Detailed Description

Configures the display options for 2D slice rendering of images.

2D display options are mainly consumed by GlSlice which implements 2D rendering of image data. Usually, DisplayOptions2d are attached as a DataComponent to the image for which they define the rendering options. However, classes like ImageView2D may use special (e.g. view-specific) display options for rendering their images and therefore use the same interface.

Note

Window/level parameters are defined in original pixel value domain (e.g. Hounsfield Units). Conversion of pixel values to display intensities is performed using the LINEAR_EXACT VOI LUT function as described in section C.11.2.1.3.2 of the DICOM standard. http://dicom.nema.org/medical/dicom/current/output/chtml/part03/sect_C.11.2.html#sect_C.11.2.1.3

Member Enumeration Documentation

MaskingMode

enum class MaskingMode

strong

Enumeration of options for how masked image pixels should be rendered.

Enumerator
Ignore	Ignore the mask, render the pixels normally.
Discard	Discard masked pixels (where the mask value is 0)
AdditiveBlend	Add maskingColor() to masked pixels (where the mask value is 0)
MultiplicativeBlend	Multiply masked pixels with the maskingColor() (where the mask value is 0)
DiscardZerosAdditiveOnes	Discard pixels where the mask value is 0, add maskingColor() to pixels where the mask value is 1.
DiscardZerosMultiplicativeOnes	Discard pixels where the mask value is 0, multiply pixels with maskingColor() where the mask value is 1.

Constructor & Destructor Documentation

DisplayOptions2d()

DisplayOptions2d ( const Data * data )

explicit

Standard constructor for the given data.

Note

If data is not null and a SharedImageSet, window/level will be initialized to match the value range of the underlying image type without considering any actual pixel data. In all other cases it will be initialized to match a value range of [0..255].

Member Function Documentation

id()

std::string id ( ) const

overridevirtual

Returns a unique string identifier for this type of data component.

Note

To avoid conflicts make sure to include potential plugin names into this ID. Due to the modular architecture of the ImFusion library, uniqueness of IDs cannot be checked at compile time. However, DataComponentFactory will check the uniqueness of the ID during registration.

Implements DataComponentBase.

configure()

void configure ( const Properties * p )

overridevirtual

Configure this object instance by de-serializing the given Properties.

The default implementation will do so automatically for all registered Parameter and SubProperty instances.

Reimplemented from Configurable.

configuration()

void configuration ( Properties * p ) const

overridevirtual

Serialize the current object configuration into the given Properties object.
