"HTML5 Canvas 2D API Specification Chinese Version"
Introduction
update time：2017-12-26Summary
This specification defines the two-dimensional Canvas (canvas) painting API, using these APIs allows
Immediate mode 2D graphics drawing on a Web page.
1 Introduction
This specification describes the API for immediate mode and for drawing 2D objects within a raster-style drawing area
A necessary method for vector graphics. Its main application is the canvas element defined by the HTML5 specification.
1.1 Terminology:
2D: Two-dimensional, you know
3D: Three dimensions, you know
API: programming interface
Canvas interface element: An element that implements the drawing methods and properties defined in this specification
Element, in short, is the "canvas" element
Drawing context: Drawing context, a Cartesian coordinate plane with the upper left corner (0,0),
In this plane, the x coordinate increases when going to the right and the y coordinate increases when going downward
Immediate-mode: Immediate mode, a drawing format, when the drawing is completed, all drawings
The structure will be discarded immediately from memory, and this API is the graphics drawing format
