75 /**
76  * The Cairo library is a
77  * vector graphics library with a powerful rendering model. It has such
78  * features as anti-aliased primitives, alpha-compositing, and
79  * gradients. Multiple backends for Cairo are available, to allow
80  * rendering to images, to PDF files, and to the screen on X and on other
81  * windowing systems. The functions in this section allow using Pango
82  * to render to Cairo surfaces.
83  *
84  * Using Pango with Cairo is straightforward. A PangoContext created
85  * with pango_cairo_font_map_create_context() can be used on any
86  * Cairo context (cairo_t), but needs to be updated to match the
87  * current transformation matrix and target surface of the Cairo context
88  * using pango_cairo_update_context(). The convenience functions
89  * pango_cairo_create_layout() and pango_cairo_update_layout() handle
90  * the common case where the program doesn't need to manipulate the
91  * properties of the PangoContext.
92  *
93  * When you get the metrics of a layout or of a piece of a layout using
94  * functions such as pango_layout_get_extents(), the reported metrics
95  * are in user-space coordinates. If a piece of text is 10 units long,
96  * and you call cairo_scale (cr, 2.0), it still is more-or-less 10
97  * units long. However, the results will be affected by hinting
98  * (that is, the process of adjusting the text to look good on the
99  * pixel grid), so you shouldn't assume they are completely independent
100  * of the current transformation matrix. Note that the basic metrics
101  * functions in Pango report results in integer Pango units. To get
102  * to the floating point units used in Cairo divide by PANGO_SCALE.
103  *
104  * $(DDOC_COMMENT example)
