Determine number of text lines

[EricC]

A text box is 2.25 inches wide.
Inside of that text box I have placed a field named 'Title'

Some titles are very long but the text box is tall enough to accommodate up to 5 lines.

Is there a function or rule I can use, that will return the number of lines for any given record as a result of word wrap?

For example:

'Title 1' will fit on one line therefore return '1'

'Here is Title 2 and it's a bit longer' - I want to know if this will end up wrapping to 2 lines or 3 lines. (That is, I want the rule to return '2' or '3')

// Use TextMeasure to get the length of each company name
var tm = new FusionProTextMeasure;
var frameWidth = 2.25; // set width of the text box (in inches)
tm.pointSize = "10 pt"; // set the type size
tm.font = "Helvetica"; // set your typeface
var str = Field("Title"); // set the field to use
tm.CalculateTextExtent(str);
tm.useTags = false;
var tmWidth = tm.textWidth;
var tmNumberofLines = tm.textLines;

return tmNumberofLines;
