// Functions related to accessing channels and views in multi-view
|
|
// OpenEXR files.
|
|
//
|
|
// A multi-view image file 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. Each view has its own
|
|
// set of image channels. A naming convention identifies the channels
|
|
// that belong to a given view.
|
|
//
|
|
// A "multiView" attribute in the file header lists the names of the
|
|
// views in an image (see ImfStandardAttributes.h), and channel names
|
|
// of the form
|
|
//
|
|
// layer.view.channel
|
|
//
|
|
// allow channels to be matched with views.
|
|
//
|
|
// For compatibility with singe-view images, the first view listed in
|
|
// the multiView attribute is the "default view", and channels that
|
|
// have no periods in their names are considered part of the default
|
|
// view.
|
|
//
|
|
// For example, if a file's multiView attribute lists the views
|
|
// "left" and "right", in that order, then "left" is the default
|
|
// view. Channels
|
|
//
|
|
// "R", "left.Z", "diffuse.left.R"
|
|
//
|
|
// are part of the "left" view; channels
|
|
//
|
|
// "right.R", "right.Z", "diffuse.right.R"
|
|
//
|
|
// are part of the "right" view; and channels
|
|
//
|
|
// "tmp.R", "right.diffuse.R", "diffuse.tmp.R"
|
|
//
|
|
// belong to no view at all.
