cairo_mesh_pattern_curve_to: cairo_mesh_pattern_curve_to

Description Usage Arguments Details See Also

View source: R/cairo-pattern.R

Description

Adds a cubic Bézier spline to the current patch from the current point to position (x3, y3) in pattern-space coordinates, using (x1, y1) and (x2, y2) as the control points.

Usage

1
cairo_mesh_pattern_curve_to(pattern, x1, y1, x2, y2, x3, y3)

Arguments

pattern

[cairo_pattern_t *] a #cairo_pattern_t

x1

[double] the X coordinate of the first control point

y1

[double] the Y coordinate of the first control point

x2

[double] the X coordinate of the second control point

y2

[double] the Y coordinate of the second control point

x3

[double] the X coordinate of the end of the curve

y3

[double] the Y coordinate of the end of the curve

Details

If the current patch has no current point before the call to cairo_mesh_pattern_curve_to(), this function will behave as if preceded by a call to cairo_mesh_pattern_move_to(pattern, x1, y1).

After this call the current point will be (x3, y3).

Note: If pattern is not a mesh pattern then pattern will be put into an error status with a status of %CAIRO_STATUS_PATTERN_TYPE_MISMATCH. If pattern has no current patch or the current patch already has 4 sides, pattern will be put into an error status with a status of %CAIRO_STATUS_INVALID_MESH_CONSTRUCTION.

Since: 1.12

C function prototype: void cairo_mesh_pattern_curve_to (cairo_pattern_t *pattern, double x1, double y1, double x2, double y2, double x3, double y3)
