Introduction to libtiff

The libtiff package contains the tiff libraries and associated utilities. The libraries are used by many programs for reading and writing tiff files and the utilities are useful for general work with tiff files.

libtiff dependencies

Optional

libjpeg-6b

Installation of libtiff

Install libtiff by running the following commands: 

./configure --prefix=/usr --noninteractive \
    --with-DIR_MAN=/usr/share/man \
    --with-ZIP=yes --with-DIR_GZLIB=/usr/lib &&
make &&
make install
[Note]

Note

configure prints false error messages that it is unable to find the library directories for ZIP (and JPEG) support. Ignore them. To verify that libtiff is indeed linked to these libraries, use the ldd command.

Command explanations

--noninteractive: This switch is used to avoid the configuration routine asking for confirmation of the installation directories (which we pass to configure).

--with-DIR_MAN=/usr/share/man: This is used because despite the fact we pass --prefix=/usr, the configure routine tries to install the man pages in /usr/local/man instead of the correct place.

--with-ZIP=yes --with-DIR_GZLIB=/usr/lib: This enables support for the handling of TIFF images with deflate-encoded data.

--with-JPEG=yes --with-DIR_JPEGLIB=/usr/lib: Use these switches to enable support for the handling of TIFF images with JPEG-encoded data.

Configuring libtiff

Configuration Information

As with most libraries, there is no configuration to do, save that the library directory i.e., /opt/lib or /usr/local/lib should appear in /etc/ld.so.conf so that ldd can find the shared libraries. After checking that this is the case, /sbin/ldconfig should be run while logged in as root.

Contents

fac2ps converts a TIFF facsimile to compressed PostScript file.

fax2tiff

fax2tiff creates a TIFF Class F fax file from raw fax data.

gif2tiff

gif2tiff creates a TIFF file from a GIF87 format image file.

pal2rgb

pal2rgb converts a palette color TIFF image to a full color image.

ppm2tiff

ppm2tiff creates a TIFF file from a PPM image file.

ras2tiff

ras2tiff creates a TIFF file from a Sun rasterfile.

raw2tiff

raw2tiff converts a raw byte sequence into TIFF.

rgb2ycbcr

rgb2ycbcr converts non-YCbCr TIFF images to a YCbCr TIFF image.

thumbnail

thumbnail creates a TIFF file with thumbnail images.

tiff2bw

tiff2bw converts a color TIFF image to grayscale.

tiff2pdf

tiff2pdf converts a TIFF image to a PDF document.

tiff2ps

tiff2ps converts a TIFF image to a PostScript file.

tiff2rgba

tiff2rgba converts a wide variety of TIFF images into an RGBA TIFF image.

tiffcmp

tiffcmp compares two TIFF files.

tiffcp

tiffcp copies (and possibly converts) a TIFF file.

tiffdither

tiffdither converts a grayscale image to bilevel using dithering.

tiffdump

tiffdump prints verbatim information about TIFF files.

tiffinfo

tiffinfo prints information about TIFF files.

tiffmedian

tiffmedian applies the median cut algorithm to data in a TIFF file.

tiffsplit

tiffsplit splits a multi-image TIFF into single-image TIFF files.

tiff libraries

The tiff libraries are used by many programs to read and write tiff files.
