Detailed Description

ImageReadAccessor class to get locked read access for a particular image part.

Definition at line 31 of file mitkImageReadAccessor.h.

Member Typedef Documentation

Definition at line 39 of file mitkImageReadAccessor.h.

mitk::ImageReadAccessor::ImageReadAccessor	(	ImageConstPointer	image,
		const ImageDataItem *	iDI = `nullptr`,
		int	OptionFlags = `ImageAccessorBase::DefaultBehavior`
	)

Orders read access for a slice, volume or 4D-Image.

Parameters

Image::Pointer	specifies the associated Image
ImageDataItem*	specifies the allocated image part
OptionFlags	properties from mitk::ImageAccessorBase::Options can be chosen and assembled with bitwise unification.

Exceptions

mitk::Exception	if the Constructor was created inappropriately
mitk::MemoryIsLockedException	if requested image area is exclusively locked and mitk::ImageAccessorBase::ExceptionIfLocked is set in OptionFlags
