Line break in an SVG object

Question

Hi friends,
I am using an SVG object to create a pdf from BLS.I am assigning a string value to a variable pre-defined in that SVG object.The problem here is i am unable to get carriage return in that string(string is of huge length) which is being displayed on the PDF.It is getting out of the PDF created.I had used 'crlf' but it is not working.Any suggestions on this would be really appreciated.
regards,
Ravi Kumar

Hi, Ravi.
One of the cool things about SVG is that it is nothing more than an XML document!  So, you have two options to achieve what you would like to do:
Solution 1 involves using the animation editor's expression capabilities to meet your needs:
1a) If you can assume a "maximum" number of lines (let's assume 8 line items maximum), you can place all 8 text objects in their correct position on the SVG object (and name the SVG element ID's something like TextLine1,TextLine2, etc.).  In the animation editor, provide 8 input properties (of type String) corresponding to these text values.  In fact, let's call them TextLine1,TextLine2...TextLine8.
1b) In the animation editor, link the these properties to the corresponding text property for each of your 8 SVG elements.
1c) Now, here's the magic part:  link the following expression (adjusted for each text line item) to the "visibility" attribute of each of your 8 SVG elements.
stringif(stringlength(TextLine1) > 0,"visible","hidden")
1d) Then, in your BLS transaction you'll need to split your list of barcode items and loop through them or assign them.  I'm not sure what your query is returning, but I'm sure there's a way, either with the functions or  the web scraper (a RegEx parser) to do what you need.  Let us know more specifics, and we can provide some guidance.
There's one other approach that takes advantage of the fact that an SVG document is nothing more than a special type of XML document.  In this case, instead of "pre-adding" a fixed number of items, you'll simply use the "append XML" link type and a local property of type XML, which will contain your SVG text element, to dynamically add any number of items.
The key with these approach is to dynamically calculate the x and y positions for each text item (usually based on some fixed height), assign these attributes as well as the text content to a Local property, then append this to the SVG.
You have a few choices for how to load the SVG.  One option is the XML Loader.  However, you can mix the capabilities of the AnimatedObject + direct SVG manipulation as well.
Option 2a is to use the XML loader, manipulate the XML with assignment actions, then use the SVG renderer to convert it to an image.
Option 2b is to use the AnimatedObject action, which outputs both XML and an (optional) image - you should turn off "Render Image" in this case.  You can then manipulate the SVG output to add your text items, and send this to an SVG renderer to convert it to an image.
The advantage of approach 2b is that you can use the standard functionality of the AnimationObject to make the easy stuff, and extend it with SVG manipulation for your "super dynamic" stuff.
Hope this helps,
Rick
