评分团队有项目将重度使用到canvas,但是个人对web图形并无太多了解。 断续花了几个周末把书看完。印象比较深的是1像素线的处理,精灵的制作,通过时间轴扭曲来制作缓动动画,碰撞检测,以及cavas性能优化的原则。 看过之后对市面上常见的web 2d图形处理框架的原理会多一些了解,知...
评分【本书适合的读者】 ①具有html/css/JavaScript基础,并不需要读者有太深的功底 ②对HTML5 Canvas画图功能感兴趣的 【本书可以帮你】 ①巩固你对原生JavaScript的理解,包括原型、对象、函数、事件等等。 ②养成良好的web前端编程习惯。因为本书的代码基本遵循了Douglas Crockf...

One of HTML5,s most exciting features, Canvas provides a powerful 2D graphics API that lets you implement everything from word processors to video games. In Core HTML5 Canvas, best-selling author David Geary presents a code-fueled, no-nonsense deep dive into that API, covering everything you need to know to implement rich and consistent web applications that run on a wide variety of operating systems and devices. Succinctly and clearly written, this book examines dozens of real-world uses of the Canvas API, such as interactively drawing and manipulating shapes, saving and restoring the drawing surface to temporarily draw shapes and text, and implementing text controls. You,ll see how to keep your applications responsive with web workers when you filter images, how to implement smooth animations, and how to create layered, 3D scrolling backgrounds with parallax. In addition, you,ll see how to implement video games with extensive coverage of sprites, physics, collision detection, and the implementation of a game engine and an industrial-strength pinball game. The book concludes by showing you how to implement Canvas-based controls that you can use in any HTML5 application and how to use Canvas on mobile devices, including iOS5. This authoritative Canvas reference covers * The canvas element-using it with other HTML elements, handling events, printing a canvas, and using offscreen canvases* Shapes-drawing, dragging, erasing, and editing lines, arcs, circles, curves, and polygons; using shadows, gradients, and patterns* Text-drawing, positioning, setting font properties; building text controls* Images-drawing, scaling, clipping, processing, and animating* Animations-creating smooth, efficient, and portable animations* Sprites-implementing animated objects that have painters and behaviors* Physics-modeling physical systems (falling bodies, pendulums, and projectiles), and implementing tweening for nonlinear motion and animation* Collision detection-advanced techniques, clearly explained* Game development-all aspects of game development, such as time-based motion and high score support, implemented in a game engine* Custom controls-infrastructure for implementing custom controls; implementing progress bars, sliders, and an image panner* Mobile applications-fitting Canvas apps on a mobile screen, using media queries, handling touch events, and specifying iOS5 artifacts, such as app icons Throughout the book, Geary discusses high-quality, reusable code to help professional developers learn everything they really need to know, with no unnecessary verbiage. All of the book,s code and live demonstrations of key techniques are available at corehtml5canvas.com.

评分二维绘图api讲解的详细且全面,基础交互功能的实现都有涉及,示例也很丰富。非常实用。
评分canvas讲解的很棒,当然需要html基础,要不会看不明白,代码编排相比较书中直接列一大串,旁边能有点注释可能会更好
评分Canvas的API都介绍得很详细,不过缺了点运动有关的算法
