[cairo] "data" in cairo_image_surface_get_data ()

[Nguyen Vu Hung]

Hi,

Can anyone explain what is the "data" when the function

cairo-image-surface-get-data();
#http://cairographics.org/manual/cairo-Image-Surfaces.html#cairo-image-surface-get-data

is returned?

Is it in the format of cairo-surface-t?
#http://cairographics.org/manual/cairo-cairo-surface-t.html#cairo-surface-t

It would be nice if you can provide a simple example of how to use
this function? ( read a PNG file from disk, call
cairo-image-surface-get-data, etc, write PNG to disk ... )
