The visual form of iOS applications is usually driven by graphical elements. When designing and developing an application, you need different specifications for application icons, such as default.png pictures of different sizes, as well as preparing @1x and @2x graphics resources for the implementation of the UI. All of these graphic elements will make your product look more appealing, but the drawbacks are

size and location may be affected by, and font-size line-height word-spacing so on CSS properties. The CSS style of the icon's container may have an impact on the position of the icon, which is inconvenient to adjust.3, the use of the inconvenience. First, loading an icon Font with hundreds of icons, but using only a few of them, is a waste of load time. It is also inconvenient to make an icon font yourself and integrate the icons used in multiple ic

As you all know, Photoshop is an important application for editing bitmaps. In fact, Photoshop also has a very powerful ability to handle vector graphics. In this tutorial, I'll introduce you to the 10 most important features of Photoshop vector graphics. We'll learn how to use the Free pen tool, the rubber band featur

. Used to smooth the edges of the graphic to reduce the sawtooth sensation, or to make the graph look fuller and more delicate, we call it a sub-pixel (or subpixel, and, generally, in the field of screen display technology), as shown in the following figure. Figure 1-anti-aliasing sub-pixel While the official version of PS CS6 is not universal, take PS CS5 as an example, and we discuss how to make the

ScalableVectorGraphics (SVG) is a language that uses XML to describe two-dimensional graphics (SVG strictly follows the XML syntax ), the SVG feature set includes nested conversions, cut paths, alpha masks, and template objects. If you are interested, you may find it helpful to increase your html5SVG2D knowledge. Bitmap and vector graph Previously, all the images displayed in the browser, such as jpeg and

Even in the relatively tedious field of two-dimensional vector graphics, windows®presentation Foundation (WPF) will still require programmers to learn many new concepts. In WPF, drawing objects have been elevated to almost equal status with controls, often participating in layouts and receiving mouse, keyboard, and stylus input. In addition, graphics systems reta

vector graphics, such as moving, zooming, stacking, rotating and twisting. When you edit a graphic, you turn the instruction into the shape and color that is displayed on the screen, and you can often see the drawing process. Since all the vector graphics can be described mathematically, the computer can be arbitraril
