Detailed Description

An abstract class used to encapsulate different mask pattern class definitions.

This pure abstract class will help to encapsulate different pattern masks. It defines common public methods TRestPatternMask::GetRegion and TRestPatternMask::HitsPattern that allow to identify the region were a (x,y) coordinate was found, or if has hitted the pattern structure defined at the inherited class.

Note: The mask will always be centered at (0,0). The offset applied in this class will only affect the pattern. Any global offset needs to be introduced externally.

The rotation members are stored in this class to allow a common definition of rotation and translation parameters for any pattern.

Parameters

The following parameters are common to any TRestPatternMask.

offset: A parameter to shift the pattern window mask.
rotationAngle: An angle given in radians to rotate the pattern.
maskRadius: A radius defining the limits of the circular mask. If it is equal to zero, the mask has no limits.

The inherited class should implement the pure abstract method TRestPatternMask::GetRegion integrating the logic to identify regions and the pattern mask. The inherited GetRegion method implementation should call TRestPatternMask::ApplyCommonMaskTransformation to define mask offset, rotation and radial limit.

Some examples are : TRestGridMask, TRestStrippedMask, TRestSpiderMask and TRestRingsMask. More details on each class documentation.

Constructor & Destructor Documentation

◆ TRestPatternMask()

TRestPatternMask::TRestPatternMask	(	const char *	cfgFileName,
		std::string	name = `""`
	)

Constructor loading data from a config file.

If no configuration path is defined using TRestMetadata::SetConfigFilePath the path to the config file must be specified using full path, absolute or relative.

The default behaviour is that the config file must be specified with full path, absolute or relative.

Parameters

cfgFileName	A const char* giving the path to an RML file.
name	The name of the specific metadata. It will be used to find the corresponding TRestAxionMagneticField section inside the RML.

◆ ApplyCommonMaskTransformation()

Int_t TRestPatternMask::ApplyCommonMaskTransformation	(	Double_t &	x,
		Double_t &	y
	)

protected

It produces an effective mask rotation and translation for the point x,y.

Remark: The window is centered, it is just the pattern that we want to shift.

◆ DrawMonteCarlo()

TCanvas * TRestPatternMask::DrawMonteCarlo ( Int_t nSamples = 10000 )

It generates a Monte Carlo with positions and paints them the returned canvas. Each unique region is associated with different colors. If there are too many colors, they might be repited for different region ids.
