So the consumers should have similar computing power.
BARCODE PRODUCER APP ANDROID
However, if we use the PC and the Android devices together, it will decrease the performance since there is a performance gap between them and ZeroMQ will try to distribute messages evenly. One is equipped with Snapdragon 630 and the other is equipped with Unisoc T610. The consumer can also run on embedded devices like Raspberry Pi and mobile phones.ĭynamsoft Barcode Reader has an Android library and ZeroMQ has a pure Java implementation named JeroMQ, so it is easy to create an Android app which works as a consumer.Ī performance test on the same dataset mentioned above is done using two Android devices. We can see that by using the push/pull pattern with several consumers, the barcode reading performance can be greatly improved.
BARCODE PRODUCER APP WINDOWS 10
Here are the test results of different numbers of consumers running on a Windows 10 PC with an i5-10400 CPU: time ()) * 1000 - result print ( "Done in " + str ( elapsedTime ))Īn EAN13 barcode dataset containing 215 images is used. If result = decoded : elapsedTime = int ( time. localization_points result = points result = points result = points result = points result = points result = points result = points result = points result_dict = results return result_dict Create a C++ program which replies to decoding requestsĬreate a C++ project and include the Dynamsoft Barcode Reader SDK, ZeroMQ and jsoncpp by following their guides: DBR, cppzmq, jsoncpp. 2 We can use this pattern to create a decoding program in C++ and a calling program in Python. The request/reply pattern of ZeroMQ is much the same. In a client/server model, the client sends a request and the server replies to the request. Please select the operating system on which you. Barcode Studio prints the bar codes on any printer or saves them as images.
BARCODE PRODUCER APP SOFTWARE
This barcode creator software supports all common linear codes, all 2D-Codes and GS1-DataBar/RSS. Barcode Studio is the perfect tool for designing and creating barcodes. The request/reply pattern of ZeroMQ is suitable for this scenario. Download Barcode Studio - Barcode Maker Software.
Two processes written in two different languages can communicate with each other using ZeroMQ. Inter-Process Communication for Cross-Language Programming In this article, we are going to create two demo apps using the request/reply pattern and the push/pull pattern.Ĭredits to the pyzmq docs. Second, using its push/pull pattern, we can create a distributed barcode reading program which processes more than 25 images per second. For example, we can create a decoding program using the C++ library of Dynamsoft Barcode Reader (DBR) and call it in Python. First, using its request/reply pattern, we can do cross-language programming. ZeroMQ can be used in barcode decoding, as well. It supports common messaging patterns (pub/sub, request/reply, client/server and others) over a variety of transports (TCP, in-process, inter-process, multicast, WebSocket and more), making inter-process messaging as simple as inter-thread messaging.
ZeroMQ is a high-performance asynchronous messaging library, aimed at use in distributed or concurrent applications.
