Parameters
field
The search field.
region
Region into the search field where the qr codes have to be found.
numCellsX
Number of grid cells in the X direction
numCellsY
Number of grid cells in the Y direction
extension
Extension of the grid cells to allow cell overlap. For instance, 0.0f means no extension and 0.1f means a 10% cell size extension.
area
Rectangular Region used as the full grid area
grid
Grid with cell disabling capabilities
Remarks
The grid overload allows you to disable some cells of the grid if those cells are not supposed to contain QR Codes. See the EQRCodeGrid class documentation for more information.
