cairoSvgSurfaceCreateForStream: cairoSvgSurfaceCreateForStream

Description

Creates a SVG surface of the specified size in points to be written incrementally to the stream represented by write.func and closure.

Usage

cairoSvgSurfaceCreateForStream(write.func, closure, width.in.points, height.in.points)

Arguments

write.func
[CairoWriteFunc] a CairoWriteFunc to accept the output data
closure
[R object] the closure argument for write.func
width.in.points
[numeric] width of the surface, in points (1 point == 1/72.0 inch)
height.in.points
[numeric] height of the surface, in points (1 point == 1/72.0 inch)

Value

  • [CairoSurface] a pointer to the newly created surface. The caller owns the surface and should call cairoSurfaceDestroy when done with it.

    This function always returns a valid pointer, but it will return a pointer to a "nil" surface if an error such as out of memory occurs. You can use cairoSurfaceStatus to check for this.
