Get all Possible 1D BarCodes from an Image in Ruby

Aspose.BarCode - Get all Possible 1D Barcodes from an Image

To Get all Possible 1D Barcodes from an Image using Aspose.Barcode Java for Ruby, simply invoke GetAllOneDBarcodes module. Here you can see example code.

Ruby Code

 data_dir = File.dirname(File.dirname(File.dirname(File.dirname(__FILE__)))) + '/data/'

img = data_dir + "barcode.jpg"

\# initialize barcode reader

barcode_reader_type = Rjb::import('com.aspose.barcoderecognition.BarCodeReadType')

reader = Rjb::import('com.aspose.barcoderecognition.BarCodeReader').new(img, barcode_reader_type.Code39Standard)

\# Call read method

reader.read()

\# Now get all possible barcodes

barcodes = reader.getAllPossibleBarCodes()

i = 0

while i < barcodes.length

    # Display code text, symbology, detected angle, recognition percentage of the barcode

    puts "Code Text: " + barcodes[i].getCodetext().to_s + " Symbology: " + barcodes[i].getBarCodeReadType().to_s + " Recognition percentage: " + barcodes[i].getAngle().to_s

    # Display x and y coordinates of barcode detected

    point = barcodes[i].getRegion().getPoints()

    puts "Top left coordinates: X = " + point[0].getX().to_s + ", Y = " + point[0].getY().to_s

    puts "Bottom left coordinates: X = " + point[1].getX().to_s + ", Y = " + point[1].getY().to_s

    puts "Bottom right coordinates: X = " + point[2].getX().to_s + ", Y = " + point[2].getY().to_s

    puts "Top right coordinates: X = " + point[3].getX().to_s + ", Y = " + point[3].getY().to_s

    i +=1

end

\# Close reader

reader.close()
