[Plplot-general] plplot_canvas_use_pixmap

[Joe C. <ma...@jo...>]

Hi,

I was using plplot 5.3.1 with plplotcanvas until a few days ago. In that 
configuration I found that I needed to use plplot_canvas_use_pixmap() -- 
otherwise the memory footprint of my application would peak out at about 
2 GB and rendering would be very slow. With plplot_canvas_use_pixmap() 
memory usage never exceeded about 45 MB and rendering was reasonably 
fast. (The plot is a 3d surface with 350 x 512 grid points -- it is a 
profile of a high quality laser beam, and the detail is desired by the 
optical scientists).

With the release of plplot 5.5.0 I see that plplotcanvas is now directly 
incorporated. That was great news to me. However, 
plplot_canvas_use_pixmap() seems to have been removed. I found 
plplot_canvas_use_fast_rendering(), but my app is back to using ~815MB 
memory and rendering very slowly. Without 
plplot_canvas_use_fast_rendering() the situation is even worse -- about 
1.6GB memory use.

So my question -- is there any plan to replace 
plplot_canvas_use_pixmap()? Or am I just plain doing something wrong?

Thanks for any answers or insights.

Joe
