Delphi颜色的表示（一共5种表示法）

Posted 2020-06-23 朝闻道

//全以红色举例：

//1. RGB 模式：
Self.Color := $0000ff; 
//不过和html、PhotoShop、FireWorks中的 #ff0000 是完全反的，应该叫 BGR。

---

//2. RGB 分值，譬如：
Self.Color := RGB(255,0,0);

---

//3. Delphi 中的标准模式：
Self.Color := $000000ff;
//其中低3位字节代表RGB(BGR)相应的颜色；
//如果最高位字节是$00,则表示用系统调色板中最相近的颜色；
//最高位字节是$01，则表示用当前调色板中最相近的颜色匹配；
//最高位字节是$02，则用当前设备描述表中逻辑调色板的次相近颜色匹配。

---

//4. 整数：
Self.Color := 255;
//十六进制转换来的整数。

---

//5. 颜色常量：
Self.Color := clRed;
//Delphi 预定义的常量有：
