DataMatrixCodeParams

Description

Specifies range of possible data matrix codes.

Structure Fields

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

Name	Type	Default	Description
Polarity	Polarity	Any	Specifies whether code is darker or brighter than the background
MinRowCount	Integer	8	Minimal number of module rows
MaxRowCount	Integer	32	Maximal number of module rows
MinColumnCount	Integer	8	Minimal number of module columns
MaxColumnCount	Integer	32	Maximal number of module columns
MinModuleSize	Real	4	Minimal size of a module in pixels
MaxModuleSize	Real	40	Maximal size of a module in pixels
ExpectedGapSize	DataMatrixGapSize	Small	Highest distance between neighboring marks in the Finder Pattern
MaxRectangleRatio	Real*	4.0f	Length ratio between the longer and the shorter side of the code's bounding rectangle
MaxSlant	Real	20.0f	Maximal deviation from the right angle in the corner of the Finder Pattern
AllowPerspective	Bool	true	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	DataMatrixDistortionLevel	Low	Allows codes which are distorted
AllowBrokenTiming	Bool	true	Tries to decode a candidate even if there is no correct Timing Pattern
