AztecGenerator

public AztecGenerator()

Method Details

renderImage

public static GrayU8 renderImage(int pixelPerSquare,
 int border,
 AztecCode marker)

Convenience function for rendering images

render

public AztecGenerator render(AztecCode marker)

locatorPattern

protected void locatorPattern(double tl_x,
 double tl_y,
 int ringCount,
 AztecPyramid locator)

Renders the locator pattern given it's top-left corner of the outermost ring. This does NOT include the orientation pattern.

orientationPattern

protected void orientationPattern(double tl_x,
 double tl_y,
 int moduleCount)

referenceGridLine

protected void referenceGridLine(int tl_x,
 int tl_y,
 int dx,
 int dy,
 int count)

computeDataBitCoordinates

public static void computeDataBitCoordinates(AztecCode marker,
 PackedArrayPoint2D_I16 coordinates)

Computes the coordinate of each bit in the marker in units of squares as specified in Figure 5. Coordinate system will have (0, 0) be the marker's center. +x right and +y down.

Parameters:

coordinates - Coordinates are encoded as interleaved (row, col)

setMarkerWidth

public AztecGenerator setMarkerWidth(double width)

setRender

public AztecGenerator setRender(FiducialRenderEngine render)
