SVG_Open_picture ( picture ) -> Function result

Parameter	Type	Description
picture	Picture	4D picture field or variable
Function result	SVG_Ref	Reference of SVG document

Description

The SVG_Open_picture command analyzes an SVG picture and returns an SVG reference for this picture. If picture does not contain an SVG picture, the command returns an empty string.

Important: Once you no longer need it, remember to call the SVG_CLEAR command with this reference in order to free up the memory.

Example

 READ PICTURE FILE("";$picture)

 If(OK=1)

    $ref:=SVG_Open_picture($picture)

    ...

    SVG_CLEAR($ref)

 End if
