// 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. |
|
