I have an doubt, I don't know how to use cmyk colors in android. If any one knows please help me. I am waiting for your valuable replies.
推荐答案
您只需要一个函数,该函数转换CMYK值RGB?或者,你想一个整体的形象,这是CMYK转换?
You just need a function, which converts the CMYK value to RGB? Or do you want to convert a whole image, which is CMYK?
对于第一个问题,伪code rgb2cmyk:
For the first problem, as pseudocode rgb2cmyk:
int r,g,b,c,m,y,k;
int computedC,computedM,computedY;
int minCMY;
if(r==0 && g==0 && b==0) return {0,0,0,1}
computedC = 1 - (r/255);
computedM = 1 - (g/255);
computedY = 1 - (b/255);
minCMY = Math.min(computedC,Math.min(computedM,computedY));
computedC = (computedC - minCMY) / (1 - minCMY) ;
computedM = (computedM - minCMY) / (1 - minCMY) ;
computedY = (computedY - minCMY) / (1 - minCMY) ;
return {computedC,computedM,computedY,minCMY};
和周围的其他方式,只是计算它向后:)
And for the other way around, just calculate it backwards :)
有关问题没有。 2:
它更容易,因为有一个叫ColorSpace的专用工具:
