Pattern style 3004 looks different on screen and when saved into pdf

[yus]

Hi,

this page claims the pattern style 3004 should look like this (with lines going from left to right from bottom to top):

Indeed, when I execute the following script in ROOT 6.26/04

        TCanvas* atlas_rectangular = new TCanvas("atlas_rectangular", "c1", 0., 0., 800, 600);
        TH1I* h = new TH1I("h", "My histogram;X;Y", 10, 0., 10.);
        h->Draw();

        TBox *box = new TBox(1., 0.2, 5., 0.5);
        box->SetFillStyle(3004);
        box->SetFillColor(kBlack);
        box->Draw();

        atlas_rectangular->SaveAs("fs3004.pdf");

, I get the expected picture on the screen

but in the pdf file the pattern is reversed, looking like 3005 (lines go from left to right from top to bottom):

Can somebody please look into this?

Thanks!
