#### 2.2.1.5 Object fill and stroke

Graphical object subtypes – lines, boxes, circles, arcs and paths – are drawn with a stroke pattern that can be configured in detail.

Function: object-stroke object

  Returns the stroke settings of the object, which must be a line, box, circle, arc or path `object`. The return value is a list of parameters:

  1. stroke width, as an integer number of world units
  2. cap style, one of the symbols `none`, `square` or `round`.
  3. dash style, one of the symbols `solid`, `dotted`, `dashed`, `center` or `phantom`.
  4. up to two dash parameters, depending on the dash style:
     - for solid lines, no parameters;
     - for dotted lines, dot spacing;
     - for other styles, dot/dash spacing and dash length.

Function: set-object-stroke! object width cap dash [dash-space [dash-length]]

  Set the stroke settings of the object, which must be a line, box, circle, arc or path `object`. The arguments are the same as the contents of the list returned by `object-stroke`. Returns object.

Function: object-stroke-width object

  Returns the integer stroke width of object, which must be a line, box, circle, arc or path `object`.

Function: object-stroke-cap object

  Returns the stroke cap style of object, which must be a line, box, circle, arc or path `object`. The returned value is one of the symbols `none`, `square` or `round`.

Function: object-stroke-dash object

  Returns the dash style of object, which must be a line, box, circle, arc or path `object`. The return value is a list of between one and three parameters:

  1. dash style, one of the symbols `solid`, `dotted`, `dashed`, `center` or `phantom`.
  2. for styles other than `solid`, dot/dash spacing;
  3. for `dashed`, `center` and `phantom`, dash length.

Some types of `object` – boxes, circles and paths – can have their interiors filled with a variety of patterns.

Function: object-fill object

  Returns the fill settings of object, which must be a box, circle or path `object`. The return value is a list of one to six parameters:

  1. fill style, one of the symbols `hollow`, `solid`, `mesh` or `hatch`;
  2. up to five fill parameters, depending on fill style:
     1. none for `hollow` or `solid` fills;
     2. line width, line spacing and line angle (in degrees) for `hatch` fills;
     3. line width, first spacing and angle, and second spacing and angle for `mesh` fills.

Function: set-object-fill! object fill-type . fill-args

  Sets the fill settings of object, which must be a box, circle or path `object`. The arguments are the same as the contents of the list returned by `object-fill`. Returns object.
