Color class

Usage Example:

var color = new dojo.graphics.color.Color(dojo.graphics.color.named.black); //定义一个黑色的颜色对象
var color = new dojo.graphics.color.Color(0,0,0); //定义一个黑色的颜色对象
var color = new dojo.graphics.color.Color(0,0,0,1.0); //定义一个黑色的颜色对象
var color = new dojo.graphics.color.Color([0,0,0,1.0]); //定义一个黑色的颜色对象
var color = new dojo.graphics.color.Color('rgb(0,0,0)'); //定义一个黑色的颜色对象
var color = new dojo.graphics.color.Color('#000000'); //定义一个黑色的颜色对象
dojo.graphics.color.Color.toRgb

Usage Example:

color.toRgb();　//返回一个[0,0,0]的数组
color.toRgb(true);//返回一个[0,0,0,1.0]的数组
dojo.graphics.color.Color.toRgba

Usage Example:

color.toRgba();　//返回一个[0,0,0,1.0]的数组
dojo.graphics.color.Color.toHex
dojo.graphics.color.Color.toString

Usage Example:

Color.tohex (); Return to "#000000"

Color.tostring ()//Return to "#000000"

Dojo.graphics.color.Color.toCss

Usage Example:

Color.tocss (); Back to "RGB (0,0,0)"

Dojo.graphics.color.Color.blend

Mix another color to get a new color

Usage Example:

color.blend('#ffffff', 1);//返回[255,255,255]
color.blend('#ffffff', -1);//返回[0,0,0]
color.blend('#ffffff', 0);//按1比1混合黑色和白色，返回[127,127,127]
颜色参数可以为颜色的任意形式，比如数组，字符串等
or
dojo.graphics.color.blend([0,0,0], [255,255,255], 0);//will return [127,127,127]
dojo.graphics.color.blend("#000000", "#ffffff", 0);//will return "#7f7f7f"

If the first argument is a string, the return value also returns a string

Dojo.graphics.color.Color.blendHex

Usage Example:

Dojo.graphics.color.blendHex ("#000000", "#ffffff", 0);//will return "#7f7f7f"

Dojo.graphics.color.extractRGB

Converts input to an RGB array

Dojo.graphics.color.hex2rgb

Converts the input string to an RGB array

Dojo.graphics.color.rgb2hex

Converts the input RGB array to a string

Dojo.graphics.color.Color.fromArray

Usage Example:

var color = Dojo.graphics.color.Color.fromArray ([0,0,0,1.0]);

Module: Dojo.uri.Uri

Dojo.uri.Uri

Classes specifically used to process URIs (Uniform Resource Identifiers)

Usage Example:

uri = (new dojo.uri.Uri("http://myserver/dojo/", "guide.html")).toString();//uri will be "http://myserver/dojo/guide.html"
uri = (new dojo.uri.Uri("http://myserver/dojo/", "../guide.html")).toString();//uri will be "http://myserver/guide.html"

RFC-defined URI syntax: [scheme:][//authority][path][?query][#fragment]

Authority syntax: [user-info@]host[:p ORT]

For example, we define a URI

var uri = new Dojo.uri.Uri ("http://user:password@myserver:80/dojo/", "guide.html?page=1#top");

The properties of the URI are as follows:

Authority: Server name "USER:PASSWORD@MYSERVER:80"

Fragment: Fragment name "Top"

Host: hostname "MyServer"

Password: password "password"

Path: Paths "/dojo/guide.html"

Port: Ports 80

Query: Parameter "page=1"

Scheme: Mode "http"

URI: Full Address "http://user:password@myserver:80/dojo/guide.html?page=1"

User: The username, "User:" seems to have a problem with one more colon.
