Package org.freehep.graphicsio.cgm Description

CGM (Computer Graphics Metafile) Output Format.

CGM is a Vector Graphics format, defined by the ISO-IEC-8632-x-1999 standard.

This package provides two low-level writers for CGM files:

• CGMOutputStream for binary .cgm files
• CGMWriter for clear text .cgm files

and a VectorGraphics implementation:

• CGMGraphics2D

The current implementation supports Version 1 CGM.

CGM files can be imported by the following applications:

• Adobe Illustrator
• Adobe FrameMaker
• Microsoft PowerPoint
• Microsoft Word
• Micrografx ActiveCGM plugin for Netscape and Internet Explorer
• Larson WebCGM Viewer

In all these applications both online viewing and printing are supported.

The following limitations exist:

• drawFrameAndBanner not implemented.
• images not implemented.
• text sizes seems to be not perfect
• TestClipping, clipping only works on straight rectangles
• TestPrintColors is wrong
• TestPaint GradientPaint is not supported
• TestPaint TexturePaint is not supported
• TestLineStyles dashing is approximated
• TestImages images not shown
• TestImage2D images not shown
• TestTaggedString same font for all three.
• TestShapes all text in same font.
• TestFonts unicode wrong.
• TestFonts dingbats missing
• TestFonts no monotype corsiva
• TestAll font is wrong.
• TestAll no gradients in banner 2x.
• TestAll no sky.
• TestAll impact font missing, special characters not shown.

Status:

Frozen, Version 1 CGM tags implemented, but format not good enough to properly attach a graphics2d context.
