Introduction PosterBrot is a greyscale Mandelbrot set poster generator. It will generate a set of PGM image files, which, when printed, can be combined into a poster. Features - Portable. PosterBrot is written in ANSI C, and can ported to any platform which supports the standard. -  FPU support. Directly uses the MC6888x, if available. - Smooth. PosterBrot colors by escape radius, rather than by escape iteration. This method produces extremely smooth gradients with fewer iterations per pixel. System requirements - AmigaDOS 2.0 - Software suitable for printing PGM images Revision history 1.0 - 1.2 Internal revisions. 1.3 15 Jan 93. First public release. 1.4 21 May 94. Removed progress report buffering. 1.5 31 May 94. Rewrote iteration function in floating-point assembler ( ~17% speed gain ). 1.6 9 June 94. Tightened assembler code, made PC-relative. Removed percentage indicator.
