[cairo] userfont question--there is nothing in the pdf

[null]

thank you very much,I found error in my program,before draw one font should use cairo_move_to to go to position. I thought cairo default position is (0,0),so I didn't use cairo_move_to,now It can draw my glyphs

I would first start by changing you render function to draw something 
simple like a box and see if that produces any output. Also have a look 
at the user font test case in the cairo test suite:

   http://cgit.freedesktop.org/cairo/tree/test/user-font.c

It is also helpful to test your code with the image surface in case 
there is a bug in the PDF surface or your PDF viewer.
