ChTIFF 1.0 is the Ch binding to Tag Image File Format (TIFF) C library 
version 3.5.7.  ChTIFF enables all functions in the TIFF library for use 
in Ch.  With ChTIFF, these functions can run in Ch interpretively without 
compilation.  ChTIFF allows .tif images to be used in Ch.

Installation Instructions:
--------------------------
Assume <CHHOME> is the directory where Ch is installed,
for example if Ch is installed in C:/Ch, then C:/Ch should be used
instead of <CHHOME> for instructions below.
Assume <ChTIFF_HOME> is the directory where ChTIFF package is installed,
for example <ChTIFF_HOME> shall be substituted by C:/Ch/package/chtiff
(1) Move the directory ./chtiff to <CHHOME>/package/chtiff.
    <CHHOME>/package/chtiff becomes the home directory of <ChTIFF_HOME>
    Or
    If you do not want to move the directory, you should add a new path
    to the system variable _ppath for package path by adding
    the following statement in system startup file <CHHOME>/config/chrc
    or individual user's startup file ~/chrc.
     _ppath = stradd(_ppath, "<PARENT_DIR_OF_ChTIFF_HOME>;"); 
(2) Copy header files in tinclude/ to /toolkit/include directory.
    Or add the system variable _ipath in system startup file indicated
    in previous step by adding the following statement.
    _ipath = stradd(_ipath, "<ChTIFF_HOME>/include;");

    The above step (2) will not be necessary if the following code fragment
    is in application programs.
         #pragma package <chtiff>
(3) In the directory <ChTIFF_HOME>/dl there are three .dl files, one each for 
    Linux, Windows, and Solaris; rename the file corresponding to your 
    operating system to libtiff.dl.  For example, if you are running windows,
    rename "libtiff.dl_Windows" as "libtiff.dl".  Another option is to simply 
    run the script <ChTIFF_HOME>/src/createtiff.ch, which will automatically
    make the correct .dl file for your OS. 


Run Demo Programs in Directory demos:
-------------------------------------
(1) start ch
(2) run program name in demos dir.


Uninstallation Instructions:
----------------------------
(1) Remove ChTIFF_HOME directory
(2) Remove header files in <CHHOME>/toolkit/include
    copied from tinclude, if you have copied files
    tinclude to <CHHOME>/toolkit/include during installation.
