Section for Week 9, Thursday, 3/11/99

1.  ERRATA
    a) 'font-color' from last section should be 'color'
    b) 100..900 from last time refers to weight, not size

2.  MISC
    a) using TARGET attribute in a FRAME tag allows result of click to go to
       alternate frame.  Special values:
       _top == toplevel browser window
       _blank == new window
       _parent == up one level of nesting among FRAMESETs
       _self == this frame
    b) <LINK REL="StyleSheet" TYPE="text/css" HREF="mystyle.css">
       only rules inside mystyle.css...
       REL means "relationship" -- can also be "Alternative StyleSheet" --
             curreent browsers don't support alt sheets.
    c) <P STYLE="color: green">

3.  LA#7:
    Q's?  
    Images go in public_html/ (and need to be world readable).	
    Passwords go in password file, which *can* be mentioned in the CGI.
    It's the actual login/pw's that must not be contained in the CGI.

4.  Imagemaps:
    Specify points as horiz, vertical distances (upper left, lower right).
    See this in action at:

    <IMG SRC="http://www.math.ucla.edu/~fischman/sample.gif" 
         usemap="#infomap" ALT="Information imagemap"></A>
    <MAP NAME="infomap">
    <AREA SHAPE="RECT" COORDS="0,0,125,74"
          HREF="http://www.pic.ucla.edu/" ALT="PIC">
    <AREA SHAPE="RECT" COORDS="125,0,250,74"
          HREF="http://www.math.ucla.edu/" ALT="Math">
    <AREA SHAPE="RECT" COORDS="0,74,125,217"
          HREF="http://www.math.ucla.edu/~fischman/ta/notes/" ALT="Notes">
    <AREA SHAPE="RECT" COORDS="125,74,250,217"
          HREF="http://www.math.ucla.edu/~fischman/ta/solutions" ALT="Homework">
    <AREA SHAPE="RECT" COORDS="0,217,250,292"
          HREF="http://www.ucla.edu/" ALT="UCLA">
    </MAP>

    Add an HREF to the IMG tag for browsers that don't support the AREA tag
    (aka client-side imagemaps).  Also works with no imagemap images.

    If you want to create your own images on unix, you can do so by using
    the Xwin-32 program on NT to log into your account, and launch "xfig".
    Draw your drawing there, and then, once you're done with it, use 
    "xwd > filename.xwd" to dump the xfig window in raw bitmap format.  You
    then to use the magical incantations:
    xwdtopnm filename.xwd > filename.pnm
    pnmtops filename.pnm 
    pstogif filename.ps
    This will produce filename.gif which you can then put on a web page.  To
    find out the coords for the imagemap, use "xv" (middle-mouse-click to
    get coordinates).
