about renderers and exporting figures

Today i was having trouble exporting a figure using the opengl renderer (default for surfaces). To see which renderer a figure is using, use this command:

get(gcf,'Renderer')

The solution was to change the renderer to z-buffer. To do so, just use this command:

set(gcf,'Renderer','zbuffer')

This was necessary to export my carpetplots using the command:

myStyle = hgexport('factorystyle');
myStyle.Format = 'png';
myStyle.Width = 6;
myStyle.Height = 4;
myStyle.Resolution = 300;
myStyle.Units = 'inch';
myStyle.FixedFontSize = 12;
hgexport(h.fig,'filename.png',myStyle,'Format','png')

See my other posts to know more about the carpetplot function.
