I have some problems using the package cmbright. It renders pixelated maths symbols. I don't understand since the package is installed in miktex. I compile using pdflatex

Here is the output of upmap --verbose

    I guess it's the usual problem of MiKTeX not updating correctly the map files when Type1 fonts are installed.

  • Thanks. And how can I update the map file :)?

    Using TeX Live instead of MiKTeX? Just joking. ;-) Sorry, but I can't help you. Try tex.stackexchange.com/questions/108447/…

  • Run from the command line (as administrator and as user) updmap --verbose. The switch will let you see which fonts are mentioned in the psfonts databases (psfonts.map and its siblings).

  • Hey, Thanks. I ran the command but it didn't change the pixelated effect. Do you want me to post the output?

Your problem comes from the fact that the cmbright package doesn't include type 1 version of the fonts. The type 1 versions spread over the cm-super (for T1 and TS1 font encodings) and hfbrightpackages. Unfortunately hfbright.map is not mentioned in the default updmap.cfg. I'll report the problem to Christian Schenk. So for now, you'll have to mention it in your personal updmap.cfg. If you don't already have one, you'll to create one, with these lines (or add them if it exists):

# hfbright : type 1 version of cmbright (OT1 encoding and maths)
Map hfbright.map

This file should be located in C:\Users\Your_Name\AppData\Roaming\MiKTeX\2.9\miktex\conf\

Then run updmap, as I said in my comment. It works (note that the text part is pixellated, as I haven't installed cm-super):

  • If hfbright.map exists on the system, then adding \pdfmapfile{=htbright.map} to the document should work without requiring a run of updmap.

  • @egreg: I didn't know that. Thanks for the information. There remains however that hfbright.map should be mentioned in the system updmap.cfg.

    @Bernard Yes, of course. I've seen several problems with MiKTeX not updating the map files correctly on our site.

  • @egreg: I've mentioned some of them, I think. There are two kinds of problems: most of the time, the .map file is mentioned in the system updmap.cfg (even if the font is not installed, as is normal), but updmap.exe is not run at installation, for some reason. It suffices for the user to run it from the command line. The second case is when the .map file is not even mentioned, although it is installed. It's hard for a basic user to understand what's happening, and it should be reported to MiKTeX's site on SourceForge. I did it for this particular case.

    I had the same problem with MiKTeX 2.9 on Windows, but this was fixed when i installed the packages cm-super and hfbright of MiKTeX Package Manager. I don't need to modify any internal file.

If you do not want to change the font (e.g. defined by a template). Install cm-super as written earlier: (do not edit the tex-file) MikTeX cm-super
