i'm having trouble Help with editing the OnCopyFit Line Rule

[Nicola]

Hello Everyone,

 

I have used the CopyFit Line rule on a couple of templates and it has worked out great. Now I have a template that I need to use the CopyFit Line rule, but instead of using it to adjust the size of the text I was hoping that I could use it to adjust the tracking. However, I'm not sure how to revise the rule in order to accomplish this. I was hoping that maybe someone could help me revise the following rule. Thanks in advance for any help/suggestions.

 

return CopyfitLine("", Field("Email"), fname="WFM-ScalaSans-Regular", 9, 125, 6.5, false);

Hopefully our friend David Sweet won't mind me re-posting his solution from the old email user forum:

If you're familiar with the CopyFitLine function, try using this custom

function instead...

 

//set justwidth to true for horizontal scaling, false for changing point size
function CopyfitLineHorizontal(str, font, size, width, minimum, justwidth)
{
 var tm = new FusionProTextMeasure;
 tm.maxWidth = -1;
 var newsize, retcode, i;
 var  trackInt = new Array(0, -1, -2, -3, -4, -5);

 basetags = "<f name=\"" + font + "\">";
 newsize = size;
 i = 0;

 do
 {
   tags = basetags;
   tags += (justwidth) ? "<setwidth " : "<z ";
   tags += "newsize=" + newsize + "><tracking newsize=" + trackInt[i] + ">" + str;
   retcode = tm.CalculateTextExtent(tags);
   (i < 5) ? i++ : i=5;
   if (tm.textWidth > width * 100) 
      newsize -= 0.1;
 } while (newsize > minimum && tm.textWidth > width*100 && retcode == 0);

 return tags; // + " " + tm.textWidth + " " + width*100;
}

 

Then create a text rule, with tags turned on, and pass...

 

• str = data field containing the string to alter
  
• font = the font (put it in quotes) using the name that FusionPro recognizes
  
• size = the original point size you want to use
  
• width = width of the text area you want to fit measured in points (72 pts = 1 in)
  
• minimum = the smallest point size you want the text to be in.
  
• justwidth = enter true if you want the text to be "narrowed" down to the "minimum" sized entered, enter false if you want the actual font size shrunk.
  

Examples...

 

An entry in the rule such as...

return CopyfitLineHorizontal("This is an extra long string", "Arial", 10, 110, 
9, true);

 

will return a string with the height of the font still at 10, but the width

narrowed slightly...

'<f name="Arial"><setwidth newsize=9.8><tracking newsize=-2>This is an extra 
long string'

 

 

A similar entry with a false value for the justwidth...

return CopyfitLineHorizontal("This is an extra long string", "Arial", 10, 110, 
9, false);

will return a string with the whole font size "lowered" not just narrowed...

 
'<f name="Arial"><z newsize=9.8><tracking newsize=-2>This is an extra long 
string'

Good Luck.

Hi Dan,

 

Thanks for the post. I'll give it a try. I appreciate the quick reply. As usual your coding skills are amazing.
