Debian Edu Graphics packages

Dia is an editor for diagrams, graphs, charts etc. There is support for UML static structure diagrams (class diagrams), Entity-Relationship diagrams, network diagrams and much more. Diagrams can be exported to postscript and many other formats.

A package to reorganize menu branches in order to get a structure easy to use for teachers and students.

GIMP is an advanced picture editor. You can use it to edit, enhance, and retouch photos and scans, create drawings, and make your own images. It has a large collection of professional-level editing tools and filters, similar to the ones you might find in Photoshop. Numerous fine-control settings and features like layers, paths, masks, and scripting give you total control over your images.

Many image file formats are supported, including JPEG, Photoshop (.psd), and Paint Shop Pro (.psp) files. It can also be used to scan and print photos.

To open files remotely (like over HTTP), install the gvfs-backends package.

To use a MIDI device (like a musical keyboard) as an input controller in GIMP, install libasound2 and read the how-to at /usr/share/doc/gimp/README.MIDI

Inkscape is an illustration editor which has everything needed to create professional-quality computer art. You can use it to make diagrams and illustrations, technical drawings, web graphics, clip art, icons and logos. A collection of hands-on tutorials show you how to combine lines, shapes and text of different types and styles to build up a picture.

A selection of powerful vector graphics editing tools comes as standard. There is excellent support for paths, gradients, layers, alpha transparency and text flow control. An extensive library of filters allow you to apply realistic effects and extensions allow you to work with bitmaps, barcodes and printing marks, amongst other things.

Most of the common vector formats are supported, including PDF, Adobe Illustrator and AutoCAD files, and it has unrivalled support for the SVG web graphics standard.

Between the suggested packages:

• dia: to export Dia shapes;
• libsvg-perl: to import .txt files (txt2svg extension);
• python3-packaging: used by the Optimized SVG extension;
• python3-uniconvertor: enables several import/export extensions;
• pstoedit: to work with eps files;
• ruby: there are several extensions written in ruby;

LibreCAD is an application for computer aided design (CAD) in two dimensions (2D). With LibreCAD you can create technical drawings such as plans for buildings, interiors, mechanical parts or schematics and diagrams.

Pencil2D is an animation/drawing software for Mac OS X, Windows, and Linux. It lets you create traditional hand-drawn animation (cartoon) using both bitmap and vector graphics.

The basic features of Pencil2D are:

• layers support (separated layer for bitmap, vector and soud part)
• bitmap drawing
• vector drawing
• sound support

Scribus is an open source desktop page layout program with the aim of producing commercial grade output in PDF and Postscript.

Scribus can be used for many tasks; from brochure design to newspapers, magazines, newsletters and posters to technical documentation.

Scribus supports professional DTP features, such as CMYK color and a color management system to soft proof images for high quality color printing, flexible PDF creation options, Encapsulated PostScript import/export and creation of 4 color separations, import of EPS/PS and SVG as native vector graphics, Unicode text including right to left scripts such as Arabic and Hebrew via freetype. Graphic formats which can be placed in Scribus as images include PDF, Encapsulated Post Script (eps), TIFF, JPEG, PNG and XPixMap(xpm), and any bitmap type supported by QT5.

If you need to use the render frame install the texlive-latex-recommended package (suggested).

XPaint is suitable for producing simple graphics. It does offer some advanced features such as image processing functions and gradient fill.

In the C Script Editor of XPaint, the External editor in the File menu will invoke x-terminal-emulator -e sensible-editor.

The gv package will be needed for PDF/PS reading, netpbm will be needed for external conversion, lpr for printing.

Blender is an integrated 3d suite for modelling, animation, rendering, post-production, interactive creation and playback (games). Blender has its own particular user interface, which is implemented entirely in OpenGL and designed with speed in mind. Python bindings are available for scripting; import/export features for popular file formats like 3D Studio and Wavefront Obj are implemented as scripts by the community. Stills, animations, models for games or other third party engines and interactive content in the form of a standalone binary are common products of Blender use.

Hugin is a panorama photo stitching program. Essentially, Hugin is a GUI frontend for Panorama Tools. Stitching is accomplished by using several overlapping photos taken from the same location, and using control points to align and transform the photos so that they can be blended together to form a larger image. Hugin allows for the easy creation of control points between two images, optimization of the image transforms, and much more.

This package includes the following graphical interfaces, using the command-line tools provided in the hugin-tools package:

• hugin - Hugin panorama creator.
• hugin_stitch_project - Hugin batch stitcher.
• PTBatcherGUI - Batch controller for the stitching process.
• calibrate_lens_gui - Lens calibration tool.

Tgif (originally the "Tangram Graphic Interface Facility") is a classic drawing program for 2D vector graphics. Image objects can be hierarchically constructed out of primitives such as polygons, text, and splines (though the splines Tgif draws are not Bézier curves).

It natively supports PostScript formats suitable for LaTeX, as well as X11 bitmap or (version 1) pixmap formats. Other vector and raster image formats such as SVG and PNG can be handled via filters.

Tgif stores drawings as .obj files and individual building-block objects as .sym files, both in Prolog-compatible fact file format.

XaoS allows you to zoom and pan around a fractal in real time. It can display the animated fractals in graphical or even plain text mode.

It displays the Mandelbrot set or many other fractals and allows you to zoom smoothly into the fractal. Various coloring modes are provided for both the points inside and outside the selected set. In addition, switching between Mandelbrot and Julia fractal types is provided.

Other features include autopilot mode, palette changing, image saving, fractal inversion, filters, and a built in fractal tutorial.

XFig is a menu-driven tool that allows the user to draw and manipulate objects interactively in an X window. The resulting pictures can be saved. If the fig2dev program is installed, which is contained in the fig2dev package, the pictures can be printed on postscript printers or converted to a variety of other formats (e.g. to allow inclusion in LaTeX documents or web pages).

This package contains the xfig program itself.

You should think about installing the fig2dev package to export the graphics to several common formats. You should also think about installing xfig-doc, which contains the documentation and xfig-libs, which contains several clip art libraries.
