<\body> 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: This property applies to any of the graphical object types and specifies the color. This property applies to all graphical object types except text and mathematics. It specifies a fill color for the object. <\big-figure||gr-frame|>|gr-geometry||gr-fill-color|pastel red|gr-color|dark magenta|gr-auto-crop|true|||||>||||>>||||>>|||>>>>> Examples of a few closed splines with different colors and fill colors. 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. |gr-frame|>|gr-geometry||gr-grid||gr-grid-old||1>|gr-edit-grid-aspect|||>|gr-edit-grid||gr-edit-grid-old||1>|gr-fill-color|pastel green|gr-color|dark green|gr-opacity|20%|gr-auto-crop|true||||>>|||>>|||>>|||>>|||>>|||>>>>|Examples of the same object with increasing opacities on top of another object.> A few different point styles are supported for displaying points: solid disks, round circles and squares. |gr-frame|>|gr-geometry||gr-fill-color|red|gr-grid||gr-grid-old||1>|gr-edit-grid-aspect|||>|gr-edit-grid||gr-edit-grid-old||1>|gr-point-style|square|gr-text-at-halign|center|gr-auto-crop|true|>|>|>|>>|>>|>>>>|The different point styles for black color and red fill color.> The line width property applies to all curves (that is, to broken lines, polygons, splines, closed splines, arcs and circles). By default it is , the width of the fraction bar in mathematical formulas, but any length unit can be used instead. <\big-figure||gr-frame|>|gr-geometry||gr-grid||gr-grid-old||1>|gr-edit-grid-aspect|||>|gr-edit-grid||gr-edit-grid-old||1>|gr-line-width|5ln|gr-auto-crop|true|||||>|||||>>|||||>>|||||>>|>|>|>|>>>> The same curve using different line widths.
