Free gtk gimp software for linux

The GIMP is the GNU Image Manipulation Program. It is a freely distributed piece of software for such tasks as photo retouching, image composition and image authoring. The Gimp works on many operating systems, in many languages.
GIMP is an acronym for GNU Image Manipulation Program. It is a freely distributed program for such tasks as photo retouching, image composition and image authoring.
It has many capabilities. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc.
GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted.
GIMP is written and developed under X11 on UNIX platforms.
Main features:
Painting

GIMP# is an API wrapper around GIMP, written in C#. However, its not just a wrapper. GIMP# project also adds a thin layer which adds C# specific features, like iterating through a collection. An example of this is an iteration through the guides of an image. In C# this looks like:

foreach (Guide guide in image.Guides)
{
// Do something
}

In C this would have been:

gint32 guide_ID = 0:
while ((guide_ID = gimp_image_find_next_guide(image_ID, guide_ID)) != 0)
{
// Do something
}

GIMP# also offers a base plug-in class which does the difficult stuff for you. Implementing a new plug-in is just a matter of overriding a few virtual methods. See the samples directory for examples of how to do this.

Gimp# fills the niche between scripting languages (easy to write, slow) and C (harder to write, fast). If you need a quick and dirty plug-in where speed doesnt matter that much, write it in any of the scripting languages that come with GIMP (Scheme, Perl, etc.). Scripting languages are very well fitted for calling existing functionality, shortening manual tasks.

You probably dont want pixel manipulation in Scheme. In C, on the other hand, it takes a lot more time to create a plug-in for several reasons: building the GUI is time consuming. Secondly, pixel handling is not completely trivial. You have to know how to traverse through the tiles of an image, etc. Typically the actual algorithm is only a very small (5 - 20 %) part of the total code. Gimp# is not as fast as C, but much faster than a scripting language. Building a decent GUI is much easier than in C.

SLgtk package binds the GIMP Toolkit, also known as Gtk, to the S-Lang scripting language. This application was created with the SLIRP code generator, and provides an importable module which makes most of Gtk and its constituent libraries callable directly from S-Lang scripts.
With SLgtk the S-Lang programmer now has access to a powerful, cross-platform widget set for creating sophisticated graphical user interfaces (GUIs). The package also includes bindings to GtkExtra, which are used in the vwhere visualization and filtering guilet, as well as a gdk-pixbuf loader for the FITS image file format widely used within astronomy, and an easy-to-use but powerful image compositing, display, and output tool.
Enhancements:
VWhere 1.3.9:
- When a vector is passed with the & operator VWhere will reflect the proper variable name in the Axis Expression window, instead of assigning the less-meaningful "arrayN".
imdisplay 0.3.4:
- new "panes" option added, to support display of multiple images using either horizontal or vertical tiling
- multiple animations may now be displayed, and even commingled alongside static images
- fill rule may now be specified in an option string, and now defaults to "scale" instead of "none"
- imdisplay_defaults() function added, for option persistence
- 1D images which can be reshaped to NxN are now accepted
changed S-Lang semantics of C Gdk function void gdk_window_get_frame_extents(GdkWindow, &GdkRectangle) to GdkRectantle gdk_window_get_frame_extents(GdkWindow)
- more sophisticated placement/reparenting strategies for win chaining
- rgbwidget version 0.3.0, which adds POW scaling and version info

gimphp is a PHP Class library to write Gimp scripts directly in PHP.

To realize the Cultural Association Milug cards it was created a web-application that is based on PHP to use Gimp as a graphic engine. It work with gimuse server to produce cards.

The GTK-Qt Theme Engine is a project allowing GTK to use Qt widget styles.
Gtk-Qt Theme Engine behaves like a normal GTK theme engine, but calls functions from Qt instead of doing the drawing itself.
Version restrictions:
- Due to an incompatibility between Qt and the GNOME window manager, some parts of GNOME will not be themed by Qt.
- The theme will run fine under GNOME, but the logout box and window border menus will appear blank.
- It appears that the only way to overcome this bug is by patching Qt itself.

GTK+ Send-PR is a user friendly GNATS client.

gtk-send-pr is a problem report tool, designed to send reports to a GNATS database server using libesmtp to deliver mail.

The program has a user friendly interface and lets you use any SMTP server, including support for AUTH and TLS, to send the report, removing the need for a local configured sendmail. gtk-send-pr is part of both the FreeBSD ports and NetBSDs pkgsrc.

GTK-VNC project is a VNC viewer widget for GTK.

It provides a core library written in C, using coroutines to allow it to be completely asynchronous while remaining single threaded. A wrapper library using PyGTK provides access to the widget functionality from Python. Two example programs illustrate use of the widget by re-implementing the traditional vncviewer in a few 10s of lines of code.

The client is fully IPv6 aware, and as well as the traditional VNC authentication protocol, implements the VeNCrypt extension to provide secure TLS/SSL encrypted communications, optionally using x509 certificates to authenticate.
