Cairo provides Perl bindings for the vector graphics library cairo. It supports multiple output targets, including PNG, PDF and SVG. Cairo produces identical output on all those targets.

Includes guile-clutter, guile-gnome-gstreamer, guile-gnome-platform (GNOME developer libraries), and guile-gtksourceview.

Webp-pixbuf-loader is a WebP format loader of GdkPixbuf.

Guile-Present defines a declarative vocabulary for presentations, together with tools to render presentation documents as SVG or PDF. Guile-Present can be used to make presentations programmatically, but also includes a tools to generate PDF presentations out of Org mode and Texinfo documents.

GTKmm is the official C++ interface for the popular GUI library GTK+. Highlights include typesafe callbacks, and a comprehensive set of widgets that are easily extensible via inheritance. You can create user interfaces either in code or with the Glade User Interface designer, using libglademm. There's extensive documentation, including API reference and a tutorial.

Cairo is a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System (via both Xlib and XCB), Quartz, Win32, image buffers, PostScript, PDF, and SVG file output. Experimental backends include OpenGL, BeOS, OS/2, and DirectFB.

LibThai is a set of Thai language support routines aimed to ease developers’ tasks to incorporate Thai language support in their applications.

Perl bindings to the 2.x series of the Gtk+ widget set. This module allows you to write graphical user interfaces in a Perlish and object-oriented way, freeing you from the casting and memory management in C, yet remaining very close in spirit to original API.

GtkDoc is a tool used to extract API documentation from C-code like Doxygen, but handles documentation of GObject (including signals and properties) that makes it very suitable for GTK+ apps and libraries. It uses docbook for intermediate files and can produce html by default and pdf/man-pages with some extra work.

Pango is a library for laying out and rendering text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed, but using Pango in conjunction with Cairo and/or Gtk2 provides a complete solution with high quality text handling and graphics rendering.

Dynamically loaded modules handle text layout for particular combinations of script and font backend. Pango provides a wide selection of modules, including modules for Hebrew, Arabic, Hangul, Thai, and a number of Indic scripts. Virtually all of the world's major scripts are supported.

In addition to the low level layout rendering routines, Pango includes Pango::Layout, a high level driver for laying out entire blocks of text, and routines to assist in editing internationalized text.

ATKmm is the C++ binding for the ATK library.

Perl bindings to the 3.x series of the gtk+ toolkit. This module allows you to write graphical user interfaces in a Perlish and object-oriented way, freeing you from the casting and memory management in C, yet remaining very close in spirit to original API.

This package provides a GdkPixbuf module for loading XMP images.

Guile-Cairo wraps the Cairo graphics library for Guile Scheme. Guile-Cairo is complete, wrapping almost all of the Cairo API. It is API stable, providing a firm base on which to do graphics work. Finally, and importantly, it is pleasant to use. You get a powerful and well-maintained graphics library with all of the benefits of Scheme: memory management, exceptions, macros, and a dynamic programming environment.

Pangomm provides a C++ programming interface to the Pango text rendering library.

Cairomm provides a C++ programming interface to the Cairo 2D graphics library.

GTK+, or the GIMP Toolkit, is a multi-platform toolkit for creating graphical user interfaces. Offering a complete set of widgets, GTK+ is suitable for projects ranging from small one-off tools to complete application suites.

Guile-XCB implements the XCB protocol and provides all the tools necessary to write X client code in Guile Scheme without any external dependencies.

Guile-WM is a simple window manager that's completely customizable—you have total control of what it does by choosing which modules to include. Included with it are a few modules that provide basic TinyWM-like window management, some window record-keeping, multi-monitor support, and emacs-like keymaps and minibuffer. At this point, it's just enough to get you started.

Hall is a command-line application and a set of Guile libraries that allow you to quickly create and publish Guile projects. It allows you to transparently support the GNU build system, manage a project hierarchy & provides tight coupling to Guix.

Guile-Udev provides GNU Guile bindings to libudev.

Guile-colorized provides you with a colorized REPL for GNU Guile.

This package provides a simple yaml module for Guile using the ffi-helper from nyacc.

Guile Knots is a collection of patterns and functionality that is useful when using Guile Fibers. This includes higher level concurrency utilities, support for timeouts and an alternative web server implementation.
