ImageSc

Namespace: DISPLIB  ·  Library: Display Library

#include <disp/imagesc.h>

class DISPLIB::ImageSc

False-colour heat-map QWidget visualising an Eigen matrix with selectable colour map.

Accepts MatrixXd, MatrixXf and MatrixXi inputs; init() rebuilds the cached QImage from the current matrix and the active colour map, and updateData() / paintEvent() keep the rendering in sync with the data.

Inheritance​

Public Methods​

ImageSc(parent)​

Creates the scaled image view.

Parameters:

  • parent : *QWidget ** Parent QObject (optional).

ImageSc(p_dMat, parent)​

Creates the scaled image view with a given double matrix.

Parameters:

  • p_dMat : Eigen::MatrixXd & The double data matrix.

  • parent : *QWidget ** Parent QObject (optional).

ImageSc(p_fMat, parent)​

Creates the scaled image view with a given float matrix.

Parameters:

  • p_fMat : Eigen::MatrixXf & The float data matrix.

  • parent : *QWidget ** Parent QObject (optional).

ImageSc(p_iMat, parent)​

Creates the scaled image view with a given integer matrix.

Parameters:

  • p_iMat : Eigen::MatrixXi & The integer data matrix.

  • parent : *QWidget ** Parent QObject (optional).

~ImageSc()​

Destructs the ImageSc object.

init()​

Initializes the ImageSc object.

updateData(p_dMat)​

Updates the scaled image view with a given double matrix.

Parameters:

  • p_dMat : Eigen::MatrixXd & The double data matrix.

updateData(p_fMat)​

Updates the scaled image view with a given float matrix.

Parameters:

  • p_fMat : Eigen::MatrixXf & The float data matrix.

updateData(p_iMat)​

Updates the scaled image view with a given integer matrix.

Parameters:

  • p_dMat The integer data matrix.

setColorMap(p_sColorMap)​

Sets the color map to use, e.g.

"Jet", "Hot", "Bone"

Parameters:

  • p_sColorMap : const QString & The colormap to use.
