It uses a pattern type 2 +% dictionary as fill color and has thus several things to do. This is +% a little bit more complicated than using the '/sh' operator (as +% other pgf shadings do): the surface shading must be positioned +% exactly at the requested coordinates, otherwise it is quite useless. +% +% Since shadings are *not* affected by changes in the canvas +% transformation matrix (shifts, rotations etc), it is necessary to +% pack the shading into a separate xform object which is then rotated +% and translated correctly. +% +% There is just one more transformation necessary: the shift inside of +% the xform. This shift is done using changes in the canvas +% transformation matrix and it is UNDONE in the /Matrix argument of +% the pattern dictionary. This last step can't be done with the /sh +% operator which is why I am using pattern dictionaries. +\def\pgfplotslibrarysurfdraw{% + \begingroup + \setbox\pgfutil@tempboxa=\hbox + {% + \pgfpicture + \pgfplotssys@do@surfshading@fillpaths\pgfplots@loc@TMPa% + \global\let\pgfplots@glob@TMPa=\pgfplots@loc@TMPa + \pgfpathrectanglecorners + {\pgfplotslibrarysurf@corner@sw} + {\pgfplotslibrarysurf@corner@ne}% + \pgfplotslibrarysurfusepath + \endpgfpicture + }% + % + % NOTE : this code was broken due to some driver in pgf.
