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, may be `NULL` to indicate a no-op `write.func`. With a no-op `write.func`, the surface may be queried or used as a source without generating any temporary files.
`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)

Details

Since 1.2

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.
