How can I parse RGB color in web color format (3 or 6 hex digits) to
image/color? Does go have any built-in parser for that?I want to be able to parse both
#XXX colors formats.
color docs says nothing about it: https://golang.org/pkg/image/color/but this task is very common, so I believe that go has some functions for that (which I just didn't find).
I'm trying to convert "Hello" to
48 65 6c 6c 6f in hexadecimal as efficiently as possible using the command line.
I've tried looking at
printf and google, but I can't get anywhere.
Any help greatly appreciated.
Many thanks in advance,
Hi I have to convert std::string into
std::vector<unsigned char>. Let's assume string which contains 14 characters: 020000040800F2 and vector
v should contains 7 values. In the real program string will be a little bit longer.
std::vector<unsigned char> v(7);v = 2; // 02v = 0; // 00v = 0; // 00v = 4; // 04v = 8; // 08v = 0; // 00v = 242; //F2
I am writing in C++17. I was looking for known solutions in algorithm but there are not which could help me.Thank you so much guys for your help.
I have a hex string :
81 61 08 0a a0 80 04
now I want to reverse it like :
04 80 a0 0a 08 61 81
I have tried converting hex to number and then reversing it and convert back to hex but it doesn't provide the required result.
My application has a limit input of 16 hex characters to represent 8 ASCII characters. The only characters I need are A-Z and 0-9. I do not need lower cases or any non-standard alphanumeric characters. A 2 character hex can represent all of the characters on the keyboard, but I don't need all of it.
Is there some type of library that can compress the alphanumeric string to be able to fit it in 16 hex characters?
12345678 = 31 32 33 34 35 36 37 38
I want to be able to pack in more alphanumeric characters like this:
ABCDEFGHI12345678 = 31 32 33 34 35 36 37 38
Is there a library that does this?
