This chapter contains step-by-step instructions on how to configure
|
|
and build the TIFF software distribution.
|
|
The software is most easily built on a UNIX system, but with a little
|
|
bit of work it can easily be built and used on other non-UNIX platforms.
|
|
|
|
<A NAME=UNIX><HR><H2>Building on a UNIX System</H2></A>
|
|
|
|
To build the software on a UNIX system
|
|
you need to first run the configure shell script
|
|
that is located in the top level of the source directory.
|
|
This script probes the target system for necessary tools and functions
|
|
and constructs a build environment in which the software may be
|
|
compiled.
|
|
Once configuration is done, you simply run <TT>make</TT>
|
|
to build the software
|
|
and then <TT>make install</TT> to do the installation; for example:
|
|
|
|
<UL><PRE>
|
|
hyla% <B>cd tiff-v3.4beta099</B>
|
|
hyla% <B>./configure</B>
|
|
<I>...lots of messages...</I>
|
|
hyla% <B>make</B>
|
|
<I>...lots of messages...</I>
|
|
hyla# <B>make install</B>
|
|
</PRE></UL>
|
|
|
|
In general, the software is designed such that the following should
|
|
be ``<I>make-able</I>'' in each directory:
|
|
|
|
<UL><PRE>
|
|
make [all] build stuff
|
|
make install build&install stuff
|
|
make clean remove .o files and cruft, but not executables
|
|
make clobber remove everything that can be recreated
|
|
make distclean remove <EM>absolutely everything</EM> that can be recreated
|
|
</PRE></UL>
|
|
|
|
Note that after running "<TT>make clobber</TT>" or
|
|
"<TT>make distclean</TT>" the <TT>configure</TT> script must
|
|
be run again to create the Makefiles and other make-related files.
|
|
|
|
<A NAME="BuildTrees"><P><HR WIDTH=65% ALIGN=right><H3>Build Trees</H3></A>
|
|
|
|
There are two schemes for configuring and building the software.
|
|
If you intend to build the software for only one target system, you
|
|
can configure the software so that it is built in the same directories
|
|
as the source code.
|
|
|
|
<UL><PRE>
|
|
hyla% <B>cd tiff-v3.4beta099</B>
|
|
hyla% <B>ls</B>
|
|
COPYRIGHT VERSION config.sub dist man
|
|
Makefile.in config.guess configure html port
|
|
README config.site contrib libtiff tools
|
|
hyla% <B>./configure</B>
|
|
</PRE></UL>
|
|
|
|
<P>
|
|
Otherwise, you can configure a build tree that
|
|
is parallel to the source tree hierarchy but which contains only
|
|
configured files and files created during the build procedure.
|
|
|
|
<UL><PRE>
|
|
hyla% <B>cd tiff-v3.4beta099</B>
|
|
hyla% <B>mkdir obj obj/mycpu</B>
|
|
hyla% <B>cd obj/mycpu</B>
|
|
hyla% <B>../../configure</B>
|
|
</PRE></UL>
|
|
|
|
This second scheme is useful for:
|
|
|
|
<UL>
|
|
<LI>building multiple targets from a single source tree
|
|
<LI>building from a read-only source tree (e.g. if you receive
|
|
the distribution on CD-ROM)
|
|
</UL>
|
|
|
|
<A NAME="ConfigFiles"><P><HR WIDTH=65% ALIGN=right><H3>Configuration Files</H3></A>
|
|
|
|
The configuration process is critical to the proper compilation,
|
|
installation, and operation of the software.
|
|
The configure script runs a series of tests to
|
|
decide whether or not the target system
|
|
supports required functionality and, if it does not, whether it
|
|
can emulate or workaround the missing functions.
|
|
This procedure is fairly complicated and, due to the nonstandard
|
|
nature of most UNIX systems, prone to error.
|
|
The first time that you configure the software for use you should
|
|
check the output from the configure script and look for anything
|
|
that does not make sense for your system.
|
|
A sample configure run is shown below together with an explanation
|
|
of some of the work that is done.
|
|
|
|
<P>
|
|
A second function of the configure script is to set the default
|
|
configuration parameters for the software.
|
|
Of particular note are the directories where the software is to be
|
|
installed.
|
|
By default the software is installed in the <B>/usr/local</B> hierarchy.
|
|
To change this behaviour the appropriate parameters can be
|
|
specified either:
|
|
<UL>
|
|
<LI>on the command line to configure,
|
|
<LI>in a site-wide configuration file, or
|
|
<LI>in a target-specific configuration file.
|
|
</UL>
|
|
configure reads any site-wide configure file first, and
|
|
then any target-specific configuration file.
|
|
This permits target-specific definitions to override
|
|
site-wide definitions.
|
|
|
|
<P>
|
|
Site-wide configuration files are named
|
|
<B>config.site</B> and are automatically searched for first
|
|
in any directory specified on the command line to configure
|
|
(using the <TT>-site</TT> option), or if that fails, in
|
|
the directory in in which the configure script is located.
|
|
|
|
<P>
|
|
Target-specific configuration files are named <B>config.local</B>
|
|
and are looked for first in the top-level configuration directory,
|
|
or, if that fails, in the directory in which the configure script
|
|
is located.
|
|
|
|
<P>
|
|
Configuration files are just shell scripts that define
|
|
shell variables that control the configuration process.
|
|
For example, the following file might be used on a BSDI system to
|
|
configure the software for installation in the <B>/usr/contrib</B> area.
|
|
|
|
<PRE>
|
|
#
|
|
# Parameters suitable for BSDI 1.1
|
|
#
|
|
DIR_BIN="/usr/contrib/bin" # directory for client apps
|
|
DIR_LIB="/usr/contrib/lib" # directory for libraries
|
|
DIR_MAN="/usr/contrib/man" # directory for manual pages
|
|
</PRE>
|
|
|
|
<P>
|
|
For a complete list of the possible configuration parameters look
|
|
at the sample <B>config.site</B> file provided in the distribution; the
|
|
section below describes some of the more important parameters.
|
|
|
|
<A NAME="Packages"><P><HR WIDTH=65% ALIGN=right><H3>Configuring Optional Packages/Support</H3></A>
|
|
|
|
The TIFF software comes with several packages that are installed only
|
|
as needed, or only if specifically configured at the time
|
|
the configure script is run. Packages can be configured in a
|
|
<B>config.site</B> or <B>config.local</B> file, or by using a
|
|
<TT>-with-<PACKAGE></TT> option when invoking configure;
|
|
e.g. <TT>configure -with-AFM</TT>.
|
|
|
|
<DL>
|
|
<DT><I>DSO Support</I>
|
|
<DD>The <TT>DSO</TT> support controls whether or not to
|
|
configure the software
|
|
to build a Dynamic Shared Object for the TIFF library.
|
|
Use of DSOs can significantly reduce the disk space needed for
|
|
users of the TIFF software.
|
|
If DSOs are not used then the code is statically linked into
|
|
each application that uses it.
|
|
By default this support is configured only if the system appears
|
|
to suport DSOs in a way that fits into the normal build scheme
|
|
(<TT>auto</TT>).
|
|
If DSO support is <EM>explicitly enabled</EM> and there is no
|
|
support for using DSOs in the expected way then DSOs are not used.
|
|
|
|
<P>
|
|
<DT><I>JPEG Support</I>
|
|
<DD>The <TT>JPEG</TT> package enables support for the handling
|
|
of TIFF images with JPEG-encoded data.
|
|
Support for JPEG-encoded data requires the Independent JPEG Group (IJG)
|
|
<TT>libjpeg</TT> distribution; this software is available at
|
|
<A HREF=ftp://ftp.uu.net/graphics/jpeg/>ftp.uu.net:/graphics/jpeg/</A>.
|
|
If JPEG support is enabled the <TT>DIRS_LIBINC</TT> and <TT>DIR_JPEGLIB</TT>
|
|
parameters should also be set (see below).
|
|
By default JPEG support is not configured.
|
|
|
|
<P>
|
|
<DT><I>ZIP Support</I>
|
|
<DD>The <TT>ZIP</TT> support enables support for the handling
|
|
of TIFF images with deflate-encoded data.
|
|
Support for deflate-encoded data requires the freely available
|
|
<TT>zlib</TT> distribution written by Jean-loup Gailly and Mark Adler;
|
|
this software is available at
|
|
<A HREF=ftp://ftp.uu.net/pub/archiving/zip/zlib/>ftp.uu.net:/pub/archiving/zip/zlib/</A>
|
|
(or try <A HREF=ftp://quest.jpl.nasa.gov/beta/zlib/>quest.jpl.nasa.gov:/beta/zlib/</A>).
|
|
If ZIP support is enabled the <TT>DIRS_LIBINC</TT> and <TT>DIR_GZLIB</TT>
|
|
parameters should also be set (see below).
|
|
By default this package is not configured.

Next various system-specific libraries that may or may not be needed

This file can take a long time to create so configure

generates the file only when it is needed, either because the

is to be used.
|

Note that running "<TT>make distclean</TT>" in the top-level directory

Certain library functions used by the tools are not present on all systems

configure checks for the presence of such functions and if they are
|
|
missing, will configure emulation code from the <B>port</B> directory

adding to the code to the <B>port</B> directory.

|
|
create a file <B>port/foo.c</B> that contains the emulation code

the configure script to automatically check for the missing function.

configure will verify the system and compiler are capable of

constructing SVR4-style DSO's in the expected way. Note that

while a system may support DSO's the compiler may not be

configure to prompt for a new value of the specified parameter.

Typing anything else causes configure to prompt for a new

In general hitting carriage return will accept the current

<A NAME=DSOSupport><P><HR><H3>Shared Library Support</H3></A>
|
|
|
|
It is desirable to make the TIFF library be a shared object
|
|
on systems that have support for shared libraries.
|
|
Unfortunately the rules to use to build a shared library
|
|
vary between operating systems and even compilers.
|
|
The distributed software includes support for building a shared
|
|
version of the library on a number of different systems.
|
|
This support is split between rules in the file
|
|
<B>libtiff/Makefile.in</B> that construct the shared library
|
|
and checks done by the <TT>configure</TT> script to verify that
|
|
the expected rules are supported by compilation tools for
|
|
the target system.
|
|
|
|
<P>
|
|
To add new support for building a shared library both these files
|
|
must be updated.
|
|
In the configure script search for the section where the autoconfiguration
|
|
setting of the <TT>DSO</TT> parameter is handled and
|
|
add a new case for the target system that sets the
|
|
<TT>DSOSUF</TT>,
|
|
<TT>DSOLD</TT>,
|
|
<TT>DSOOPTS</TT>,
|
|
and
|
|
<TT>LIBCOPTS</TT>
|
|
options as appropriate for the system.
|
|
<TT>DSOSUF</TT> specifies the filename suffix used for the shared
|
|
library (e.g. ``.so'' for Dynamic Shared Objects on most SVR4-based
|
|
systems).
|
|
<TT>DSOLD</TT> specifies the program to use to build the shared library
|
|
from a compiled object file; typically ``${LD}'' though on some systems
|
|
it is better to use the C compiler directly so system-dependent options and
|
|
libraries are automatically supplied.
|
|
<TT>DSOOPTS</TT> are options that must be specified to <TT>DSOLD</TT>
|
|
when building the shared library.
|
|
<TT>LIBCOPTS</TT> are options to pass to the C compiler when constructing
|
|
a relocatable object file to include in a shared library; e.g. ``-K PIC''
|
|
on a Sun system.
|
|
The <TT>DSO</TT> parameter must also be set to a unique label that identifies
|
|
the target system and compilation tools.
|
|
This label is used to select
|
|
a target in <B>libtiff/Makefile.in</B> to do the actual work in building
|
|
the shared library.
|
|
Finally, to complete support for the shared library added the appropriate
|
|
rules to <B>libtiff/Makefile.in</B> under the target specified in the
|
|
<TT>configure</TT> script.

|
|
|
With Microsoft Visual C++ installed, and properly configured for commandline
|
|
use (you will likely need to source VCVARS32.BAT in AUTOEXEC.bAT or somewhere
|
|
similar) you should be able to use the provided <tt>makefile.vc</tt>.<p>
|
|
|
|
<pre>
|
|
C:\LIBTIFF\LIBTIFF> nmake /f makefile.vc
|
|
C:\LIBTIFF\LIBTIFF> cd ..\tools
|
|
C:\LIBTIFF\TOOLS> nmake /f makefile.vc
|
|
</pre>
|
|
|
|
This will build the library file <tt>LIBTIFF\LIBTIFF\LIBTIFF.LIB</tt>. This
|
|
can be used in Win32 programs. If used in a project using the /MD compiler
|
|
switch (using the runtime C library), it may be necessary to modify the
|
|
CFLAGS macro in makefile.vc to correspond.<p>
|
|
|
|
The makefile also builds a DLL (libtiff.dll) with an associated import
|
|
library (libtiff_i.lib). Any builds using libtiff will need to include
|
|
the LIBTIFF\LIBTIFF directory in the include path.<p>
|
|
|
|
The <tt>libtiff\tools\makefile.vc</tt> should build .exe's for all the
|
|
standard TIFF tool programs.<p>
|
|
|
|
NOTE: The contents of the contrib/win32 directory should no longer be
|
|
needed, and are kept in the distribution temporarily.<p>

|
|
|
|
<P>
|
|
The directory <B>contrib/dosdjgpp</B>
|
|
contains the files necessary to build the library and tools
|
|
with the DJGPP v2 compiler under MSDOS.
|
|
|
|
<P>
|
|
All you have to do is copy the files in the directory
|
|
into the respective directories and run
|
|
make. If you want, you can use the <B>conf.bat</B> script
|
|
to do that for you, make sure that
|
|
the file is stored with MSDOS text EOL-convention (CR/LF), otherwise the
|
|
<B>command.com</B> will not do anything.
|
|
|
|
<P>
|
|
Note that you probably will not be able to build the library with the v1.x
|
|
versions of djgpp, due to two problems. First, the top makefile calls a
|
|
sub-make for each directory and you are likely to run out of memory, since
|
|
each recursive invocation of a djgpp v1.x program requires about 130k, to
|
|
avoid that, you can enter the directories manually and call make (well, there
|
|
are only two dirs). The 2nd problem is that djgpp 1.x doesn't call the
|
|
coff2exe (stubify) program when creating an executable. This means that all
|
|
programs compiled are not converted to exe and consequently are not available
|
|
for calling directly. For the tools directory, you can just call coff2exe for
|
|
each program after make finishes, but in the libtiff directory, a few programs
|
|
are created during the make process that have to be called for make to
|
|
continue (e.g. mkg3states). Make will probably report an error at each
|
|
such stage. To fix that, either add a coff2exe call before each program is
|
|
called or call coff2exe manually and rerun make (there 2-3 such programs).

<P>
|

This directory contains all of the utilities and makefile source
|
|
to build the LIBTIFF library and tools from the MPW Shell. The
|
|
file BUILD.mpw in this directory is an executable script
|
|
which uses all of these files to create the MPW makefiles and
|
|
run them.
|
|
|
|
<P>
|
|
The <file>.make files are not MPW makefiles as such,
|
|
but are when run through the "mactrans" program, which turns
|
|
the ascii "%nn" metacharacters into the standard weird MPW
|
|
make characters.
|
|
|
|
<P>
|
|
This translation trick is necessary to protect the files when
|
|
they are put into unix tarfiles, which tend to mangle the
|
|
special characters.

This release has been tested on OpenVMS/VAX 5.5-2, using VAX C 3.2.
|
|
A previous release was tested under OpenVMS/AXP ?.? using DEC C ?.?, it is
|
|
believed that this release as well works on AXP.
|
|
The code contains some GNU C specific things. This does *not* imply,
|

however, that the VAX/GCC configuration has been tested, *it has not*.
|

<P>

The command procedures (<TT>MAKEVMS.COM</TT>) for building the

automatically.
|
|
|
|
<P>
|
|
On the AXP, IEEE floating point is used by default. If you want VAX
|
|
floating point, remove the <TT>/FLOAT=IEEE_FLOAT</TT> qualifier, and change
|
|
<TT>HAVE_IEEEFP=1</TT> to <TT>HAVE_IEEEFP=0</TT> in the <TT>MAKEVMS.COM</TT>

<H3>Compiling your own program on a VMS system:</H3>

|
|
following command
|
|
<PRE>
|
|
$ CC/INCLUDE=DISK:[TIFF.LIBTIFF]
|
|
</PRE>
|
|
This ensures that the header file is found.

On the AXP, also add <TT>/FLOAT=IEEE_FLOAT</TT>

(if used when building the library).

<H3>Linking your own program to the TIFF library on a VMS system:</H3>

Method 1 uses the shortest link time and smallest <TT>.EXE</TT>
|
|
files, but it
|
|
requires that <TT>TIFFSHR</TT> is defined as above at link time and
|
|
<STRONG>at run time</STRONG>.
|
|
Using the compilation procedure above, the tools are linked in this way.
|
|
|
|
<P>
|
|
Method 2 gives somewhat longer link time and larger <TT>.EXE</TT>
|
|
files, but does
|
|
not require <TT>TIFFSHR</TT> to be defined. This method is recommended if you
|
|
want to run your program on another machine, and for some reason don't
|
|
want to have the library on that machine. If you plan to have more than
|
|
one program (including the tools) on the machine, it is recommended that
|
|
you copy the library to the other machine and use method 1.

|

The directory <B>contrib/acorn</B> contains support for compiling the library
|
|
under Acorn C/C++ under Acorn's RISC OS 3.10 or above. Subsequent pathnames
|
|
will use the Acorn format: The full-stop or period character is a pathname
|
|
delimeter, and the slash character is not interpreted; the reverse position
|
|
from Unix. Thus "libtiff/tif_acorn.c" becomes "libtiff.tif_acorn/c".
|
|

<P>
|
|
<H3>Installing LibTIFF:</H3>
|
|
|
|
<P>
|
|
LIBTIFF uses several files which have names longer than the normal RISC OS
|
|
maximum of ten characters. This complicates matters. Maybe one day Acorn will
|
|
address the problem and implement long filenames properly. Until then this
|
|
gets messy, especially as I'm trying to do this with obeyfiles and not have
|
|
to include binaries in this distribution.
|
|
|
|
<P>
|
|
First of all, ensure you have Truncate configured on (type <TT>*Configure
|
|
Truncate On</TT>)
|
|
|
|
<P>
|
|
Although it is, of course, preferable to have long filenames, LIBTIFF can be
|
|
installed with short filenames, and it will compile and link without
|
|
problems. However, <I>getting</I> it there is more problematic.
|
|
<B>contrib.acorn.install</B> is an installation obeyfile which will create a normal

Acorn-style library from the source (ie: with c, h and o folders etc.), but
|
|
needs the distribution library to have been unpacked into a location which is
|
|
capable of supporting long filenames, even if only temporarily.
|
|
|
|
<P>
|
|
My recommendation, until Acorn address this problem properly, is to use Jason
|
|
Tribbeck's <A
|
|
HREF=ftp://ftp.demon.co.uk/pub/mirrors/hensa/micros/arch/riscos/c/c020/longfiles.arc>LongFilenames</A>, or any other
|
|
working system that gives you long filenames, like a nearby NFS server for
|
|
instance.
|
|
|
|
<P>
|
|
If you are using Longfilenames, even if only temporarily to install LIBTIFF,
|
|
unpack the TAR into a RAMDisc which has been longfilenamed (ie: <TT>*addlongfs
|
|
ram</TT>) and then install from there to the hard disk. Unfortunately
|
|
Longfilenames seems a bit unhappy about copying a bunch of long-named files
|
|
across the same filing system, but is happy going between systems. You'll
|
|
need to create a ramdisk of about 2Mb.
|
|
|
|
<P>
|
|
Now you can run the installation script I've supplied (in contrib.acorn),
|
|
which will automate the process of installing LIBTIFF as an Acorn-style
|
|
library. The syntax is as follows:
|
|
|
|
<P><TT>
|
|
install <source_dir> <dest_dir>
|
|
|
|
</TT><P>
|
|
Install will then create <dest_dir> and put the library in there. For
|
|
example, having used LongFilenames on the RAMDisk and unpacked the library
|
|
into there, you can then type:
|
|
|
|
<P><TT>
|
|
Obey RAM::RamDisc0.$.contrib.acorn.install RAM::RamDisc0.$ ADFS::4.$.LIBTIFF
|
|
</TT><P>
|
|
|
|
It doesn't matter if the destination location can cope with long filenames or
|
|
not. The filenames will be truncated if necessary (*Configure Truncate On if
|
|
you get errors) and all will be well.
|
|

<H3>Compiling LibTIFF:</H3>
|
|
|

<P>
|
|
Once the LibTIFF folder has been created and the files put inside, making the
|
|
library should be just a matter of running '<B>SetVars</B>' to set the
|
|
appropriate system variables, then running '<B>Makefile</B>'.

<A HREF=ftp://ftp.acorn.co.uk/pub/riscos/releases/oslib/oslib.arc>OSLib</A>
|
|
is a comprehensive API for RISC OS machines, written by Jonathan Coxhead of
|
|
Acorn Computers (although OSLib is not an official Acorn product). Using the
|
|
OSLib SWI veneers produces code which is more compact and more efficient than
|
|
code written using _kernel_swi or _swi. The Acorn port of LibTIFF can take
|
|
advantage of this if present. Edit the Makefile and go to the Static
|
|
dependencies section. The first entry is:
|
|
|
|
<PRE>
|
|
# Static dependencies:
|
|
@.o.tif_acorn: @.c.tif_acorn
|
|
cc $(ccflags) -o @.o.tif_acorn @.c.tif_acorn
|
|
</PRE>
|
|
<P>
|
|
Change the cc line to:
|
|
<PRE>
|
|
cc $(ccflags) -DINCLUDE_OSLIB -o @.o.tif_acorn @.c.tif_acorn
|
|
</PRE>
|
|
<P>
|
|
Remember, however, that OSLib is only <I>recommended</I> for efficiency's
|
|
sake. It is not required.

|
|
|
|
This section contains information that might be useful
|
|
if you are working on a non-UNIX system that is not directly supported.
|
|
All library-related files described below are located in the <B>libtiff</B>
|
|
directory.
|
|
|
|
<P>
|
|
The library requires two files that are generated <I>on-the-fly</I>.
|
|
The file <B>tif_fax3sm.c</B> has the state tables for the
|
|
Group 3 and Group 4 decoders.
|
|
This file is generated by the <TT>mkg3states</TT> program
|
|
on a UNIX system; for example,
|
|
|
|
<UL><PRE><TT>
|
|
cd libtiff
|
|
cc -o mkg3states mkg3states.c
|
|
rm -f tif_fax3sm.c
|
|
./mkg3states -c const tif_fax3sm.c
|
|
</TT></PRE></UL>
|
|
|
|
The <TT>-c</TT> option can be used to control whether or not the
|
|
resutling tables are generated with a <TT>const</TT> declaration.
|
|
The <TT>-s</TT> option can be used to specify a C storage class
|
|
for the table declarations.
|
|
The <TT>-b</TT> option can be used to force data values to be
|
|
explicitly bracketed with ``{}'' (apparently needed for some
|
|
MS-Windows compilers); otherwise the structures are emitted in
|
|
as compact a format as possible.
|
|
Consult the source code for this program if you have questions.
|
|
|
|
<P>
|
|
The second file required to build the library, <B>version.h</B>,
|
|
contains the version
|
|
information returned by the <TT>TIFFGetVersion</TT> routine.
|
|
This file is built on most systems using the
|
|
<TT>mkversion</TT> program and the contents of the
|
|
<TT>VERSION</TT> and <TT>tiff.alpha</TT> files; for example,
|
|
|
|
<UL><PRE>
|
|
cd libtiff
|
|
cc -o mkversion mkversion.c
|
|
rm -f version.h
|
|
./mkversion -v ../VERSION -a ../dist/tiff.alpha version.h
|
|
</PRE></UL>
|
|
|
|
<P>
|
|
Otherwise, when building the library on a non-UNIX system be sure to
|
|
consult the files <B>tiffcomp.h</B> and <B>tiffconf.h</B>.
|
|
The former contains system compatibility definitions while the latter
|
|
is provided so that the software configuration can be controlled
|
|
on systems that do not support the make facility for building
|
|
the software.
|
|
|
|
<P>
|
|
Systems without a 32-bit compiler may not be able to handle some
|
|
of the codecs in the library; especially the Group 3 and 4 decoder.
|
|
If you encounter problems try disabling support for a particular
|
|
codec; consult the <A HREF=internals.html#Config>documentation</A>.
|
|
|
|
<P>
|
|
Programs in the tools directory are written to assume an ANSI C
|
|
compilation environment.
|
|
There may be a few POSIX'isms as well.
|
|
The code in the <B>port</B> directory is provided to emulate routines
|
|
that may be missing on some systems.
|
|
On UNIX systems the <TT>configure</TT> script automatically figures
|
|
out which routines are not present on a system and enables the use
|
|
of the equivalent emulation routines from the <B>port</B> directory.
|
|
It may be necessary to manually do this work on a non-UNIX system.
|
|
|
|
|
|
<A NAME=Testing><P><HR><H2>Checking out the Software</H2></A>
|
|
|
|
<P>
|
|
Assuming you have working versions of <TT>tiffgt</TT> and <TT>tiffsv</TT>,
|
|
you can just
|
|
use them to view any of the sample images available for testing
|
|
(see the <A HREF=images.html>section on obtaining the test images</A>).
|
|
Otherwise, you can do a cursory check of the library with
|
|
the <TT>tiffcp</TT> and <TT>tiffcmp</TT> programs. For example,
|
|
|
|
<UL><PRE>
|
|
tiffcp -lzw cramps.tif x.tif
|
|
tiffcmp cramps.tif x.tif
|
|
</PRE></UL>
|
|
|
|
<P>
|
|
(<TT>tiffcmp</TT> should be silent if the files compare correctly).
