Is their any way to retrieve the image buffer ( data )after reading it ?! In other words i need the unsigned char* of the image.

Image im;
im.read("test.bmp");

unsigned char * buf;

buf=?!

Thanks

Try writePixels():

• // Transfers one or more pixel components from the image pixel
  // cache to a buffer or file.
  // Used to support image encoders.
  void Magick::Image::writePixels ( const Magick::QuantumType quantum_,
  unsigned char *destination_ )
