Since you're at it, have you considered making the API flexible enough 
so it could support vector images too?

	// return an object derived from image depending on the actual file type
	Image im = loadImage("filename");

	// creating a bitmap for on-screen rendering
	auto bitmap = new Bitmap!RGBColor(im.width, im.height);

	// base image class has a virtual function to draw itself on a bitmap at
	// a given location, so it's easy to draw it on screen
	im.draw(10, 10, bitmap);
