DatacodeParams
Description
Specifies range of possible data matrix codes.Structure fields and default values (if defined) are described below:
Name | Type | Default | Description |
---|---|---|---|
Polarity | ftl::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 | ftl::Optional<DatacodeGapSize> | Small | Highest distance between neighboring marks in the Finder Pattern |
MaxRectangleRatio | ftl::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 | DatacodePerspectiveLevel | 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 | ftl::Optional<DatacodeDistortionLevel> | 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. |
