/* Panel loader. */
/*
This script is a companion to Mand2000's DoPanels.mnd2 script.
DoPanels.mnd2 (accessible through Mand2000's user menu as `Calculate
Panels') takes a particular fractal image and recalculates it as a
number of separate panels. Each panel is the same pixel size as the
original, but covers a small portion of the fractal coordinates of the
original.
These separate panels can then be pasted together by ADPro.
This allows you to calculate images larger than can be displayed in
Chip RAM. I have used this to calculate images that are 4000x3200
pixels - I then load these into ADPro, using the fractal loader, and I
get beatiful 24 bit colour.
This script asks you for the upper left image and the size of
the grid. This needn't match what you created. For instance, if you
created a four by four grid of pictures, you can load in the four
corners, each four by four, as separate operations. This is handy if
you are printing a multi-page poster and don't have the RAM to hold
all pages at once.
This script assumes that the pictures were saved with
iteration data, rather than graphics data. To change this to use
graphics data, the IFF loader would have to be used instead of the
Fractal2000 loader.
