Patch 6 to Fractint version 20.4 is now available on the Fractint Developer's web sites: www.fractint.org or www.fractint.net This is unrelated to Rich's port. What's new: Added Per Image Settings to the formula parser. When initially selected from the fractal type formula screen, the symmetry and any per image settings are enforced. The per image settings will be saved to PARs and GIFs, and can be changed from the appropriate screen. The possible values for per image settings are the same as the parameters that appear in PAR files, with the exception of 'params='. Params can't be set in the per image settings section, because they get set to zero when the formula is parsed. The formula syntax looks like this: mandel(symmetry)[per image settings] { per pixel settings: iteration bailout } For example: IslandOfChaos(XAXIS_NOPARM)[float=y function=sqr/sin/cosxx] {; Jonathan Osuch ; Generalized by Tobey J. E. Reed [76437,375] ; Try p1=0, p2=4, fn1=sqr, fn2=sin, fn3=cosxx ; Note: use floating point z = p1, x = 1: IF (x < 10) z=fn1(z) + pixel ELSE z=fn2(z) / fn3(z) + pixel ENDIF x = x+1, |z| <= p2 } Jonathan
