    tifftopnm

    I am having issues using tifftopnm
    Tifftopnm User Manual

    By issues I mean I would like to send in an image and get out another image but i just get gibberish to my screen

    the manual for this confuses me but if I use tifftopnm Lena.tiff in dos i get gibberish. Is that because I should be using this in a program just as a function call?

    It has been a long time since I have used C how would I write a program to use this and then write the image? is it just a binary write?

    Code:
    tifftopnm inputimage.tif > outputimage.pnm
    The man page clearly states that the data is written to stdout.
    Code:
    //try
    //{
    	if (a) do { f( b); } while(1);
    	else   do { f(!b); } while(1);
    //}

    Nope. It's a program; it is not part of a C library.

    GNU C Function and Macro Index -- glibc reference manual

    The gibberish is the file! You redirect the output from stdout to the filename that you want

    Using command redirection operators

    The -alphaout is if you want some other part, the alpha channel, to go to a PGM file

    No! It is the (dos) shell. tifftopnm is a program that outputs to stdout (the console). If you redirect (>) the output, the shell will put that output in a file.
