<tmdoc-title|Specification of style properties>
|
|
|
|
Each of the fundamental types of graphical objects also admits a certain
|
|
number of style properties which affect the rendering. The following style
|
|
properties exist:
|
|
|
|
<paragraph|Color>This property applies to any of the graphical object types
|
|
and specifies the color.
|
|
|
|
<paragraph|Fill color>This property applies to all graphical object types
|
|
except text and mathematics. It specifies a fill color for the object.

|
|
|
|
<paragraph|Opacity>This property also applies to any of the graphical
|
|
object types and specifies an opacity between 0% and 100%. The default is
|
|
100% and lower opacities will make the object more transparent.

displaying points: solid disks, round circles and squares.

<paragraph|Line width>The line width property applies to all curves (that
|
|
is, to broken lines, polygons, splines, closed splines, arcs and circles).
|
|
By default it is <verbatim|1ln>, the width of the fraction bar in
|
|
mathematical formulas, but any <TeXmacs> length unit can be used instead.
