When I make dynamic thumbnails, they are produced as orphans (ie they have no metadata). I am familiar with ways to get IPTC or EXIF data into such thumbnails if you go and actually write the file to disc, however I have more specific problem related to making them dynamically. Below is a snippet of code that is currently being used
// details of orig image
list($width, $height) = getimagesize($file);
// Resizing the Image (make up new modwith and modheight)
$tn = imagecreatetruecolor($modwidth, $modheight);
$image = imagecreatefromjpeg($file);
imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width,
$height);
// Outputting a .jpg,
imagejpeg($tn, null, 80);
What I would like to do is insert some IPTC headers into this exact process without changing the input or output - so the pseudocode for the revised module would be
// details of orig image
list($width, $height) = getimagesize($file);
=== GET THE IPTC HEADERS FROM THE ORIGINAL HERE =========
// Resizing the Image
$tn = imagecreatetruecolor($modwidth, $modheight);
$image = imagecreatefromjpeg($file);
imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width,
$height);
==RE-INSERT THESE IPTC HEADERS =====
// Outputting a .jpg,
imagejpeg($tn, null, 80);
If anyone could help that would be most appreciated. As regards getting the IPTC headers, clearly the php command iptcparse is the one, however I cannot get iptcembed to work. Many thanks
