Class representing different flavors of the Pixel Value Transformation FG:
- Pixel Value Transformation
- Identity Pixel Value Transformation
- CT Pixel Value Transformation The attributes in each type are always the same. Value checking is performed if possible for the selected FG type. Otherwise only logging is adapted where applicable.
FGPixelValueTransformation::FGPixelValueTransformation |
( |
| ) |
|
Constructor, creates (Identity) Pixel Value Transformation Functional Group.
All values (Rescale Slope, Intercept and Type) are initialized as if the class is used as the Identity Pixel Value Transformation FG, i.e. Rescale Slope is set to 1, Intercept to 0 and Type to "US".
virtual int FGPixelValueTransformation::compare |

const FGBase & |
rhs | ) |
const |
|
virtual |
Comparison operator that compares the normalized value of this object with a given object of the same type, i.e. the elements within both functional groups (this and rhs parameter) are compared by value! Both objects (this and rhs) need to have the same type (i.e. both FGUnknown) to be comparable.
This function is used in order to decide whether a functional group already exists, or is new. This is used in particular to find out whether a given functional group can be shared (i.e. the same information already exists as shared functional group) or is different from the same shared group. In that case the shared functional group must be distributed into per-frame functional groups, instead. The exact implementation for implementing the comparison is not relevant. However, it must be a comparison by value.
- Parameters
-
rhs | the right hand side of the comparison |
- Returns
- 0 if the object values are equal. -1 if either the value of the first component that does not match is lower in the this object, or all compared components match but this component is shorter. Also returned if this type and rhs type (DcmFGTypes::E_FGType) do not match. 1 if either the value of the first component that does not match is greater in this object, or all compared components match but this component is longer.
Implements FGBase.

This method is deprecated, use setFGType instead.
Tell this class that it should behave like the Identity Pixel Value Transformation Functional Group. This does not make a difference when reading data, but when writing, it is assured that Rescale Slope, Intercept and Type are forced to be set to 1, 0 and "US" respectively.
Denotes the represented functional group type.
E_PixelValTrans_Normal: Normal Pixel Value Transformation FG. No no special value requirements. E_PixelValTrans_Identity: Identity Pixel Value Transformation FG. Tells this class that it should behave like the Identity Pixel Value Transformation FG. This does not make a difference when reading data, but when writing, it is assured that Rescale Slope, Intercept and Type are forced to be set to 1, 0 and "US" respectively. E_PixelValTrans_CT: CT Pixel Value Transformation FG. Tells this class that it should behave like the CT Pixel Value Transformation FG. No special value requirements.
