Anyone - in JackOTradez's posting to this forum on Sun, 9 Feb 2003 he includes a set of parameters and the formula it refers to. When I use these I get a solid blue screen. In looking at the formula I note that the identifiers 'magxmag' and 'rotskew' are used on the right hand side of equations without their having appeared on the left side of an equals sign to define their value. Are some lines of the formula missing? Or are 'magxmag' and 'rotskew' special identifiers that refer to internal Fractint values like 'pixel', 'rand', fn1 & pi and therefore don't need to be assigned values in the formula? <==<< I did a search for 'rotskew' in the fractint.doc file and also in Bradley Beacham's Formula Tutorial and did not find it so I'm thinking that since it is not in the documentation that it is not likely to be a special identifier. w = h / 0.75 * imag(magxmag) tanskew = tan(imag(rotskew * pi / 180)) Did anyone else have a problem creating the image? If so, did anyone else discover how to correct the problem? <==<< The image sounds interesting - any help would be appreciated. - Hal Lane hallane @ compuserve.com
