Image Conversions via PHP GD Filters Tutorial
Once in the (PHP) GD-land of yesterday’s Image Conversions via PHP GD Primer Tutorial, you’d be mad not to facilitate some image filtering which GD is so good at. And so, we have included an optional usage dropdown as per …
… into the mix. We add this select element “dropdown” within the HTML form method=POST action=”Here’s looking at you kid” arrangement. Initially it gets assigned just an ID attribute, with no NAME attribute, which is an ideal arrangement when functionality is optional. And so, if the user chooses a real “filter” here it gets assigned an appropriate NAME attribute as per the PHP’s Javascript dropdown onchange event logic …
<?php echo ”
function zoomsame(tvo) {
var tv=tvo.value;
var pa=null;
if (tv.trim() == '' && ('' + tv.length) != '0') { aska=true; }
if (tv.trim() != '') {
tvo.name=tv.trim();
if (aska && askastr.indexOf(';' + tv.trim().toLowerCase() + ';') != -1) {
pa=prompt('Optionally enter argument(s) for ' + tv.trim(), askastr.split(';' + tv.trim().toLowerCase() + ';')[1].split(';')[0]);
if (pa != null) {
if (pa.trim() == '') { pa=null; }
}
}
if (pa != null) {
if (('' + pa.split(',').length) == '3') {
document.getElementById('rotation').name='args';
document.getElementById('rotation').value=pa;
} else {
document.getElementById('rotation').name='arg1';
document.getElementById('rotation').value=pa;
}
} else {
document.getElementById('rotation').name='rotation';
document.getElementById('rotation').value='' + document.getElementById('trot').value;
}
if (tv.trim().toLowerCase() == 'redo') {
redo();
} //alert(11);
//}
}
}
“; ?>
… turning a “display useful only” HTML dropdown element into one whose value is transferred with self-navigation to interest the PHP “recall” logic …

Image Conversions via PHP GD Primer Tutorial
Regular readers at this place will know about our admiration for ImageMagick and its command line (“convert” for macOS and Linux and “magick.exe” for Windows) image conversion functionality. Even so, ImageMagick is not capable of …
convert filespec*.*g* *.jpeg
… type of image conversion, in bulk, kind of processing (which Gimp offered with its sadly departed Bimp conversion software in the past). But tailored PHP use of the GD (image manipulation) library, helped out by (good ol’) PHP glob, is!
And so, we’ve written a “proof of concept” converter that you can run at the RJM Programming domain, but we’d recommend for use with an Apache/PHP local web server like MAMP is! (Two in one blog posting is a record … is!)
Get into MAMP, and you might want to download convert_wildcard.php PHP source code to MAMP’s Document Root folder. Else, try it here or below …
