we know that the true color map contains up to 2^24 color, how to choose 256 colors, but also make the color distortion is relatively small, this is a more complex problem. A simple practice is to r:g:b in 3:3:2, that is, take r,g high 3 bits, b high two bits, composed of a byte, so it can represent 256 colors, but it is not difficult to imagine that this method of distortion is certainly very serious.The a

We often say that Windows 95/98 is in a 16 or 256 color state, which means the maximum number of colors displayed on the screen. You can see that it is normal to display black-and-white text or simple color lines in 16 colors, but if we want to see more than 16 colors, you have to use 256 or more colors. That is to say, you need to set the display mode to a high color state. For each pixel on the screen,

Most of the time we write an ASP that will take a minute or even a few minutes because it does a lot of work. To enable software users to wait patiently for the execution of a program, we often want a progress bar to represent the state of the program execution. Or at the very least, display descriptive text such as "Data Loading", "Saving data", and so on. At this point we will use the Response.Flush (). He will send the data compiled in the buffer to the client first.But there are times when w

Why do I have to implement the go aes-cbc-256 encryption and decryption function? The previous project was implemented using PHP. Now we are going to use go for reconstruction. This function is required. This common feature allows us to search for a ready-made example on the Internet, so you can implement a pair of encryption and decryption functions in minutes based on the existing go API. If you think right, it will fail when you run it. Well, there

Micro framework provides the ability to access the Internet. In terms of data security, micro framework only supports RSA and xtea algorithms. Due to the communication needs of heterogeneous systems, I have compiled an Encryption Class Library, which currently only implements SHA-1, SHA-256 algorithm, and will be improved later. See http://www.microframework.cn/post/2009/03/16/SHA-Algorithms-On-Micro-Framework.aspx The code can be downloaded here: s
