[Scilab-users] exporting Matplot RGB image to vector formats : BUG ?

[Samuel Gougeon]

Hello Antoine,

Just add
gce().image_type = "rgba";

immediately after the Matplot() instruction, without adding a fourth 
layer to gce().data.
This makes the three .svg .pdf and .ps conversions working.

Best regards.
Samuel
