Detailed Description

View in nbviewer Open in SWAN
This macro draws all the high definition palettes available in ROOT.

It generates a png file for each palette and one pdf file, with a table of content, containing all the palettes.

In ROOT, more than 60 high quality palettes are predefined with 255 colors each.

These palettes can be accessed "by name" with gStyle->SetPalette(num). num can be taken within the enum given in the previous link. As an example gStyle->SetPalette(kCividis) will select the following palette.

TCanvas *c = nullptr;
void draw_palette(int p, TString n)
{
delete c;
c = new TCanvas("c","Contours",0,0,500,500);
TF2 *f2 = new TF2("f2","0.1+(1-(x-2)*(x-2))*(1-(y-2)*(y-2))",0.999,3.002,0.999,3.002);
f2->SetContour(99);
f2->SetLineWidth(1);
f2->Draw("surf1z");
// Title
TPaveText *pt = new TPaveText(10,11,10,11,"blNDC");
pt->SetName("title");
pt->Draw();
TString num = n;
num.ReplaceAll(" ","");
TLatex *l = new TLatex(-0.8704441,0.9779387,TString::Format("Palette #%d: %s #scale[0.7]{(#font[82]{k%s})}",p,n.Data(),num.Data()));
l->SetTextFont(42);
l->SetTextSize(0.035);
l->Draw();
c->Update();
c->Print(TString::Format("palette_%d.png", p));
