Drawing Unnecessary efficiency considerations are often the root of the evils of performance problems. --william Allan Wulf In the 12th chapter, "Curvature of velocity" we learn how to use instruments to diagnose core animation performance problems. There are a number of potential performance pitfalls when building an iOS app, but in this chapter we'll look at performance issues related to

PowerPoint also allows you to design your own motion path. Select an object and select Add Effects Action path from the menu to draw a custom path, and then select a drawing method (such as a freeform curve) from the list. Then use the mouse to accurately map out the m

You can accurately position a picture or drawing object by using a grid, and you can change the size of a drawing object precisely. You can set up the drawing grid by following these steps: 1.

Today we use the form of animation to introduce the methods and techniques of drawing graphics. Depending on the needs of your presentation, you often draw some graphics in it, using the Drawing toolbar. 1. Execute the view → toolbar → drawing command to expand the Drawing

/*_______________________________________________________________ The principle of an animation is to draw/play images continuously. When you draw/play different expressions and a certain number of motion pictures per second, it is a visual illusion and a smooth animation effect will be displayed! With animation, an object has a soul and a life. Game object anal

It's an interesting little thing: using a custom view drawing, drawing lines, and drawing lines that fade until they disappear. The effect is shown in the following illustration: You can make a stroke of change with a property animation or a gradient fill (Shader), but if you want a gradient (the finger doesn't lift
