Declaration [src]

int
vips_sdf (
  VipsImage** out,
  int width,
  int height,
  VipsSdfShape shape,
  ...
)

Description [src]

Create a signed distance field (SDF) image of the given shape.

Different shapes use different combinations of the optional arguments, see below.

shape VipsSdfShape: create a circle centred on a, radius r.

shape VipsSdfShape: create a box with top-left corner a and bottom-right corner b.

shape VipsSdfShape: create a box with top-left corner a and bottom-right corner b, whose four corners are rounded by the four-element float array corners. corners will default to 0.0.

shape VipsSdfShape: draw a line from a to b.

::: tip “Optional arguments” * a: VipsArrayDouble, first point * b: VipsArrayDouble, second point * r: gdouble, radius * corners: VipsArrayDouble, corner radii

::: seealso vips_grey(), vips_grid(), vips_xyz().
