How can i convert an integer ranging from 0 to 255 to a string with exactly two chars, containg the hexadecimal representation of the number?
Example
input: 180
output: “B4”
My goal is to set the grayscale color in Graphicsmagick. So, taking the same example i want the following final output:
“#B4B4B4”
so that i can use it for assigning the color: Color(“#B4B4B4”);
Should be easy, right?
