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

GdkPixbuf-Xlib contains the deprecated API for integrating GdkPixbuf with Xlib data types. This library was originally shipped by gdk-pixbuf, and has since been moved out of the original repository. No newly written code should ever use this library.

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.

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.

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

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.

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.

This program allows you to display GTK+ dialog boxes from command line or shell scripts. Example of how to use yad can be consulted at https://sourceforge.net/p/yad-dialog/wiki/browse_pages/.

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.

Dragon is a lightweight drag-and-drop source for X where you can run:

dragon file.tar.gz

to get a window with just that file in it, ready to be dragged where you need it. What if you need to drag into something? Using:

dragon --target

you get a window you can drag files and text into. Dropped items are printed to standard output.

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.

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.

HarfBuzz is an OpenType text shaping engine.

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

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.

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.

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.

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.

GTK 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.

Libpanel provides a library to create IDE-like applications using GTK and libadwaita. It has widgets for panels, docks, columns and grids of pages. Primarily, its design and implementation focus around the GNOME Builder and Drafting projects.

GtkSpell provides word-processor-style highlighting and replacement of misspelled words in a GtkTextView widget.

The Assistive Technology Service Provider Interface, core components, is part of the GNOME accessibility project.

Libdatrie is an implementation of double-array structure for representing trie. Trie is a kind of digital search tree.
