Pho is a lightweight utility for viewing, rotating, or deleting large
numbers of images quickly, and making notes about what to do with each
of them. It is particularly useful for processing hundreds of images
after uploading them from a digital camera.
This is primarily a library for reading portable bitmap (PBM),
portable graymap (PGM), and portable pixmap (PPM) files. These image
formats are only the barest step up from raw data, and have a very
simple format which is the key to be "portable". Writing out images in
these formats is very easy.
SVG::Graph is a suite of perl modules for plotting data. SVG::Graph
currently supports plots of one-, two- and three-dimensional data, as
well as N-ary rooted trees.
SVG::Graph 0.01 is a pre-alpha release. Keep in mind that many of the
glyphs are not very robust.
This is a flexible, command-line-oriented frontend to Gnuplot. It
creates plots from data coming in on STDIN or given in a filename
passed on the commandline. Various data representations are supported,
as is hardcopy output and streaming display of live data.
Partio is a library for reading/writing/processing particle files for a wide
range of tools and file formats. It acts as an abstraction for the
commonalities in particle models (i.e. accessing many attributes associated
with an index or entity).
deegree's Web Coverage Service (WCS) is able to read coverages from
different storage formats and deliver it to any client that is able to
perform an according HTTP GET or POST request. At the moment supported
formats are limited to several raster data formats; but in general a
coverage has not to be a raster dataset at all.
Peps will preprocess encapsulated Postscript files for conversion by
Ghostscript into bitmaps. It provides variable levels of resolution and
anti-aliasing. You can use it as a stand-alone Postscript-to-bitmap
conversion program, or use it on-line to create bitmaps on the fly and send
them out to a web browser, even compressing them if the browser supports
gzip compression.
Pngnq is a tool for quantizing PNG images in RGBA format.
Pngnq is an adaptation by Stuart Coyle of Greg Roelf's pnqquant using
Anthony Dekker's neuquant algorithm.
The neuquant algorithm uses a neural network to optimise the color map
selection. This is fast and quite accurate, giving good results on many
types of images.
Poppler is a fork of the xpdf PDF viewer developed by Derek Noonburg
of Glyph and Cog, LLC. It provides PDF rendering functionality as a
shared library, and uses modern components from Freedesktop.org such as
fontconfig and cairo to take advantage of modern UNIX desktops.
Toyplot is a kid-sized plotting toolkit for Python with grownup-sized goals:
* Develop beautiful interactive, animated plots that embrace the unique
capabilities of electronic publishing and support repoducibility.
* Create the best possible data graphics out-of-the-box, maximizing data ink
and minimizing chartjunk.
* Provide a clean, minimalist interface that scientists and engineers will
love.
