You are not passing the right parameters in, then. If you look at the  
code;

     if (rowstride == -1) {
         rowstride = width * 3;
     }
     if (rgb_buf_len < rowstride * (height-1) + width * 3) {
         php_error(E_WARNING, "RGB buffer is not large enough");
         return;
     }

Basically, your rowstride, width, and height parameters need to match  
up with the buffer length. And it also depends on whether you are  
using RGB or RGBA buffers.
