Still have no idea about how to specify fonts in JavaScript fields.

Still have no idea about how to specify fonts in JavaScript fields.

[Zhichu Chen]

Hello everyone,

Thanks for suggesting some great documents last time. But after
looking up in AcroJS Guide, and PDF Reference , etc., I still don't
know how can I use special fonts in a JavaScript field.


My JS code is:
------------------------------------------------------------------------------------------
  function start_clock()
{ var thetime=new Date();
  var nhours=thetime.getHours();
  var nmins=thetime.getMinutes();
  var nsecn=thetime.getSeconds();
  if (nhours<0)   nhours="0"+nhours;
  if (nsecn<10)   nsecn="0"+nsecn;
  if (nmins<10)   nmins="0"+nmins;
  font.Digital = font.CourBI ;
  vv = this.getField("time.clock") ;
  if (vv) { vv.value = nhours+":"+nmins+":"+nsecn;
  vv.readonly = true ;
  vv.textColor = color.red ;
  vv.textFont = font.Digital ; // font.TimesBI Cour HelvB Symbol ZapfD
  this.dirty = false }}

  timeout=app.setInterval('start_clock()',1000);
------------------------------------------------------------------------------------------

I guess there are already some definitions about ``font.CourBI'' but
where can I find the original code of the definition which I can
imitate it to create a new font.

Thanks

\startJScode{oeps}
    var f = this.getField("TestField") ;
    if (f) {
        if (f.textFont == "Times-Roman") {
            f.textFont = "LMRoman12-Regular";
        } else {
            f.textFont = "Times-Roman";
        }
    }
\stopJScode

\setupinteraction[state=start]

\pdfcompresslevel=0

\starttext

\definefield[TestField][text] [TestGroup][][some example text]
\definefield[FontField][check][FontGroup][yes,no][no]

\definesymbol[yes][\strut YES]
\definesymbol[no] [\strut NO]

\setupfield[TestGroup][none][width=10cm]
\setupfield[FontGroup][none][width=3cm,height=2cm,clickin=JS(oeps)]

\field[TestField]

\field[FontField]

abcdefghijklmnopqrstuvwxyz

\stoptext

The problem is that a subsetted font has no known name (prefix is 
random); however, when embedded full it does not work either ("Courier" 
does work).

Maybe there is special trickery needed to let acrobat know what fonts 
can be used. We may as well need some new pdftex code for this.

I cc to Hartmut who is the pdftex teams weird-font-issues wizzard.

Hi, Hans

Thank you for your example.

I just figured out that once PDF cannot find the specified font, it
will look for a truetype font which has the similar font metrics. Now
I know what to do and has just succeeded:

First, I install a truetype font to ConTeXt---by using texfont of
course---so that ConTeXt can use it;
Then specify the field's textFont attribution to the truetype font name;
Finally, it looks all great.

I think it should work on Type1 fonts too.

I hope I can attach all .ttf, .tfm files to you, but it seems that the
mailing list has a 40K limitation.

does not work here, so maybe you need the (Digital) font on your system.

btw, also set a closeaction which kills the clock when you close the 
document, otherwise acrobat will keep running and freeze
