https://sourceforge.net/p/plplot/feature-requests/15/Recent changes to 15: wingcc driver should support semi-transparent coloursenThu, 16 Jan 2014 19:25:16 -0000https://sourceforge.net/p/plplot/feature-requests/15/?limit=25#ac20<div class="markdown_content"><p>You expressed concern privately that the GDI graphics used by wingcc might not support semi-transparent colours. I have looked further into that.</p> <p>Please take a look at <a href="http://msdn.microsoft.com/en-us/library/dd183458" rel="nofollow">http://msdn.microsoft.com/en-us/library/dd183458</a>(v=vs.85).aspx. It appears to me they are essentially documenting colour transparency although they are referring to it as colour mixing.</p> <p>Apparently GDI is quite old/deprecated. If the above idea does not work, another possibility is to move wingcc to GDI+ instead (assuming from the name that move would only be a small amount of work). For the GDI+ case, the colour transparency is documented at <a href="http://msdn.microsoft.com/en-us/library/ms533803" rel="nofollow">http://msdn.microsoft.com/en-us/library/ms533803</a>(v=vs.85).aspx</p></div>Alan W.
