// wrapmodes -- determines how texture map images are extrapolated.
// If an OpenEXR file is used as a texture map for 3D rendering,
// texture coordinates (0.0, 0.0) and (1.0, 1.0) correspond to
// the upper left and lower right corners of the data window.
// If the image is mapped onto a surface with texture coordinates
// outside the zero-to-one range, then the image must be extrapolated.
// This attribute tells the renderer how to do this extrapolation.
// The attribute contains either a pair of comma-separated keywords,
// to specify separate extrapolation modes for the horizontal and
// vertical directions; or a single keyword, to specify extrapolation
// in both directions (e.g. "clamp,periodic" or "clamp").  Extra white
// space surrounding the keywords is allowed, but should be ignored
// by the renderer ("clamp, black " is equivalent to "clamp,black").
// The keywords listed below are predefined; some renderers may support
// additional extrapolation modes:
//
//	black		pixels outside the zero-to-one range are black
//
//	clamp		texture coordinates less than 0.0 and greater
//			than 1.0 are clamped to 0.0 and 1.0 respectively
//
//	periodic	the texture image repeats periodically
//
//	mirror		the texture image repeats periodically, but
//			every other instance is mirrored
//

IMF_STD_ATTRIBUTE_DEF (wrapmodes, Wrapmodes, std::string)


//
// framesPerSecond -- defines the nominal playback frame rate for image
// sequences, in frames per second.  Every image in a sequence should
// have a framesPerSecond attribute, and the attribute value should be
// the same for all images in the sequence.  If an image sequence has
// no framesPerSecond attribute, playback software should assume that
// the frame rate for the sequence is 24 frames per second.
//
// In order to allow exact representation of NTSC frame and field rates,
// framesPerSecond is stored as a rational number.  A rational number is
// a pair of integers, n and d, that represents the value n/d.
//
// For the exact values of commonly used frame rates, please see header
// file ImfFramesPerSecond.h.
//

IMF_STD_ATTRIBUTE_DEF (framesPerSecond, FramesPerSecond, Rational)


//
// multiView -- defines the view names for multi-view image files.
// A multi-view image contains two or more views of the same scene,
// as seen from different viewpoints, for example a left-eye and
// a right-eye view for stereo displays.  The multiView attribute
// lists the names of the views in an image, and a naming convention
// identifies the channels that belong to each view.
//
// For details, please see header file ImfMultiView.h
//

IMF_STD_ATTRIBUTE_DEF (multiView , MultiView, StringVector)


// 
// worldToCamera -- for images generated by 3D computer graphics rendering,
// a matrix that transforms 3D points from the world to the camera coordinate
// space of the renderer.
// 
// The camera coordinate space is left-handed.  Its origin indicates the
// location of the camera.  The positive x and y axes correspond to the
// "right" and "up" directions in the rendered image.  The positive z
// axis indicates the camera's viewing direction.  (Objects in front of
// the camera have positive z coordinates.)
// 
// Camera coordinate space in OpenEXR is the same as in Pixar's Renderman.

// 
// worldToNDC -- for images generated by 3D computer graphics rendering, a
// matrix that transforms 3D points from the world to the Normalized Device
// Coordinate (NDC) space of the renderer.
// 
// NDC is a 2D coordinate space that corresponds to the image plane, with
// positive x and pointing to the right and y positive pointing down.  The
// coordinates (0, 0) and (1, 1) correspond to the upper left and lower right
// corners of the OpenEXR display window.
// 
// To transform a 3D point in word space into a 2D point in NDC space,
// multiply the 3D point by the worldToNDC matrix and discard the z
// coordinate.
// 
// NDC space in OpenEXR is the same as in Pixar's Renderman.
// 

IMF_STD_ATTRIBUTE_DEF (worldToNDC, WorldToNDC, IMATH_NAMESPACE::M44f)


//
// deepImageState -- specifies whether the pixels in a deep image are
// sorted and non-overlapping.
//
// Note: this attribute can be set by application code that writes a file
// in order to tell applications that read the file whether the pixel data
// must be cleaned up prior to image processing operations such as flattening. 
// The OpenEXR library does not verify that the attribute is consistent with
// the actual state of the pixels.  Application software may assume that the
// attribute is valid, as long as the software will not crash or lock up if
// any pixels are inconsistent with the deepImageState attribute.
