I have a test.py
script that I use simply this way:
>>> import test
>>>
Inside test.py
:
import cairo
sfc = cairo.SVGSurface("test.svg", 720, 720)
ctx = cairo.Context(sfc)
ctx.set_source_rgb(.5, .5, 1)
ctx.arc(360, 360, 300, 0, 6.28)
ctx.fill()
I get no svg
output until I Ctrl+D
in the console.
Using a context manager (with cairo.SVGSurface("test.svg", 720, 720) as sfc:
) produces the svg
file immediately once module imported. But, in my (larger) project, I declare the surface in a constructor, and drawings are made in a method... so I cannot use the context manager.
How can I "close" the surface?
Per the documentation You call surface.finish() and then surface.flush()
import cairo
sfc = cairo.SVGSurface("test.svg", 720, 720)
ctx = cairo.Context(sfc)
ctx.set_source_rgb(.5, .5, 1)
ctx.arc(360, 360, 300, 0, 6.28)
ctx.fill()
sfc.finish()
sfc.flush()
