libvips
|
|
=======
|
|
|
|
libvips is an image processing library. It's good for large images and for
|
|
colour. There's a GUI as well, see the VIPS website:
|
|
|
|
http://www.vips.ecs.soton.ac.uk
|
|
|
|
There are packages for most unix-like operating systems, and binaries for
|
|
Windows and OS X.
|
|
|
|
Building libvips from source
|
|
============================
|
|
|
|
In the libvips directory, you should just be able to do:
|
|
|
|
$ ./configure
|
|
$ make
|
|
$ sudo make install
|
|
|
|
By default this will install files to /usr/local.
|
|
|
|
If you have problems, read on.
|
|

Building libvips on OS X

Building libvips from GIT
|
|
-------------------------
|
|
|
|
Checkout the latest sources with:
|
|
|
|
git clone git://github.com/jcupitt/libvips.git
|
|
|
|
Then for a debug build:
|
|
|
|
$ ./bootstrap.sh
|
|
$ CFLAGS="-g -Wall" CXXFLAGS="-g -Wall" ./configure --prefix=/home/john/vips --enable-gtk-doc
|
|
$ make
|
|
$ make install
|
|
|
|
Dependencies
|
|
============
|
|
|
|
libvips has to have gettext, glib-2.x and libxml-2.0. The build system needs
|
|
pkg-config and gnu make.
|
|
|
|
Optional dependencies
|
|
---------------------
|
|
|
|
If suitable versions are found, libvips will add support for these
|
|
libraries automatically. See "./configure --help" for a set of flags to
|
|
control library detection. Packages are generally found with pkg-config,
|
|
so make sure that is working.
|
|
|
|
libtiff and libjpeg do not usually use pkg-config so libvips looks for
|
|
them in the default path and in $prefix. If you have installed your own
|
|
versions of these libraries in a different location, libvips will not see
|
|
them. Use switches to libvips configure like:
|
|
|
|
./configure --prefix=/Users/john/vips \
|
|
--with-tiff-includes=/opt/local/include \
|
|
--with-tiff-libraries=/opt/local/lib \
|
|
--with-jpeg-includes=/opt/local/include \
|
|
--with-jpeg-libraries=/opt/local/lib
|
|
|
|
or perhaps:
|
|
|
|
CFLAGS="-g -Wall -I/opt/local/include -L/opt/local/lib" \
|
|
CXXFLAGS="-g -Wall -I/opt/local/include -L/opt/local/lib" \
|
|
./configure --without-python --prefix=/Users/john/vips
|
|
|
|
to get libvips to see your builds.
|
|
|
|
libjpeg
|
|
The IJG JPEG library.
|
|
|
|
libexif
|
|
if available, libvips adds support for EXIF metadata in JPEG files
|
|
|
|
libtiff
|
|
The TIFF library. It needs to be built with support for JPEG and
|
|
ZIP compression. 3.4b037 and later are known to be OK.
|
|
|
|
libz
|
|
If your TIFF library includes ZIP compression, you'll need this too.
|
|
|
|
videodev.h
|
|
If libvips finds linux/videodev.h, you get support for Linux video
|
|
grabbing.
|
|
|
|
fftw3
|
|
If libvips finds this library, it uses it for fourier transforms. It
|
|
can also use fftw2, but 3 is faster and more accurate.
|
|
|
|
lcms2
|
|
lcms
|
|
If present, im_icc_import(), _export() and _transform() are available
|
|
for transforming images with ICC profiles. If lcms2 is available,
|
|
it is used in preference to lcms.
|
|
|
|
large files
|
|
libvips uses the standard autoconf tests to work out how to support
|
|
large files (>2GB) on your system. Any reasonably recent *nix should
|
|
be OK.
|
|
|
|
libpng
|
|
if present, libvips can load and save png files.
|
|
|
|
libMagick, or optionally GraphicsMagick
|
|
if available, libvips adds support for loading all libMagick supported
|
|
image file types (about 80 different formats). Use
|
|
--with-magickpackage to build against graphicsmagick instead.
|
|
|
|
pangoft2
|
|
if available, libvips adds support for text rendering. You need the
|
|
package pangoft2 in "pkg-config --list-all"
|
|
|
|
orc-0.4
|
|
if available, vips will accelerate some operations with this run-time
|
|
compiler
|
|
|
|
matio
|
|
if available, vips can load images from Matlab save files
|
|
|
|
cfitsio
|
|
if available, vips can load FITS images
|
|
|
|
OpenEXR
|
|
if available, libvips will directly read (but not write, sadly)
|
|
OpenEXR images
|
|
|
|
OpenSlide
|
|
if available, libvips can load OpenSlide-supported virtual slide
|
|
files: Aperio, Hamamatsu VMS and VMU, MIRAX, and Trestle
|
|
|
|
swig
|
|
python
|
|
python-dev
|
|
if available, we build the python binding too
