getImageLoadRequests()

getImageLoadRequests(priority): object[]

It returns the imageLoad requests for the streaming image volume instance. It involves getting all the imageIds of the volume and creating a success callback which would update the texture (when the image has loaded) and the failure callback. Note that this method does not execute the requests but only returns the requests. It can be used for sorting requests outside of the volume loader itself e.g. loading a single slice of CT, followed by a single slice of PET (interleaved), before moving to the next slice.

Parameters

• priority: number

Returns

object[]

Array of requests including imageId of the request, its imageIdIndex, options (targetBuffer and scaling parameters), and additionalDetails (volumeId)
