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

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

Some simple applications for animations. Here is an example of drawing a straight line.The method of drawing is in DrawRectExecuted, the DrawRect method is similar to Cellforrowatindexpath, and can be executed directly by the system without calling in initWithFrame or Viewdidload.Below, draw an irregular line, the necessary code1-(void) DrawRect: (cgrect) rect{2S

I have already introduced to you how to use GDI + to draw, and made a screenshot of the example, this article I would like to introduce you to do a similar tool for Windows drawing.

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
