Member Function Documentation

ChangeContrast

void DdtColourmapWidget::ChangeContrast ( ddt::colorMap_t colourmap, ddt::colorMap_t colourmap_inverted, ddt::colorMapARGB_t colourmap_argb, ddt::colorMapARGB_t colourmap_argb_inverted )

signal

Signal which is sent when the colourbar is changed by the user

InvertColourmap

void DdtColourmapWidget::InvertColourmap ( const bool invert )

protectedslot

Slot which is called when the colourmap was inverted

Parameters

invert

True if colourmap was inverted, false otherwise.

mouseMoveEvent()

void DdtColourmapWidget::mouseMoveEvent ( QMouseEvent * event )

final

mousePressEvent()

void DdtColourmapWidget::mousePressEvent ( QMouseEvent * event )

final

mouseReleaseEvent()

void DdtColourmapWidget::mouseReleaseEvent ( QMouseEvent * event )

final

Reset

void DdtColourmapWidget::Reset ( )

protectedslot

Slot which is called when the image in the image widget is cleared

RestoreColourmap

void DdtColourmapWidget::RestoreColourmap ( )

signal

Signal which is sent when the colourmap should be restored. This is triggered by pressing the mouse wheel on the colourbar.

SetCurrentColourmap

void DdtColourmapWidget::SetCurrentColourmap ( QVector< QRgb > colourmap )

protectedslot

Receive the current colourmap as qRGB vector

Parameters

colourmap

Vector of 255 RGB colour values

UpdateColourbarAxis

void DdtColourmapWidget::UpdateColourbarAxis ( double min_value, double max_value, int scaling_function )

protectedslot

Receive the current scaling function and minimum and maximum value for the scale

Parameters

min_value	Minimum pixel value used
max_value	Maximum pixel value used
scaling_function	The scaling function actively used
