[Kst] What's the matrix format for plotting in KST ?

[Brisset, Nicolas]

Hi,

I sent an answer to this question a few days ago, but I fear it was blocked by some spam policy...
I just wanted to point out that the netCDF datasource normally also supports matrices.

Sorry for the very slow reply!



The only ascii matrix file formats currently supported by kst are the Netpbm formats supported by QImage, and described in

https://en.wikipedia.org/wiki/Netpbm_format



The major shortcoming of them is that they only support integers from 0 to 255, since they were meant for 8 bit monochrome or 24 bit color images.
