cairoPsSurfaceCreateForStream {RGtk2}R Documentation

cairoPsSurfaceCreateForStream

Description

Creates a PostScript surface of the specified size in points to be written incrementally to the stream represented by write.func and closure. See cairoPsSurfaceCreate for a more convenient way to simply direct the PostScript output to a named file.

Usage

cairoPsSurfaceCreateForStream(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)

Details

Note that the size of individual pages of the PostScript output can vary. See cairoPsSurfaceSetSize.

Since 1.2

Value

[CairoSurface] a pointer to the newly created surface. The caller owns the surface and should call cairo_surface_destroy 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.
