Image handling scripts


Wind direction Icons

The following wind direction icons are 14x14 transparent GIF files:

S SSW SW WSW W WNW NW NNW N NNE NE ENE E ESE SE SSE

Wind Direction Icons: download [ see version history ]

You can easily use these icons with the wind direction (example for Weather-Display) by using this PHP code:

<?php
$avgspd = "%avgspd%"; // average wind speed (current)
$dirlabel = "%dirlabel%"; // wind direction (NNE etc)
if (strip_units($avgspd) <= 0.1 ) { echo "Calm";
} else { ?><img src="./images/<?php echo $dirlabel; ?>.gif" height="14" width="14" title="Wind from <?php echo $dirlabel; ?>" alt="Wind from <?php echo $dirlabel; ?>" /> <?php echo $dirlabel; ?>@ <?php echo strip_units($avgspd); ?> mph<?php } ?>

<?php
// strip trailing units from a measurement
// i.e. '30.01 in. Hg' becomes '30.01'
function strip_units ($data) {
preg_match('/([\d\.\+\-]+)/',$data,$t);
return $t[1];
} ?>

Resize Nexstorm.jpg and wasp2.png scripts

This script will resize the nexstorm.jpg graphic and cache the result. It is used on my lightning.php page to force the width of the image to be 640px max (so it fits in the layout of the website). The second script does the same for the WASP2 PNG image.

<img src="resize-nexstorm-image.php" alt="NexStorm Display" width="640" height="445" />

Fetch/resize/cache NOAA Image of the Day script

This script will use the HEAD request for the NOAA Image of the Day URL, and download, resize and cache the image if it is updated on the NOAA server. I use it in my NOAA Image of the Day page.

<img src="resize-NOAA-iod.php" alt="NOAA Image of the day" width="640" height="512" />
