SVG_Define_solidColor ( parentSVGObject ; id ; color {; opacity} ) -> Function result

Parameter	Type	Description
parentSVGObject	SVG_Ref	Reference of parent element
id	String	Color name
color	String	Color expression
opacity	Longint	Opacity
Function result	SVG_Ref	Color reference

Description

The SVG_Define_solidColor command sets a new custom color in the SVG container designated by parentSVGObject and returns its reference. If parentSVGObject is not an SVG document, an error is generated.

The id parameter specifies the color name. The name will be used to associate a color with an object. If an element with the same name exists, it will be replaced.

The color parameter is a color expression recognized by SVG (see Colors and Gradients).

The optional opacity parameter can be used to specify an opacity (from 0 to 100) for this color. If the parameter is omitted, the opacity will be 100%.

The color set in this way will be associated with the fill or stroke paint by passing the string "url(#ID)" as the value when a color expression is expected.

Example

  `Set blue to 50%

 SVG_Define_solidColor($svg;"MyColor";"blue";50)

 ...

 SVG_New_rect($svg;0;0;20;20;0;0;"url(#MyColor)";"url(#MyColor)")

 ...

 $line:=SVG_New_line(10;10;100;100)

 SVG_SET_STROKE_BRUSH($line;"url(#MyColor)")
