RiImage

Stores an image of data corresponding to RiColorXYZV

class RiImage
{

public:
	RiImage();
	RiImage(int width, int height, RiReal fovDeg );
	RiImage(const RiImage &);
	~RiImage();
RiColorXYZV	operator()(int x, int y) const;
RiColorXYZV &	operator()(int x, int y);
int	GetWidth() const;
int	GetHeight() const;
RiReal	GetFieldOfView() const;
void	SetFieldOfView(RiReal fovDeg);
const RiImage &	operator=(const RiImage &);
void	Clear();

friend istream &	operator>>(istream &, RiImage &);

}; // RiImage

This representation of an image is used for RiColorXYZV images. There is no compression. The format is rough.

Construct a void/empty image

    RiImage();

age(int width, int height, RiReal fovDeg = 45); Initial image is not cleared. Use Clear for this.

    RiImage(int width, int height, RiReal fovDeg = 45);

Copy constructor WARNING: Very Expensive

    RiImage(const RiImage &);

clean up the image data.

    ~RiImage();

Get a pointer to the pixel value

    RiColorXYZV  	operator()(int x, int y) const;

Get a pointer to the pixel value

    RiColorXYZV	       &operator()(int x, int y);

Image Width (0 for an empty image)

    int	 	   GetWidth() const;

Image Height (0 for an empty image)

    int 	   GetHeight() const;

Total viewing angle in degrees for the width of the film plane.

    RiReal	   GetFieldOfView() const;

Total viewing angle in degrees for the width of the film plane.

    void	   SetFieldOfView(RiReal fovDeg);

assignment (deep copy all data)

    const RiImage &operator=(const RiImage &);

Clears the image (new images are not cleared)

    void	   Clear();

Write an image using PRIS format

    friend ostream &operator<<(ostream &, const RiImage &);

Read an image using PRIS format.

    friend istream &operator>>(istream &, RiImage &);

public:
RiColorXYZV	operator()(int x, int y) const;
RiColorXYZV &	operator()(int x, int y);
int	GetWidth() const;
int	GetHeight() const;
RiReal	GetFieldOfView() const;
void	SetFieldOfView(RiReal fovDeg);
const RiImage &	operator=(const RiImage &);
void	Clear();
friend ostream &	operator<<(ostream &, const RiImage &);
friend istream &	operator>>(istream &, RiImage &);
