> The /DataSource is still an array.  Try:

>          /DataSource (0.115385 0.75 0.0 0 0.115385 0.0 0.75 1 )

In this case the data must be binary, not ASCII, eg:

<0001020304> = 0x01 0x02 0x03 0x04 etc

To map the integer hex values into the domain of the function output you
must supply a Decode array. Depending on the input, you may also find it
necessary to supply an Encode array as well.
