◆ ImageReadAccessor() [1/3]

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::Pointerspecifies the associated Image
ImageDataItem*specifies the allocated image part
OptionFlagsproperties from mitk::ImageAccessorBase::Options can be chosen and assembled with bitwise unification.
Exceptions
mitk::Exceptionif the Constructor was created inappropriately
mitk::MemoryIsLockedExceptionif requested image area is exclusively locked and mitk::ImageAccessorBase::ExceptionIfLocked is set in OptionFlags
