Detailed Description

Structure to draw the ALICE logo on a pad (canvas). The logo and text is drawn using ROOT primitives and the result is somewhat scalable.

Note, you can save the logo as a PNG, PDF, or SVG to include it in some other document or the like.

How to use

{
  TH1* h = new TH1F("h", "h", 60, -3, 3);
  h->SetFillColor(kRed+1);
  h->SetFillStyle(3001);
  h->FillRandom("gaus");
  h->Draw();
  
  gROOT->LoadMacro("AliceLogo.C");
  AliceLogo* al = new AliceLogo();
  // al->Draw(0, .75, .4, .25, "preliminary");
  // al->Draw(0, .75, .4, .25, "performance");
  // al->Draw(0, .75, .4, .25, "","text l3 many particles");
  al->Draw(0, .75, .4, .25, "preliminary", "text l3 many particles");
}

There are many options for colours and options for preliminary, performance and just the logo.

The logo produced does not exactly match the logos found on the ALICE web-site

https://aliceinfo.cern.ch/Figure/alice_logo

In particular, the 'C' was hard to get right. However, the logo does follow the charter as described in

http://aliweb.cern.ch/system/files/documents/charter/charte_A5_120628.pdf

Use the static member function(s) AliceLogo::Check to see how well this code reproduces the logos. Note, you need the official logos in PNG format for this. Here's a list of places to get them:
