Text outline in figure

[lidakal]

Hi experts,

Is there a way to create some outlined text in a TCanvas, like in the attached image?
I am using ROOT 6.30, and have looked around TText, TLatex and TPaveText with no luck.

Thanks in advance,
Lida

Hi Lida,

I am not sure we support this kind of fonts. I perhaps let @olivier comment given his deep knowledge of the matter.

Cheers,

How to add new fonts?

Hi, I would like to know how do I add new fonts to root? Can I use unicode fonts, such as arialuni.ttf? It seem that copy a ttf file to /usr/share/root/fonts/ won’t work. I found that there are some arial*.ttf in /usr/share/root/fonts/, but fonts list in TLatex->SetTextAttributes do not shown any arial fonts, is that normal? Thanks. lihb

Add new font to root

I am wondering about how to add new font to the root. The most newest topic about adding new fonts is nearly 10 years ago in the https://root-forum.cern.ch/t/how-to-add-new-fonts/6732/9. And that topic says that this is a very hard work for root. Is there any update of root that makes adding new font possible or we need to wait for root7 ?

Yes, we do not have this kind of font.

There is one possible way but it will work only for PostScript files and will required the editing of the PS file. It is the following:

1. generate a PostScript file, for instance by running the following macro:

void outlinetext() {
   auto c = new TCanvas;
   auto t1 = new TText(.5,.5,"Outline text");
   t1->Draw();
   c->Print("c.ps");
}

2. open the generated PosScript file (here c.ps) with your favourite text editor.

3. after the line:

%%BeginProlog

insert the line:

/oshow {gsave [] 0 setdash true charpath stroke grestore} def

4. Then search the text you want to see as hollow. In c.ps you will find something like:

... (Outline text) show  ...

5. replace show by oshow and the text will appear as you wish in the Postscript file.

Hi all,

Thanks for the suggestion! I will try this PostScript alternative.
