VIPS
|
|
====
|
|
|
|
VIPS 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 linuxes and OS X. There is a pre-compiled windows
|
|
binary on the vips website.
|
|
|
|
Getting VIPS from SVN
|
|
=====================
|
|
|
|
Enter:
|
|
|
|
svn co https://vips.svn.sourceforge.net/svnroot/vips/vips7
|
|
|
|
Building VIPS from source
|
|
=========================
|
|
|
|
In the VIPS directory, you should just be able to do:
|
|
|
|
user% ./configure
|
|
user% make
|
|
|
|
then as root:
|
|
|
|
root% make install
|
|
|
|
By default this will install files to /usr/local.
|
|
|
|
If you have problems, read on.
|
|
|
|
Building VIPS on win32
|
|
----------------------
|
|
|
|
Probably the easiest route is to use mingw/msys. This provides a GNU-style
|
|
build environment for win32.
|
|
|
|
http://www.vips.ecs.soton.ac.uk/index.php?title=Build_on_windows
|
|
|
|
Alternatively, vips-7.x/win32 contains sample build systems using the
|
|
Microsoft toolchain. See the README in there for details.
|
|
|
|
Building VIPS on OS X
|
|
---------------------
|
|
|
|
There are packages in macports.
|
|
|
|
http://www.macports.org
|
|
|
|
Dependencies
|
|
============
|
|
|
|
VIPS has to have glib-2.x and libxml-2.0. The build system needs perl,
|
|
pkg-config and gnu make.
|
|
|
|
Optional dependencies
|
|
---------------------
|
|
|
|
Optional support libraries ... also try ./configure --help to see flags for
|
|
controlling these libs. By default, if suitable versions are found, VIPS will
|
|
build support for them automatically.
|
|
|
|
VIPS looks for stuff in /usr. If you have installed your own versions of
|
|
these libraries to /usr/local, vips will not see them. Use switches to VIPS
|
|
configure like:
|
|
|
|
./configure --prefix=/home/john/vips \
|
|
--with-tiff-includes=/home/john/vips/include \
|
|
--with-tiff-libraries=/home/john/vips/lib
|
|
|
|
to get VIPS to see your builds.
|
|
|
|
libjpeg
|
|
The IJG JPEG library. We use 6b, but 6a works too.
|
|
|
|
libexif
|
|
if available, VIPS 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.
|
|
You'll need libz for this too. We use 1.1.3, others should work.
|
|
|
|
libz
|
|
If your TIFF library includes ZIP compression, you'll need this too.
|
|
|
|
videodev.h
|
|
If VIPS finds linux/videodev.h, you get support for Linux video
|
|
grabbing.
|
|
|
|
fftw3
|
|
If VIPS finds this library, it uses it for fourier transforms. It can
|
|
also use fftw2, but 3 is faster and more accurate.
|
|
|
|
If the library is not found, VIPS falls back to it's own internal FFT
|
|
routines which are slower and less accurate.
|
|
|
|
lcms
|
|
If present, im_icc_import(), _export() and _transform() are available
|
|
for transforming images with ICC profiles.
|
|
|
|
large files
|
|
VIPS 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, VIPS can load and save png files. Version 1.2+ preferred.
|
|
|
|
libMagick, or optionally GraphicsMagick
|
|
if available, VIPS adds support for loading all libMagick supported
|
|
image file types (about 80 different formats). No saving though.
|
|
|
|
pango
|
|
freetype2
|
|
fontconfig
|
|
if available, VIPS adds support for text rendering. You need the
|
|
package pangoft2 in "pkg-config --list-all"
|
|
|
|
liboil
|
|
if available, you get some inner loops replcaed by calls to liboil's
|
|
library of optimised inner loops
|
|
|
|
OpenEXR
|
|
if available, VIPS will directly read (but not write, sadly) OpenEXR
|
|
images
|
|
|
|
swig
|
|
python
|
|
python-dev
|
|
if available, we build the python binding too
