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.

Graphene provides graphic types and their relative API; it does not deal with windowing system surfaces, drawing, scene graphs, or input.

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.

gtksourceviewmm is a portable C++ library that extends the standard GTK+ framework for multiline text editing with support for configurable syntax highlighting, unlimited undo/redo, search and replace, a completion framework, printing and other features typical of a source code editor.

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

Pango is a library for laying out and rendering of text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed, though most of the work on Pango so far has been done in the context of the GTK+ widget toolkit. Pango forms the core of text and font handling for GTK+-2.x.

Guile-RSVG wraps the RSVG library for Guile, allowing you to render SVG images onto Cairo surfaces.

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

GtkSourceView is a text widget that extends the standard GTK+ text widget GtkTextView. It improves GtkTextView by implementing syntax highlighting and other features typical of a source code editor.

Layer Shell is a Wayland protocol for desktop shell components, such as panels, notifications and wallpapers. It can be used to anchor windows to a corner or edge of the output, or stretch them across the entire output. It supports all Layer Shell features including popups and popovers.

GtkDatabox is a widget for live display of large amounts of fluctuating numerical data. It enables data presentation (for example, on linear or logarithmic scales, as dots or lines, with markers/labels) as well as user interaction (e.g. measuring distances).

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

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.

Layer Shell is a Wayland protocol for desktop shell components, such as panels, notifications and wallpapers. It can be used to anchor windows to a corner or edge of the output, or stretch them across the entire output. It supports all Layer Shell features including popups and popovers.

This package contains the standard GTK+ 2.x theming engines including Clearlooks, Crux, High Contrast, Industrial, LighthouseBlue, Metal, Mist, Redmond95 and ThinIce.

GdkPixbuf is a library that loads image data in various formats and stores it as linear buffers in memory. The buffers can then be scaled, composited, modified, saved, or rendered.

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.

This package provides a GdkPixbuf module for loading XMP images.

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.

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.
