OK. Almost working. As my Perl is much better than my C these days, I
just can't find the correct syntax:

IImageTool.xs:33: error: cannot convert to a pointer type
IImageTool.xs: In function `SvDrawSettings':
IImageTool.xs:62: error: incompatible types in assignment

where the relevant lines are:

hv_store (hv, "zoom_rect", 9, newSVGdkRectangle (settings- >zoom_rect), 0);

Take the address of the zoom_rect structure member like this:

    newSVGdkRectangle (&settings->zoom_rect)


 if (svp) settings->zoom_rect = SvGdkRectangle (*svp);

You need to dereference the pointed that SvGdkRectangle() returns.

    settings->zoom_rect = *SvGdkRectangle (*svp);

SvGdkRectangle() is implemented as gperl_get_boxed_check(), which does not allow undef, so you should not get a NULL pointer back from it unless something is quite wrong.

The Master in the art of living makes little distinction between his work and his play, his labor and his leisure, his mind and his body, his education and his recreation, his love and his religion. He hardly knows which is which. He simply pursues his vision of excellence in whatever he does, leaving others to decide whether he is working or playing. To him he is always doing both.
