Colormap class
Colormap data structure.
Contents
The colormap can be both in grayscale and in RGB color. The colormap can be linearly interpolated between points or just use nearest neighbor interpolation.
Public static functions
- static auto Ultrasound(bool grayscale = false) -> Colormap
Constructors, destructors, conversion operators
- Colormap()
- Create empty uninitialized colormap.
- Colormap(const std::map<float, float>& colormap, bool interpolate = true) explicit
- Create a grayscale colormap.
- Colormap(const std::map<float, Color>& colormap, bool interpolate = true) explicit
- Creates an RGB colormap.
- Colormap(std::vector<float> values, bool grayscale, bool interpolate = true)
- Creates a colormap directly from a list of floats.
Public functions

Function documentation
fast::
Create a grayscale colormap.
| Parameters | |
|---|---|
| colormap | |
| interpolate | |
fast::
Creates a colormap directly from a list of floats.
| Parameters | |
|---|---|
| values | |
| grayscale | |
| interpolate | |
The floats must be intensity_source1, intensity_output1, intensity_source2, intensity_output2, ... N if you have a grayscale colormap. If you have a RGB colormap it should be: intensity_source1, red1, green1, blue1, intensity_source2, red2, green2, blue2, .... N
cl::Buffer fast::
Create an OpenCL buffer from the colormap data.
| Parameters | |
|---|---|
| device | OpenCL device to transfer data to |
| Returns | OpenCL buffer |
std::vector<float> fast::
Get data values of the colormap as a list of floats.
| Returns | list of floats |
