Purpose¶

The module SoView2DAnnotation displays general and configurable image information in a 2D viewer.

Details¶

The following keywords are available in the annotation text (written as $(variablename)):

Variable	Description
timepoint	The current temporal position.
timepointPlus1	Above plus one.
userIndex	The current user index.
slice	The current slice.
slicePlus1	Above plus one.
numSlices	The total number of slices.
sliceThickness	The thickness of the slice in mm.
min	The minimum voxel value of the dataset.
max	The maximum voxel value of the dataset.
zoom	The current zoom (zoom == 1 means one pixel per voxel).
type	The datatype of the image.
status	The status string of the SoView2D.
size[xyzctu]	The size of the dataset in x,y,z,c,t,u dimension (in voxel).
page[xyzctu]	The page size of the dataset in x,y,z,c,t,u dimension (in voxel).
voxel[xyz]	The voxel size of the dataset in x,y,z dimension (in mm).
input[00-09]	The string value of the `input00`- `input09` fields.
numInput[00-09]	The numerical value of the `numInput00`- `numInput09` fields.
userInfo	A string associated with the current SoView2D. See `SoView2D.userInfo`.
lutSize	The size of the used LUT.
shader	The active shader (GLSL, or empty if no shader is used).
distanceToCenterSlice	In case of mosaic views, that displays the distance (in mm ) to the center slice.
distanceToCenterSliceCM	In case of mosaic views, that displays the distance (in mm ) to the center slice.

In addition to these variables, any DICOM tag name can be specified, e.g., $(PatientsName).

One can specify a maximum displayed string length (for string values) or the decimal precision (for numerical values) by specifying an additional number after the variable name like this: $(variablename:number). If not given, a variable-specific default is applied.

Interaction¶

Key	Function
A	Toggles `Show Annotation` modes.
I	Toggles image information.

Tips¶

This module may be be used to display information on a 3D viewer as well by using a dummy SoView2D that does not render the image. To facilitate orientation and scale determination of a 3D viewer, the field orientationAndScaleFromCamera on the automatic panel can be enabled, which will take the Open Inventor viewing matrix to determine the orientation (used for orientation letters and orientation cube) and which will render the rulers correctly when an orthographic camera is used. Rulers are automatically disabled for perspective cameras.
