this is how implementation looks like


template<typename t="">
class Image
{
public:

void create(unsigned int width, unsigned int height)
{
_imageData = boost::shared_ptr<t>(new T[width * height]);
_width = width;
_height = height;
}

T getPixel(unsigned int x, unsigned int y) const
{
return _imageData[x * y];
}

void setPixel(unsigned int x, unsigned int y, T pixel)
{
_imageData[x + _width * y] = pixel;
}

// Return a sub-region of pixels
boost::shared_ptr<Image<t> > extractRegion(const Rectangle<t>& region) const
{
boost::shared_ptr<Image<t> > im = new Image<t>();

im->create(region.Width, region.Height);

for(unsigned int y = 0; y < region.Height; y++)
{
for(unsigned int x = 0; x < region.Width; x++)
{
im->setPixel(x, y, getPixel(region.X + x, region.Y + y));
}

}

return im;
}

private:

boost::shared_ptr<t> _imageData;

unsigned int _width;
unsigned int _height;


}
