Introduction Why an article on "colors"? It's the same question I asked myself before writing this series. The fact is, in .NET, there are only two color formats that can be used: the RGB color model and the HSB color model. Those two are encaps
This example demonstrates how to convert between a color value in RGB (three integer values in the range 0 to 255 representing red, green, and blue) and HSB (three floating point values in the range 0 to 1.0 representing hue, saturation, and brightne
以原型的方式,给string字符串类型添加方法,用于实现颜色值格式的转换:不习惯使用原型方法的,只要借鉴实现方法就好! 代码如下: var reg = /^#([0-9a-fA-f]{3}|[0-9a-fA-f]{6})$/; /*RGB颜色转换为16进制*/ String.prototype.colorHex = function(){ var that = this; if(/^(rgb|RGB)/.test(that)){ var aColor = that.replace(/(?:\(|
