Graphics, Figures & Tables ⇒ TeXnicCenter and GasTeX

[Goyatuzo]

I'm completely new to LaTeX, and I've searched all over Google trying to find a similar situation I'm having. I may be searching the wrong key words, but nonetheless I'm unable to find a solution to this problem.

I'm using MikTeX 2.9 and I'm using the gastex.sty file that is given by MikTeX. I did not manually install gastex.sty. As an IDE, I am using TeXnicCenter 2.0 Alpha 4.

Initially I tried to compile ex-gastex.tex they have in gastex's website, which they say should be used to test installation. I used LaTeX -> DVI and I noticed there were 14 warnings after I compiled it. I looked what those warnings were precisely and it says:

Code: Select all

latex> Package gastex Warning: Parameter loopwidth undefined on input line 13.

here is line 13:

Code: Select all

\drawloop[loopwidth=4](A){}

The other warnings are the same, except there are 5 consecutive instances where loopheight is causing the problem.

Code: Select all

  \begin{picture}(118,28)(-7,-11)
%     \put(-7,-11){\framebox(118,28){}}
    \node(A)(0,0){1}
    \drawloop[loopwidth=4](A){}
    \drawloop[loopwidth=6](A){}
    \drawloop[loopwidth=8](A){}
    \drawloop[loopwidth=10](A){}
    \drawloop[loopwidth=12](A){}
    
    \node(B)(20,0){2}
    \drawloop[loopheight=4](B){}
    \drawloop[loopheight=6](B){}
    \drawloop[loopheight=8](B){}
    \drawloop[loopheight=10](B){}
    \drawloop[loopheight=12](B){}
    
    \node(C)(40,0){3}
    \drawloop[loopdiam=4](C){}
    \drawloop[loopdiam=6](C){}
    \drawloop[loopdiam=8](C){}
    \drawloop[loopdiam=10](C){}
    \drawloop[loopdiam=12](C){}
    
    \node[Nw=4,Nh=4](D)(70,0){4}
    \drawloop[loopangle=0](D){}
    \drawloop[loopangle=90](D){}
    \drawloop[loopangle=180](D){}
    \drawloop[loopangle=270](D){}
    
    \node[Nw=4,Nh=4](E)(100,0){5}
    \drawloop[loopwidth=6,loopangle=0](E){}
    \drawloop[loopwidth=6,loopangle=90](E){}
    \drawloop[loopwidth=6,loopangle=180](E){}
    \drawloop[loopwidth=6,loopangle=270](E){}
  \end{picture}

loopangle and loopdiam do not seem to cause issues.

I ignored the warnings and just hit ctrl+shift F5 to view the file, and I saw this (the output file is on the right corner):

TXC-GasTeX.png (264.71 KiB) Viewed 1328 times

However, when I print the file out, everything is what it's supposed to be; it looks exactly like the output file gastex has on their website. So I'm confused whether there is a compiler issue at hand, or if there is an issue with the previewer.

Does anyone know of any solutions to this problem?
