fast::ImageRenderer class

Renders 2D Image data objects, both in 2D and 3D.

Base classes

class Renderer virtual

Derived classes

class HeatmapRenderer
Renders Tensor data objects as heatmaps.
class SegmentationRenderer
Renders 2D segmentation data.
class SliceRenderer
Renders a 2D image slice extracted from a 3D image.
class VectorFieldColorRenderer
Renders a vector field image using colors.

Function documentation

std::shared_ptr<ImageRenderer> fast::ImageRenderer::create(float level, float window, float opacity, bool applyTransformationsIn2D) override

Create instance.

Parameters
level
window
opacity Draw image with an opacity. Useful if you want to draw an image on top of another
applyTransformationsIn2D In 2D transformations (rotation/translation) are typically not applied. by setting this to true they will be applied.
Returns instance
