cairo_extend_t.Rd#cairo_extend_t is used to describe how pattern color/alpha will be determined for areas "outside" the pattern's natural area, (for example, outside the surface bounds or outside the gradient geometry).
cairo_extend_t
An object of class list of length 4.
Mesh patterns are not affected by the extend mode.
The default extend mode is %CAIRO_EXTEND_NONE for surface patterns and %CAIRO_EXTEND_PAD for gradient patterns.
New entries may be added in future versions.
Since: 1.0
pixels outside of the source pattern are fully transparent (Since 1.0)
the pattern is tiled by repeating (Since 1.0)
the pattern is tiled by reflecting at the edges (Since 1.0; but only implemented for surface patterns since 1.6)
pixels outside of the pattern copy the closest pixel from the source (Since 1.2; but only implemented for surface patterns since 1.6)
