is it possible to generate grayscale png with the c++ interface?
Thank you,

Hi Sinan Tuncer,
Yes. It is like:
... create the chart as usual ....
// reduce the colors to 256 level grey scale
c->makeChart3()->reduceColors(256, true);
// output the chart in PNG
c->makeChart("/path/to/aaa.png");
Hope this can help.
Regards
Peter Kwan |
