Hyde's Advanced Hints in Using World-Wide Web

• If composing HTML, you can check the HTML code with weblint which is on Bucknell's Suns at:

  ~hyde/webtools/weblint

  To check an HTML file, type:

  % ~hyde/webtools/weblint/weblint yourfile.html

• On the Suns, to view .gif images use xv. The program xv will also allow you to alter the .gif image, e. g., to shrink the size or brighten it.

• To create your own .gif, you can scan in a picture, e. g., on a MAC and use Gifconvert or GraphicsConvert on the Mac to convert the PICT file to a gif file.

• On the Suns, you can create your own .gif using xpaint. Neat program! However, I think xpaint is not installed properly as it kept corrupting the new file.

• On the Suns, you can convert Latex documents to html by using latex2html. To convert the file paper.tex to a single file of html, you would type:

      % latex2html -split 0 paper.tex
  

  and a new directory paper will be created with the .html files.

  The manual is at:

       /usr/local/doc/latex2html/manual.ps
  

• To make a gif image's background transparent, use giftrans on the SUNS. You can find giftrans at

          ~hyde/giftrans
  

  Here's what to do.

       % giftrans -V file.gif
  

  will display the color map and a bunch of junk. You look at the color map at the beginning to determine which color is the background color - usually white (which is Color Red 255, Green 255, Blue 255). You need the index for that color (usually 0). Then execute the following:

       % giftrans -t 0 file.gif > newfile.gif
  

  The newfile.gif should be transparent. Look at the new gif in Netscape or Mosaic.
