借鉴在Javascript中的图像顶部 [英] Drawing on top of an image in Javascript

问题描述

我想要让用户在浏览器中的图像上绘制。换句话说，我需要的两个的位图图形与绘图功能，无论是矢量还是位图。

I want to let the user draw on an image in a browser. In other words, I need both bitmapped graphics and drawing capabilities, whether vector or bitmapped.

画布看起来不错，但不支持IE，虽然有ExCanvas，不知是否ExCanvas是在IE6中统一使用足够稳定通过8。

Canvas looks good, but is not supported by IE, and though there is ExCanvas, I wonder if ExCanvas is stable enough for consistent use in IE6 through 8.

或最重要的，有一个支持所有这一切开箱即用的开源图像/绘图库？我发现了两个十几基于Web的图像编​​辑器或绘图工具，但没有支持的要求。 （我想避免的Flash / Flex的/的Silverlight / JavaFX的。）

Or best of all, is there an open-source image/drawing library that supports all this out of the box? I found two dozen or so Web-based image editors or drawing tools, but none support the requirements. (And I'd like to avoid Flash/Flex/Silverlight/JavaFX.)

推荐答案

虽然你说你想避免它，我会建议的Flash。你可以很容易地使用Flash 6或7和这些有90％的采用率。我会感到惊讶，如果你能得到的支持JavaScript的水平。闪光灯是真正的一次编写，到处运行，这将减少你的开发时间。

Even though you said you'd like to avoid it I'd suggest Flash. You could easily use Flash 6 or 7 and these have a > 90% adoption rate. I'd be surprised if you could get that level of support with JavaScript. Flash is truly write once run anywhere, which will cut down on your development time.
