the width of each module, and then you can calculate how many of the four edges of each module. This allows you to calculate the aspect ratio of the symbol to determine whether it is a rectangle or a square. Finally, the same as the QR code, using Samplegrid for the perspective transformation and sampling transformation, the original image of the symbol image correction, transformation for us to decode the required rules, in the module of the symbol matrix.

Often meet customers request us to recommend a cost-effective barcode printer. In fact, the well-known brands of bar code printers in terms of quality generally not very large, mainly based on your use of the situation, there are industrial machines and commercial machines, the price of more than 1000 to tens of thousands of. In general, it is OK to use, but after long-term use can know which is more durable, if it is industrial use of the proposed Ze

This article turned from programming blog: http://program-think.blogspot.com/2009/03/producer-consumer-pattern-0-overview.html Today we will introduce the "producer/consumer model", which can be used in many development fields.

Overview The message system is usually composed of producer, consumer, broker, the producer will write the message to the broker, the consumer will read out the message from the broker, the different MQ implementation of the broker implementation will be different, But the essence of broker is to be responsible for landing the

Preface: Recently in learning Java Multi-threading, see Importnew Online has a netizen translation of an article "block queue to achieve producer consumer model". In this article, the blocking queue in Java's concurrent package is used. After reading, implement the blocking queue by itself.(i) PreparationIn multi-threading, producer-consumer issues are a classic multithreaded synchronization issue. In short

thread that uses a class of resources (represented by class goods) is called the consumer consumer, and the thread that produces the same resource is called producer. To enable consumer and producer to work together, they should follow the following rules:(1) The producer producer can store the resources as long as bu

queue in a producer does not cause the get () method to return an error. 3 Q.join_thread (): The background thread that connects the queue. This method is used to wait for all queue items to be consumed after the Q.close () method is called. By default, this method is called by all processes that are not the original creator of Q. Calling the Q.cancel_join_thread method can prohibit this behaviorApplication:The multiprocessing module supports two mai
