jPicEdt is a multi-platform vector-based graphic editor for LaTeX and related packages, including eepic and PsTricks.
The LaTeX picture environment is a special environment for inserting simple drawing commands into a LaTeX file.
This environment was obviously not intented to replace more sophisticated graphical formats such as Postscript or PDF (and their associated design tools: Adobe Illustrator, Macromedia Freehand,...), but was merely aimed at easily incorporating small and simple drawings (e.g. graphs, electrical schematics,...)
Yet picture commands are flexible enough to allow one to build rather complicated drawings, including circles, rectangles, lines and vectors, bezier splines.
Besides, using epic/eepic or PsTricks packages largely increases the set of available commands, and amongst other things, allows for shape-filling (and colours with PsTricks) and a better rendering of shapes.
Finally, one of the main benefits of using the picture environment is the ability to incorporate text containing any LaTeX command allowed in LR mode, e.g. equations, arrays or user-defined commands.
Here are some key features of "jPicEdt":
· Every graphical element allowed by the picture environment commands: lines, arrows, circles, boxes.
· Emulated elements, for example lines of any slope (which LaTeX doesn't support natively), circles of any size, ellipses, arcs and polygons. This makes a strong use of the multiput command.
· Nearly every object allowed by the epic/eepic packages (excluding grids and textured filling): dashed lines, filled (whitened, blackened or shaded) ellipses or polygons, arcs,... Using this package is optional.
· Starting from version 1.3.2, nearly every object in the pstricks.sty package (this include : filling with colors, hatches, textures, setting various stroke parameters, rotating texts,...). Support for pst-node.sty and other related packages is either experimental (meaning that you must recompile with a boolean flag turned on) or simply underway.
· Java 1.4 or later
What's New in This Release:
· New features include new objects (parallelograms, extensible Bezier curves, smooth-polygon and interpolating curves, circles/arcs drawn using three points lying on a contour, and polydots with every style attribute supported by PSTricks), new editing capabilities (rotated text, sheared ellipses, Bezier curves special editing tool, and PSTricks custom parameters), a bunch of new BSH scripts, including a new plugin to plot functions from an equation, and a very comprehensive German translation, including the on-line help.
