Convert 8-digit hex colors to rgba colors?

Question

Everything I\'ve found on this subject simply converts the hex to rgb and then adds an alpha of 1. I want to get the intended alpha from the hex digits as well.

A c

Answer 1

Here is a little tooltip for you :

In this case #DCDCDC8F the DC is alpha = 220,

Hex to Decimal [ DC ]:

1. first place D = 13 * 16^1 = 208
2. second place C = 12 * 16^0 = 12
3. sum = 12 + 208 = 220

then 220 / 255 = 0.86 opacity.

The bytes are stored in memory on a little-endian machine in the order AABBGGRR
