DetectDataMatrices_Deprecated
| Header: | FIL.h |
|---|---|
| Namespace: | fil |
Finds candidates for Data Matrix codes in the input image.
Syntax
C++
void fil::DetectDataMatrices_Deprecated ( const fil::Image& inImage, ftl::Optional<const fil::Region&> inRoi, bool inAllowRectangular, ftl::Array<fil::Rectangle2D>& outDataMatrixPositions )
Parameters
| Name | Type | Default | Description | |
|---|---|---|---|---|
 |
inImage | const Image& | Input image | |
|
inRoi | Optional<const Region&> | NIL | Range of pixels to be processed |
|
inAllowRectangular | bool | False | Enables detecting rectangular Data Matrices |
 |
outDataMatrixPositions | Array<Rectangle2D>& | Array of possible positions of Data Matrices |
Description
Supported code types: ECC 200 and ECC 000-140.
Around datamatrix must be quiet zone. The minimum quiet zone is equal to the width of a module on all four sides. For applications with moderate to excessive reflected noise in close proximity to the symbol, a quiet zone of 2 to 4 module widths is recommended.
