to think too much about getting a pixel of an image, but if you want to set a pixel, and the data type or bit width of the pixel is less than the width you want to set, you have to be aware of it, but it's safer to use the double setting and automatically convert it internally. You will see in the Java version of the OpenCV method in many places are using a doub

Introduction to Java NIO (iii) from theory to practice: using NIO to read and writeGuibin.beijing@gmail.com OverviewReading and writing are the most basic IO processing. Reading from a Channel is very simple. We only need to create a Buffer and then require the Channel to read data to the Buffer. Writing is also very s

exception is thrown when the put method is called. Areas not assigned a value in the buffer zone will be filled with 0. You can use the get method to obtain the data at the current position of the buffer and Add 1 to the current position of the buffer. Like the put method, when the current buffer location is equal to capacity, the get method will throw a java. NiO. bufferoverflowexception exception. The in

Boolean types in Java, the Boolean interface is actually discussed. However , the Boolean type that is so important and basic in the Java language does not exist substantively. Well, the joke is a bit big, there is a section In the JVM, the boolean operation of the source code is implemented as an int type operation of the JVM. The source code of the boolean[] type, whose elements are accessed and modified
