gscan2pdf is a GUI to ease the process of producing PDFs from scanned documents. You scan in one or several pages and create a PDF of selected pages. At maturity, the GUI will have similar features to that of the Windows Imaging program, but with the express objective of writing a PDF, including
... [More] metadata. Scanning is handled with SANE via scanimage. PDF conversion is done by libtiff. Perl is used for portability and ease of programming, with gtk2-perl for the GUI. [Less]
pympress is a little PDF reader written in Python using Poppler for PDF rendering and GTK for the GUI.
The special thing is that it is designed to be a dual-screen PDF reader used during presentations and public talks. If you need to make a presentation using your laptop and an overhead
... [More] projector, you may well like it. You'll have your presentation fullscreen on the projector, and at the same time some useful data on your laptop screen: a view of the current slide, a thumbnail of the next one, a clock, and a time counter indicating for how long you have been talking.
Is it mature?
For now this project is very young but already quite usable. [Less]
GRAL is a Java library for creating high quality plots and charts. Many plot types are available like scatter plots, bubble plots, line plots, time series, area plots, pie charts, and bar charts. Nearly every aspect of a plot's appearance can be adjusted using a settings system.
Additionally, GRAL
... [More] can interchange and process data in various ways: filters can be used to smooth, derive, or rescale data. Several plug-ins allow the import and export of data and graphics to formats like CSV, JPEG, PNG, EPS, PDF, or SVG.
Once a plot is set up it can be integrated into any application. Using the included system of Swing classes the user can interactively pan and zoom a plot. [Less]
Walking Papers is like walking, but with paper. With Walking Papers you can print a map from OpenStreetMap, walk around with it and take notes and sketch improvements - then you scan it in, edit it in Potlatch and then we all have a better map!
Asymptote is a powerful descriptive vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. Asymptote provides for figures the same high-quality typesetting that LaTeX does for scientific text.
