Visualize RGB

Class: NodeImageVisualizeRGB

Node Icon

Sometimes the provided colormaps are not sufficient when displaying the colors of an image. This node can visualize three images as the red, green and blue channels of an RGB image. The inputs can be three separate R, G, and B images, a vector image where the vector components x, y and z will be shown as the red, green and blue channels respectively; and a time series where the three frames will be displayed as red, green and blue respecively.

Example Workflows

Visualizer node example

Inputs

R

The red channel.

Type: Image4DFloat, Required, Single

G

The green channel.

Type: Image4DFloat, Required, Single

B

The blue channel.

Type: Image4DFloat, Required, Single

Settings

Input Type Selection

Select the input format of the RGB data.

If the R, G, and B channels are times series (or have multiple frames) they need to be supplied as separate R, G and B channels. The number number of frames of the R channel will determine the number of frames of the RGB image. If the G or B channels have fewer frames, the last frame will be repeated to match the red channel frame count.

Values: RGB, Frames, VectorField

Viewport Integer

Set the target viewport number.

Layer Integer

Set the layer in which the image or mask will be displayed. The bottom layer is layer 1.

Lock Viewport Boolean

Set to TRUE if you want to lock the viewport coordinate system to other viewports.

Window Min Number

Set the min value.

Window Max Number

Set the max value.

Slice Integer

Select the slice to display. A slice of 0 means the middle slice will be selected.

Frame Integer

Select the frame to display.

Orientation Selection

Select the projection of the image, which can be axial (AX), sagittal (SAG), coronal (COR) or a 3D rendering (XYZ).

Values: AX, SAG, COR, XYZ

Interpolation Selection

Set the image interpolation.

Values: Cubic, Linear, Nearest
