There are the lines:
xr->left_margin = parse_dimension (opt (d, o, "left-margin", ".5in"));
xr->right_margin = parse_dimension (opt (d, o, "right-margin", ".5in"));
xr->top_margin = parse_dimension (opt (d, o, "top-margin", ".5in"));
xr->bottom_margin = parse_dimension (opt (d, o, "bottom-margin", ".5in"));
Now the comment to parse_dimension says the return value is in 1/72000 of an
inch.
That is in 1/1000 of a point.
Later there is code like:
cairo_translate (cairo,
xr_to_pt (xr->left_margin),
xr_to_pt (xr->top_margin));
and xr_to_pt is defined as:
/* Conversions to and from points. */
static double
xr_to_pt (int x)
{
return x / (double) PANGO_SCALE;
}
This would be correct if PANGO_SCALE was 1000 but on my system it is defined as
1024
Is there an error here somewhere?
