Detailed Description
template<class TPixel, unsigned int VDimension = 3>
class mitk::ImagePixelWriteAccessor< TPixel, VDimension >
Gives locked and index-based write access for a particular image part. The class provides several set- and get-methods, which allow an easy pixel access. It needs to know about pixel type and dimension of its image at compile time.
- Template Parameters
-
TPixel defines the PixelType VDimension defines the dimension for accessing data

Constructor & Destructor Documentation
◆ ImagePixelWriteAccessor()
|
inline |
Instantiates a mitk::ImageWriteAccessor (see its doxygen page for more details)
- Parameters
-
iP specifies the associated Image iDI 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
Includes a check if typeid of PixelType coincides with templated TPixel and a check if VDimension equals to the Dimension of the Image.
- Note
- To avoid intermittent Update() calls to a predecessing filter pipeline, a call to Modified() method after the access is finished is left to the developer.
