Fonts & Character Sets ⇒ rendering Blackboard fonts

[loyola]

hi all

I have a very strange problem of blackboard (mathbb) fonts (for mathematics' N, Z, Q etc) being rendered in an ugly looking font (on some machines on which I install LyX, but not others). Attached PDF files showing the good and the bad. Right now I am stuck with the bad and don't know what to do to get back to a normal looking N for ye olde naturals. Also it is strange that ALL the characters in the "ugly" pdf are rendered raster (not vector) and some (namely the non-math-text) in the "nice" pdf are also not vector. The "nice looking" blackboard font is vector, as desired.

Can anybody make heads or tales of this? I've tried both article and article AMS class, tried with or without following preamble:
\usepackage{mathbbol}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{amssymb}
\usepackage{mathrsfs} %Lets me use the \mathscr{P} command.
\usepackage{stmaryrd}
\usepackage{textcomp}

and tried changing fonts, all to no avail (my desired font is Computer Modern.)

thanks!

The minimal code:

Code: Select all

\documentclass{article}
\usepackage{mathbbol}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{amssymb}
\usepackage{mathrsfs} %Lets me use the \mathscr{P} command.
\usepackage{stmaryrd}
\usepackage{textcomp}
\begin{document}
	  $\mathbb{N}$
\end{document}

gives me a "nice" looking N. This is with TeXlive 2008 (pdfTeX version 3.1415926-1.40.9-2.2 (Web2C 7.5.7)).

Check to see what versions of LyX and LaTeX, and what versions these packages, installed and the different computers, and see if they match. If not, you probably have your culprit.

The fact that the embedded font in your ugly PDF is "No name" is rather suspcious.

thanks frabjous for your reply
i guess it is a problem with PDFTex but still struggling with it...
