Hi I am able to read some 2d datamatrix barcode images downloaded from internet using Zxing library but not able to read images taken from my high resolution colored camera images. Now I am converting them into black and white images but still images are not readable. Can someone suggest me where I am doing wrong? I have attached some images here. Please help.



Thanks
These are white-on-black barcodes, and are not standard. The library doesn’t read them. You would have to invert the image.
