Ok, I overlooked that one. However, it would nice if one could use RGB and/or CMYK directly in the various Set...Color TH1D* myHist = new TH1D("myHist", "myHist", 100, 0, 10); myHist->SetLineColor(.123, .456, .789); rather than having to do TColor* myColor = new TColor(10000, .123, .456, .789, "myColor"); TH1D* myHist = new TH1D("myHist", "myHist", 100, 0, 10); myHist->SetLineColor(1000); I guess it's a trick of looking up to see if there's a TColor already with that definition, and if not make one. > Windows maps X11 fonts to Windows fonts as follows: > /______________________________________________________________________________ > void TGWin32::SetTextFont(Font_t fontnumber) > { > /*-*-*-*-*-*-*-*-*-*-*-*-*Set current text font number*-*-*-*-*-*-*-*-*-*-*-* > /*-* =========================== > > fTextFont = fontnumber; > > /*-* List of the currently supported fonts (screen and PostScript) > /*-* ============================================================= > /*-* Font ID X11 Win32 TTF lfItalic lfWeight x 10 > /*-* 1 : times-medium-i-normal "Times New Roman" 1 4 Ok, so Windoze expects a string and two intergers. The issue then, is to translate font specifications of the form -<foundry>-<family>-<weigth>-<slant>-<set width>-<add style>-<pixel size>-<point size>-<resolution x>-<resolution y>-<spacing>-<average width>-<character set> into a string and two intergers, in some generic way perferably. Limiting ROOT to only use 5 fonts I believe is a shame. Therefore, if one could specify a font as TTextAttr::SetFont(const char* foundry, const char* family, const char* weight, char slant, const char* set_width, const char* add_style, int pixel_size, int point_size, int resolution_x, int resolution_y, char spacing, int average_width, const char* charactre_set); and at least when using X, ask the font server to give back the right one. For Windoze, I guess you can ask Windoze font server(?) for the font, based on the <family>, <slant> and <weight> only. It should be noted, that times-medium-i-normal is really an alias in the X font server for something like -*-times-medium-i-normal-*-*-*-*-*-*-*-* If you were able to specify fonts like I suggest, then you could use what ever font you may have on the system (ofcourse they may not be avaliable on your collaborators machines, but that's really your problem, not ROOTs). For example, I have some 200 fonts avaliable from my X font server, and while I will never use all of them, it would be nice to use more then 5 :-) Uh, it still seems odd to me that the regular X fonts does not scale well in the Canvas. I mean, looking at any other application, there seems to be no reason why you can't get them to scale better. I haven't looked in the ROOT source code, so I'm just babling along uninformed, and ignorant of any problems there might be.
