Introduction to Glitz

Glitz is an OpenGL image compositing library. Glitz provides Porter/Duff compositing of images and implicit mask generation for geometric primitives including trapezoids, triangles, and rectangles.

The semantics of Glitz are designed to precisely match the specification of the X Render extension. Glitz not only implements X Render features like component alpha and image transformations, but it also implement support for additional features like convolution filters and color gradients, which are not currently part of the X Render specification.

The performance and capabilities of Glitz are very dependent on your graphics hardware. Glitz does not in any way handle software fall-backs when the graphics hardware is insufficient. However, Glitz will report if any requested operation cannot be carried out by the graphics hardware, thus making a higher level software layer responsible for appropriate actions.

Glitz can be used as a stand-alone layer above OpenGL but is also designed to act as a backend for Cairo, providing it with OpenGL accelerated output.

Configuration Information

To use AGL, EGL, or WGL backends add the appropriate option for configure.

--enable-agl
--enable-egl
--enable-wgl

Non-Multilib

Note

If you have installed the X Window System into a location other than /usr, you will need to add the --x-includes=${XORG_PREFIX}/include and --x-libraries=${XORG_PREFIX}/lib options to configure.

Compile the package:

./configure --prefix=/usr &&
make

Install the package:

make install

Multilib

32Bit

Note

If you have installed the X Window System into a location other than /usr, you will need to add the --x-includes=${XORG_PREFIX}/include and --x-libraries=${XORG_PREFIX}/lib options to configure.

Compile the package:

CC="gcc ${BUILD32}" CXX="g++ ${BUILD32}" \
PKG_CONFIG_PATH="$PKG_CONFIG_PATH32" USE_ARCH=32 \
./configure --prefix=/usr &&
make

Install the package:

make install

N32

Note

If you have installed the X Window System into a location other than /usr, you will need to add the --x-includes=${XORG_PREFIX}/include and --x-libraries=${XORG_PREFIX}/lib32 options to configure.

Compile the package:

CC="gcc ${BUILDN32}" CXX="g++ ${BUILDN32}" \
PKG_CONFIG_PATH="$PKG_CONFIG_PATHN32" USE_ARCH=n32 \
./configure --prefix=/usr --libdir=/usr/lib32 &&
make

Install the package:

make install

Note

If you have installed the X Window System into a location other than /usr, you will need to add the --x-includes=${XORG_PREFIX}/include and --x-libraries=${XORG_PREFIX}/lib64 options to configure.

Compile the package:

CC="gcc ${BUILD64}" CXX="g++ ${BUILD64}" \
PKG_CONFIG_PATH="$PKG_CONFIG_PATH64" USE_ARCH=64 \
./configure --prefix=/usr --libdir=/usr/lib64 &&
make

Install the package:

make install
