// Class responsible for handling the writing of multipart images.

|
|
// Note: Certain attributes are 'common' to all parts. Notably:
|
|
// * Display Window
|
|
// * Pixel Aspect Ratio
|
|
// * Time Code
|
|
// * Chromaticities
|
|
// The first header forms the basis for the set of attributes that are shared

|
// across the constituent parts.
|

//
|
|
// Parameters
|
|
// headers - pointer to array of headers; one for each part of the image file
|
|
// parts - count of number of parts
|
|
// overrideSharedAttributes - toggle for the handling of shared attributes.
|
|
// set false to check for inconsistencies, true
|
|
// to copy the values over from the first header.
|
|
// numThreads - number of threads that should be used in encoding the data.
