How do I convert text into a SVG picture?

Rate this Message:
I have converted a SVG picture to text and placed it in a document next to
the structure file. From there I import it into a text variable: SVG_Doc:=Open document("Text_SVG_Picture.txt") RECEIVE PACKET(SVG_Doc;SVG_Text;32000) CLOSE DOCUMENT(SVG_Doc) But how do I convert the text into a SVG picture? I expect I need to use: $svg:=DOM Create XML Ref(???) SVG EXPORT TO PICTURE($svg;SVG_Picture;Copy XML Data Source ) No doubt I simple question, but help would be greatly appreciated.

Hi,
I'm afraid there might be a slight misunderstanding of the command SVG EXPORT TO PICTURE. I will reiterative what Christian has already pointed out, but from a different perspective. this command, formally named DOM EXPORT TO PICTURE is a utility command for the DOM set of XML commands, to simplify the procedure of converting an XML tree to SVG. it not the only way to create an SVG, but it does come in handy if you already have an SVG XML as DOM. note on SVG: there are two types of SVG in 4D v11 SQL, 1. animatable but not interactive, 2. interactive but not animatable. "both animatable and interactive" should be coming in the next version. 1. you create with SVG EXPORT TO PICTURE, with the option Get XML Data Source. the receiving picture variable will display the rendered image, but the XML continues to belong to the DOM command, so by changing the DOM by command you effectively animate the SVG. 2. you create with SVG EXPORT TO PICTURE, with the option Copy/Own XML Data Source, or, alternatively, BLOB TO PICTURE, READ PICTURE FILE, etc. (i.e. any picture creating command) the command SVG Find element ID by coordinates is functional in this context, allowing the SVG to be interactive. the command SVG EXPORT TO PICTURE, is no different to the following two lines of code; DOM EXPORT TO VARIABLE( $root; $blob ) BLOB TO PICTURE( $blob; $picture; ".svg" ) or DOM EXPORT TO FILE( $root; $document ) READ PICTURE FILE( $document; $picture, ".svg" ) as you are working with PROCESS HTML TAGS, and not DOM, there is not reason to insist on SVG EXPORT TO PICTURE. simply, > PROCESS HTML TAGS($in;$out) BLOB TO PICTURE( $out; $picture; ".svg" ) and you are done. miyako On 2009/11/04, at 6:49, Carl Aage Wangel wrote: > Thanks Christian > But I don't se quit how to make that useful.
