IM 6.6.8.1 Q16 Mac OSX Tiger.

I was trying to set the precision of fx calculations to 9 significant figures (default seems to be 6) in one of my scripts, but it does not seem to have any effect. Is this still available or am I making a mistake in its use. I was trying to avoid having to put -precision 9 in each fx command line.

I just set MAGICK_PRECISION=9 near the top of my script in the defaults arguments.


Here is a simple test script:

#!/bin/bash

MAGICK_PRECISION=9

pi=`convert xc: -format "%[fx:pi]" info:`
echo $pi

result:
3.14159


Whereas this works:

#!/bin/bash

pi=`convert xc: -precision 9 -format "%[fx:pi]" info:`
echo $pi

results: 3.14159265


Thanks

Hi Fred,
Maybe you need to export MAGICK_PRECISION so that child processes such as convert will inherit the value.

Pete,

Thanks. That works.
