[Rrdtool] Monitoring and automatic drawing, simple monitoring. md Now I want to monitor the traffic and concurrency of the service, but I don't have much time to write the system. Other O M systems are unfamiliar, therefore, the existing rrdtool shell is used for a simple monitoring interface. Temporary use is also a small experiment. Rrdtool is just getting s

object, the object will not take effect immediately. You must select the device description table to make it take effect in future painting operations. (4) Generally, after drawing, you must use the SelectObject function to select the previous GDI object into the device description table so that Restore to the previous status (5) When the width of the paint brush is less than or equal to 1, the dotted line is valid. (6) implementation code Cpen pen (

Author: Zhu Jincan Source: http://blog.csdn.net/clever101 Generally, in the drawing program, it is relatively simple to pick up the rectangle and the polygon. For example, in the crect and crgn classes of MFC, The ptinrect or ptinrgn function directly determines whether the vertex is in the graph. We pay attention to the way we pick up a line segment, because we generally use the width of a pixel to draw a

Learn the SDK and make a simple triangular drawing in d3d11 to familiarize yourself with the Direct11 drawing process. This article refers to the basic demo of the previous Directx11. The relatively Directx11 basic demo, which draws a triangle in Directx11, initializes the work primarily in Initdevice () 1: Create a vertex shader vertex shader;2: Describe our own

Recently, GDI + this thing contact more, also did some simple examples, such as drawing board, imitation QQ and so on. The first contact this class, is because want to do the effect of imitation QQ. Skillfully very, learned how to do it after that. NET classroom teacher also happened to talk about C # drawing knowledge, and I myself on the internet to learn the

Recently on GDI + this thing contact more, also did some simple examples, such as drawing board, imitation QQ screenshot.

Now want to monitor the traffic and concurrency of the service, but not so much time to write the system, the other operation and maintenance system is not familiar with, so the existing RRDtool shell made a simple monitoring interface, temporary use, but also a small experiment. RRDtool is also just contact, a little exercise ProcessThe approximate process is this (CENTOS6 operating system) Initializing the RRD database Shell script

This course is about drawing simple geometries, before actually drawing, let's familiarize ourselves with some concepts.point, Line, and PolygonWe know the concept of a bit, line, and polygon in math (specifically, geometry), but these concepts are different in computers.Math point, only position, no size. However, in a computer, no matter how precision is calcul

Recently, I have been reviewing the source code of Ffplay. Ffplay is an example of the player provided by the FFmpeg project. Although Ffplay is just a simple example of a player, the amount of its source code is quite a bit. The previous look at the code, mainly focused on a "point" for the study, but not from the overall structure of the analysis. This article intends to make up for the shortcomings of the previous study, from the overall structure

In the last piece has been introduced to you how to use GDI + to draw a simple image, this piece continues to introduce some other drawing knowledge. 1. First we look at the pen we used in the last piece. The properties of a pen are: color, dashcap (dash End shape), DashStyle (dash style), endcap (tail shape), startcap (thread shape), Width (thickness), etc. We can use a pen to draw dashed lines, straight

There is ways to draw basic shapes like circles, ovals, lines, arcs, squares, rectangles, rounded rectangles, and pol Ygons. Specific drawing methods like Graphics.drawOval() . This example uses these methods. The second is to construct a shape and then use to Graphics2D.draw() draw the shape. See the package for java.awt.geom examples that create shapes.Seee575The quintessential Drawing program public void
