RGtk2 (version 2.20.31)

cairoCreate: cairoCreate

Description

Creates a new Cairo with all graphics state parameters set to default values and with target as a target surface. The target surface should be constructed with a backend-specific function such as cairoImageSurfaceCreate (or any other cairo_backendsurfaceCreate() variant).

Usage

cairoCreate(target)

Arguments

target
[CairoSurface] target surface for the context

Value

Cairo] a newly allocated Cairo with a reference count of 1. This function never returns NULL. If memory cannot be allocated, a special Cairo object will be returned on which cairoStatus returns CAIRO_STATUS_NO_MEMORY. You can use this object normally, but no drawing will be done.

Details

This function references target, so you can immediately call cairoSurfaceDestroy on it if you don't need to maintain a separate reference to it.
