Apache OpenOffice Draw
The powerful graphics package
Draw - from a quick sketch to a complex plan, Draw gives you the tools to communicate with graphics and diagrams. With a maximum page size of 300cm by 300cm, Draw is powerful tool for technical or general posters, etc.
'Park' your most commonly used drawing tools around your screen ready for single-click access.
Use Styles and Formatting to put all your graphics styles at your finger tips.
Manipulate objects, rotate in two or three dimensions; the 3D controller puts spheres, rings, cubes, etc. at your disposal.
Arrange objects: group, ungroup, regroup, and edit objects while grouped. Sophisticated rendering let you create photorealistic images with your own texture, lighting effects, transparency, perspective, and so on.
Smart connectors make short work of flowcharts, organization charts, network diagrams, etc. Define your own 'glue points' for connectors to 'stick' to.
Dimension lines automatically calculate and display linear dimensions as you draw.
Use the picture Gallery for clipart; create your own art and add it to the Gallery.
Save your graphics in OpenDocument format, the new international standard for office documents. This XML based format means you're not tied in to Draw. You can access your graphics from any OpenDocument compliant software.
Import graphics from all common formats (including BMP, GIF, JPEG, PNG, TIFF, and WMF).
Use Draw's free ability to create Flash (.swf) versions of your work.
