J2K_Frames operators

J2K_Frames class has the following operators:

unsigned char* operator() (int no);

unsigned char* operator() ();
void operator= (int no);
void operator++ ();
void operator−− ();

Notes

1. operator() (int no) is similar to J2K_Frames::getFrame().

2. Last 4 operators use internal variable to store the current frame number. This allows J2K_Frames object to act as a simple iterator.

3. ++ or −− operators will 'wrap around', i.e. the current frame will go to 0 after the maximum number is reached and vice versa.

Example

J2K_Frames frms;

int j2k_err = frms.open("test.jp2", "mba");
if(j2k_err != J2KERR_SUCCESS){ printf("\n J2K-Codec error: %s.\n", frms.errStr); return -1; }

...

DrawFrame(x, y, frms()); frms++;
