how to give color to an output text

Asked by Elysi Cochin on 8 Apr 2013

i saved my output in txt file.....

 myOutput = Image Processing is interesting

i wanted to display the word "Process" in green color and the remaining words in black color itself....

i found a link in which we can format the text in different ways....

but in all those examples we give the full text to change color... but i want only a portion of the text to change its color...

if found the starting position of Process and the position upto which i want to change color... but i dont know how to keep the other text colors black and "Process" only green...... please can someone help me solve it.... i need the output to be displayed either in command window or txt file.... but the only thing is the change in color shud be there.....please do reply....

Use a combination of FPRINTF and CPRINTF, without outputting CR/LF before the "final" end of line.

 >> fprintf('This is a ') ; cprintf('_red', 'colorful ') ; fprintf('example!\n') ;

but be aware that CPRINTF is rather slow.

 >> tic ; for k = 1:1e2, fprintf('.') ; end ; fprintf('\n') ; toc
 ....................... ..
 Elapsed time is 0.001758 seconds.
 >> tic ; for k = 1:1e2, cprintf('_red', '.') ; end ; fprintf('\n') ; toc
 ....................... ..
 Elapsed time is 1.458687 seconds.

I know this isn't what you want, but in case others want to know how to "burn" colored text into images, see this link :
