/* This script is supplied with the Mand2000 demo and release */ /* versions and may be freely distributed. */ /* Copyright 1993 Cygnus Software. */ /* An ARexx program for creating image panels, to allow calculation */ /* of much higher resolution images for printing. */ /* The maximum size of images that Mand2000 can calculate is set only by the amount of CHIP (graphics) memory on your Amiga. Currently the amount of CHIP memory varies from 512K up to 2MBytes. With 2MBytes of CHIP memory, the largest images you can create are approximately 1600x1200 at 256 colours, or 4000x3500 in black and white. If your memory all fragmented, or other programs are running, it may be impossible to calculate images of this size. Normally this is plenty big enough, as these images are substantially larger than can be displayed on the monitor without scrolling the image (autoscroll). However if you want to print your images, perhaps using ADPro's prefprinter to print multi-page posters to a high-resolution laser printer or the Primera dye-sub printer, much higher resolutions may be desirable. This scripts provides the solution to this problem. This script will break a picture up into a number of different panels (currently either 4, 9, 16 or 25) and calculate these separately. These panels can then either be merged in ADPro (if you have lots of memory or GigaMem) or can be printed individually and then pasted together. To use this script, find the area that you are interested in, set up the palette and the colour mapping option, and set the screen size to a nice large size - this screen size will be used for each panel create by this script. Now select `Calculate Panels' from the user menu. A requester will appear asking how many panels you would like to calculate. Select one of these options, then select the base file name. This filename will be used for saving out the individual panels. If you request 2x2 panels with a base name of `Work:Fractals/BlobPanels' then the individual panels will be saved to: Work:Fractals/BlobPanels.0.0 - upper left Work:Fractals/BlobPanels.1.0 - upper right Work:Fractals/BlobPanels.0.1 - lower left Work:Fractals/BlobPanels.1.1 - lower right The first digit is the x-coordinate of the panel, the second digit is the y-coordinate of the panel. The final question asked by the script will be whether you wish to save graphics data or iteration data. This is VERY important. If you want to use ADPro 2.5's Fractal2000 loader to create 24 bit data from the panels then you MUST save iteration data. Otherwise you will almost certainly want to save graphics data. At this point the script will zoom Mand2000 towards the upper left hand corner of your picture and begin calculating frames. It will run automatically and will continue until you exit Mand2000, you cancel the script (by selecting DoPanels from the user menu) or it finishes calculating all panels. While Mand2000 is calculating panels you may freely use other windows in Mand2000, or other programs on your Amiga. Nifty things: This script can be used as a flashy demo of the power of Mand2000's ARexx interface and of Mand2000's general coolness. To do this, set up to do panels just as normal, but use a substantially smaller window - typically a non-backdrop window on a moderate sized screen. Before starting the script, select 'Show location' from the project window, then zoom the show location window in towards the location box so that the location box almost fills the window. Now when the script is running you will be able to monitor its progress by watching the location box zipping around in response to ARexx's commands. Sometimes you may have to stop panel creation and then resume it at a later date. To resume panel creation, go through all of the steps to begin creating panels, and then use the `SkipPanel' function in the user menu to skip over those panels that have already been calculated. This command has a keyboard shortcut to make it easier to skip over multiple panels. */ portname = address() /* Retrieve the current port name. */ /* If the portname does not start with MAND2000 then this script must */ /* have been run with rx, rather than from Mand2000.
