Read pixel from text file

[fredteng]

Hi, is it possible to retrieve an image just by reading some parameters or its pixel from a text file? If yes, could anyone give me some ideas on how to do that? How do you also retrieve a specific line or value from a text file?

Thanks.

You are confusing two different concepts here.

Pixels have nothing to do with text files.

Pixels imply images which are some sort of binary file.

Text files have characters.  There is a Read Text File function on the File I/O palette.  You can right click on that to change the settings to be able to read bytes or read lines.

For examle if I want to read line 13 of my text file, I right click on Read Text File and click on Read Lines but what must by count be so that it reads line 13 of my text file?

Hi Fred,

it seems you started a new thread for that very same topic - again...

Why can't you keep things in one place? Why do we have to hop between several threads of yours to get all relevant information?

"if I want to read line 13 of my text file"

Same question as in the other thread: Where do you start to count? 0 or 1?

Have you tried to wire a "13" to the ReadLine function?
