RGBA是一种用于描述颜色的格式。RGBA代表着红(Red)、绿(Green)、蓝(Blue)和透明度(Alpha)，每个属性的值范围在0-255之间。通过将这四个属性的值结合起来，可以定义出任何可能的颜色。与RGB相比，RGBA还可以定义颜色的透明度，这使得它在某些场合下更为实用。RGBA格式在计算机技术中具有广泛应用。例如，...

i figure the code "rgba" is the abbreviation for Red, Blue, Green, and something starts with "a". Is "a" stands for "area"? My guess is that when the graphic is 3D, the value of "a" could then specify which color is for which surface. Could someone help me understand this??
RGBAstands forRedGreenBlueAlpha. While it is sometimes described as a color space, it is actually simply a use of the RGB color model, with extra information. The color isRGB, and may belong to any RGB color space, but an integral alpha value as invented byCatmullandSmithbetween1971and1972...
RGBA的意思是(Red-Green-Blue-Alpha)它是在RGB上扩展包括了“alpha”通道,运行对颜色值设置透明度。在RGBA中,四个数字以逗号分隔开,前面三个数字标识这个颜色的RGB值,这个设置和RGB并没有任何区别,RGBA也可以设置为百分比,后面的数字代表透明度,范围在0-1之间。1表示不透明,0表示全透明。前三个值(红绿蓝)的范围...
