Ming is an LGPL'ed Flash 4/5 (TM) movie (SWF) output library with PHP,
Python, Ruby, Perl 5, C and C++ interfaces.
Nathive is a libre software image editor, similar to Adobe Photoshop,
Corel Photo-Paint or The GIMP, but focused on usability, logic and
providing a smooth learning curve for everyone. The project run in
the Gnome desktop environment and anyone is welcome to collaborate
on it with code, translations or ideas.
This project is in the alpha phase, so it is an incomplete work,
unfit for the end user yet. The intention is to achieve a professional
graphic editor progressively without giving up initial usability.
Nathive is written from scratch in C using GTK+, and is designed
to be simple, lightweight, and easy to install and use.
MuPDF is a lightweight PDF viewer and toolkit written in portable C.
The renderer in MuPDF is tailored for high quality anti-aliased graphics. It
renders text with metrics and spacing accurate to within fractions of a
pixel for the highest fidelity in reproducing the look of a printed page on
screen.
MuPDF has a small footprint. A binary that includes the standard Roman fonts
is only one megabyte. A build with full CJK support (including an Asian
font) is approximately five megabytes.
MuPDF has support for all non-interactive PDF 1.7 features, and the toolkit
provides a simple API for accessing the internal structures of the PDF
document. Example code for navigating interactive links and bookmarks,
encrypting PDF files, extracting fonts, images, and searchable text, and
rendering pages to image files is provided.
OpenCSG is a library that does image-based CSG rendering using OpenGL.
OpenCSG is written in C++ and supports most modern graphics hardware.
CSG is short for Constructive Solid Geometry and denotes an approach
to model complex 3D-shapes using simpler ones. I.e., two shapes can be
combined by taking the union of them, by intersecting them, or by
subtracting one shape of the other. The most basic shapes, which are
not result of such a CSG operation, are called primitives. Primitives
must be solid, i.e., they must have a clearly defined interior and
exterior. By construction, a CSG shape is also solid then.
Image-based CSG rendering (also z-buffer CSG rendering) is a term that
denotes algorithms for rendering CSG shapes without an explicit
calculation of the geometric boundary of a CSG shape. Such algorithms
use frame-buffer settings of the graphics hardware, e.g., the depth
and stencil buffer, to compose CSG shapes. OpenCSG implements a
variety of those algorithms, namely the Goldfeather algorithm and the
SCS algorithm, both of them in several variants.
Darktable is a virtual lighttable and darkroom for photographers: an open
source photography workflow application and raw image developer. It manages
digital negatives in a database and lets one view them through a zoomable
lighttable. It also enables one to develop raw images and enhance them.
Darktable tries to fill the gap between many excellent existing free raw
converters and image management tools (such as UFRaw or F-Spot). The user
interface is built around efficient caching of image metadata and mipmaps,
all stored in a database. The user will always be able to interact, even
if the full resolution image is not yet loaded.
All editing is fully non-destructive and only operates on cached image
buffers for display. The full image is only converted during export. The
frontend is written in Gtk+/Cairo, the database uses SQLite3, raw image
loading is done using libraw and rawspeed, high-dynamic range and standard
image formats such as JPEG are also supported. The core operates completely
on floating point values, so darktable can not only be used for photography
but also for scientifically acquired images or output of renderers (high
dynamic range).
gd is a graphics library. It allows your code to quickly draw images
complete with lines, arcs, text, multiple colors, cut and paste from
other images, and flood fills, and write out the result as a PNG, GIF
or JPEG file. This is particularly useful in World Wide Web applications,
where PNG, GIF and JPEG are three of the formats accepted for inline
images by most browsers.
gd does not provide for every possible desirable graphics operation,
but version 2.0 does include most frequently requested features,
including both truecolor and palette images, resampling (smooth
resizing of truecolor images) and so forth.
OpenColorIO (OCIO) is a complete color management solution geared
towards motion picture production with an emphasis on visual effects
and computer animation.
Data Explorer brings together dynamic computational
and rendering tools in a dynamic, programmable framework that enables
users to rapidly create visualizations of highly complex data from
disparate sources.
Data Explorer can be used to add visualization capabilities to
existing applications. It is used by companies and institutions for
applications in a large variety of visualization fields including
computational fluid dynamics, medical imagery, computational
chemistry, and engineering analysis. For example, it is currently
being used to:
* Identify and manage portfolio risk worldwide for a large
multinational banking group.
* Depict oil-flow simulations to improve drilling success-rates and
increase reservoir yields.
* Piece together over 5,000 ceiling fragments from a 1,200-year-old
temple in Peru.
* Help insurance agents identify opportunities to cross-sell product
offerings.
* Visualize developing weather patterns to improve the accuracy of
weather forecasts.
OpenImageIO is a library for reading and writing images, and a bunch of
related classes, utilities, and applications.
There is a particular emphasis on formats and functionality used
in professional, large-scale animation and visual effects work for film.
OpenImageIO is used extensively in animation and VFX studios all over the
world, and is also incorporated into several commercial products.
The OpenJPEG library is an open-source JPEG 2000 library developed in order to
promote the use of JPEG 2000.
The main part of the project consists in a JPEG 2000 codec compliant with the
Part 1 of the standard (Class-1 Profile-1 compliance).
Besides this main codec, OpenJPEG integrates several other modules:
- JP2 (JPEG 2000 standard Part 2 - Handling of JP2 boxes and extended multiple
component transforms for multispectral and hyperspectral imagery)
- MJ2 (JPEG 2000 standard Part 3)
- JPWL (JPEG 2000 standard Part 11)
- JPIP (JPEG 2000 standard Part 9)
- OPJViewer, a GUI viewer for J2K, JP2, JPWL and MJ2 files
