the
raw data through this C program, it just generates a file with 12-bit
short values...i need to display it using JAVA

[C Code]

//----CODE STARTS-----//

#include <stdio.h>
#include <stdlib.h>
#include <alloc.h>

int main(void)
{

int i,numpix;
short *buf1, *buf2, *buf3, *buf4, *buf5, *buf6, *buf7, *buf8;

FILE *b1, *b2, *b3, *b4, *b5, *b6, *b7, *b8;

numpix = 3000;

buf1 = (short *) calloc(numpix, sizeof(short));
buf2 = (short *) calloc(numpix, sizeof(short));
buf3 = (short *) calloc(numpix, sizeof(short));
buf4 = (short *) calloc(numpix, sizeof(short));
buf5 = (short *) calloc(numpix, sizeof(short));
buf6 = (short *) calloc(numpix, sizeof(short));
buf7 = (short *) calloc(numpix, sizeof(short));
buf8 = (short *) calloc(numpix, sizeof(short));

b1 = fopen("b1.raw","wb");
b2 = fopen("b2.raw","wb");
b3 = fopen("b3.raw","wb");
b4 = fopen("b4.raw","wb");
b5 = fopen("b5.raw","wb");
b6 = fopen("b6.raw","wb");
b7 = fopen("b7.raw","wb");
b8 = fopen("b8.raw","wb");

for(i=0;i<numpix;i++){

  buf1[i]=0;

  buf2[i]=500;

  buf3[i]=1000;

  buf4[i]=1500;

  buf5[i]=2000;

  buf6[i]=2500;

  buf7[i]=3000;

  buf8[i]=3500;

}

for(i=0;i<=2000;i++){

  fwrite(buf1,sizeof(short),numpix,b1);
  fwrite(buf2,sizeof(short),numpix,b2);
  fwrite(buf3,sizeof(short),numpix,b3);
  fwrite(buf4,sizeof(short),numpix,b4);
  fwrite(buf5,sizeof(short),numpix,b5);
  fwrite(buf6,sizeof(short),numpix,b6);
  fwrite(buf7,sizeof(short),numpix,b7);
  fwrite(buf8,sizeof(short),numpix,b8);

}

fclose(b1);
fclose(b2);
fclose(b3);
fclose(b4);
fclose(b5);
fclose(b6);
fclose(b7);
fclose(b8);

free(buf1);
free(buf2);
free(buf3);
free(buf4);
free(buf5);
free(buf6);
free(buf7);
free(buf8);

return (0);

}

i m writing 8 files with different values...their resolution is 3000 x
2000

Thanx and Regards
