* pixels: an array of pixels representing the datamatrix tag
* width: the width of the resulting pixels
* height: the height of the resulting pixels
* channels: the channels count of the resulting pixels$3
dmCreator.decodeDm({
cols: colsCount,
rows: rowsCount,
channels: channelsCount
}, data, timeout)
It returns an object with the following properties:
* success: true if a datamatrix tag was found and decoded properly
* test: the content of the datamatrix tag
