DataMatrixCodeParams

Description

Specifies range of possible data matrix codes.

Structure fields and default values (if defined) are described below:

Name	Type	Default	Description
Polarity	atl::Optional<CodePolarity>	Any	Specifies whether code is darker or brighter than the background
MinRowCount	int	8	Minimal number of module rows
MaxRowCount	int	72	Maximal number of module rows
MinColumnCount	int	8	Minimal number of module columns
MaxColumnCount	int	72	Maximal number of module columns
MinModuleSize	float	4	Minimal size of a module in pixels
MaxModuleSize	float	40	Maximal size of a module in pixels
ExpectedGapSize	atl::Optional<DataMatrixGapSize>	Small	Highest distance between neighboring marks in the Finder Pattern
MaxRectangleRatio	atl::Optional<float>	4.0f	Length ratio between the longer and the shorter side of the code's bounding rectangle
MaxSlant	float	20.0f	Maximal deviation from the right angle in the corner of the Finder Pattern
AllowPerspective	DataMatrixPerspectiveLevel	Low	Allows codes with perspective distortion (up to a certain level)
AllowOversizedModules	bool	true	Allows codes with foreground modules overlapping background modules
AllowRotation	bool	true	Allows codes rotated in relation to the axes of the input image
AllowDistortion	atl::Optional<DataMatrixDistortionLevel>	Low	Allows codes which are distorted
AllowBrokenTiming	bool	true	Tries to decode a candidate even if there is no correct Timing Pattern
AllowBrokenFinder	bool	true	Tries to create a candidate even if there are gaps in the Finder Pattern
AllowBrokenCorner	bool	true	Tries to create a candidate even if the bottom-left corner of the code is occluded.
AllowMirrored	bool	false	Allows codes to be mirrored/transposed.
