Hello,
Here is a one liner solution:
HEX=[
"FF"
"D9"
"CC80FF"
"C2FF00"
"FFB5B5"
"909090"
"3050F8"
"FF0D0D"
"90E050"
"B3E3F5"
]
--> matrix(hex2dec(strsplit(strcat(HEX),2:2:length(strcat(HEX))-1)),3,-1)'
ans =
255. 255. 255.
217. 255. 255.
204. 128. 255.
194. 255.
Hello
Thanks for the suggestions. The 'part' option worked but the function fails at
hexrgb=strsplit(x(i),[2 4])';
strsplit: Wrong size for input argument #1: A single string expected.
This was the issue I was having initially, logically it should work, but looks
like it just sees x as a
Quick update. Following Serge, I managed to get from the HEX code to RGB via
the following, avoiding the issue of the submatrix incorrectly defined.
rgb=[part(Hex_colour,1:2),part(Hex_colour,3:4),part(Hex_colour,5:6)];
for i = 1:size(rgb,1)
red(i)=hex2dec(rgb(i,1));
green(i)=hex2dec(rgb(i,2));
Hello,
A basic solution would be to use part (several times) instead of strsplit:
function rgb=hex2rgb2(x)
// Assuming HEX is a column vector
hexrgb = [part(HEX, 1:2), part(HEX, 3:4), part(HEX, 5:6)];
rgb = hex2dec(hexrgb);
endfunction
