Hi, we are using Plplot on a project with Keras, where we are required to
feed plots as RGBA encoded string plot. Is it possible to do this
somehow ?
I have read about plsmema( )
http://plplot.sourceforge.net/docbook-manual/plplot-html-5.15.0/plsmema.html
But this looks to be a way to input, not to output ?
Hi Xavier:
Yes, plsmema is input so I don't think it is suitable for your described
needs.
Sorry it isn't clear to me what is meant by input here, so I will plow
ahead. The function plsmema sets the memory space for the memcairo to
use when plotting. So it is input in the sense that you pass it a
pointer to the memory where you want the plot rendered. But it is also
output in the sense that the memcairo drive will fill this memory with
the plot image. If you then saved this block of memory as an (RGBA)
image you would see the plot. If you are looking to pass pictures of
plots to Keras then might be what you are looking for.
Though not a "official example", there is a Python example that uses
this function:
plplot/examples/python/test_plsmem.py.in
