In our daily surfing the Web page, often see some good-looking pictures, we would like to save these images to download, or users to do desktop wallpaper, or used to make design material.
Our most common practice is to choose Save as by right mouse button. But some pictures of the right mouse button is not saved as an option, there are ways to pass through the tool is intercepted, but this reduces the sharpness of the picture. All right ~! In fact,

Simple geometric images generally include points, lines, matrices, circles, ellipses, polygons, and so on. First of all, recognize OpenCV's definition of pixel points. One pixel of the image has 1 or 3 values, a grayscale value for the grayscale image, and a pixel value of 3 values for the color image, showing a different color.Then there is a point to make a variety of polygons.(i) Draw a line firstFunctio

Overall, I don't think it's as simple as writing a file system. The next thing to do is to add the encryption/decryption functionality to the script, as well as some help-class methods. My goal is to make it a complete alternative to ENCFS, in addition to having better scalability (written in
This article mainly introduces the Python implementation of a simple Httpserver server example, small series feel very good, and now share to everyone, but also for everyone to do a reference. Let's take a look at it with a little knitting.
