Hi, I've seen in the update log that in Imagevue X2.1.7, the support of IPTC has been added. How can it be used ?

Actually, in my case it's not. There's nothing to configure ? Or any prequisites ?

The field i'm using is the "Object Name" (the official IIM field for the title). Is it correct ? Maybe you are using the field "headline"

Yes, i found you're using 2#105, which is headline, to fill title for image. Many sofwares use ObjectName and not Headline for titles (lightroom, ps ...).
IMHA you should first use headline and if empty use objectname, or best : let the user choose.

An other improvment would be to sort files with IPTC date field.

Ok i've made change to collect objetname instead of headline, but if the field contains special caracters (à ,é,è...), the title is not fullfilled.

(sorry to flood the topic, but i wanted to let you know of my progress !)

I've made a workaround to my problem (only a workaround for ISO-8859-1 characters).

I've modified 2 files :

- /imagevue/include/ivFileImageClass.php
Previous code :
function _initAttributes()
{
parent::_initAttributes();
if ((is_null($this->getAttribute('title')) || is_null($this->getAttribute('description')))) {
$iptcData = $this->iptcReadData();
if (is_array($iptcData)) {
if (is_null($this->getAttribute('title')) && isset($iptcData['2#105'][0])) {
$title = trim($iptcData['2#105'][0]);
if (!empty($title)) {
$this->setAttribute('title', $title);
$this->_setState(STATE_DIRTY);
}
}
if (is_null($this->getAttribute('description')) && isset($iptcData['2#120'][0])) {
$description = trim($iptcData['2#120'][0]);
if (!empty($description)) {
$this->setAttribute('description', $description);
$this->_setState(STATE_DIRTY);
}
}
}
}

New code (bold charracters added) :

function _initAttributes()
{
parent::_initAttributes();
if ((is_null($this->getAttribute('title')) || is_null($this->getAttribute('description')))) {
$iptcData = $this->iptcReadData();
if (is_array($iptcData)) {
if (is_null($this->getAttribute('title')) && isset($iptcData['2#005'][0])) {
$title = utf8_encode(trim($iptcData['2#005'][0]));
if (!empty($title)) {
$this->setAttribute('title', $title);
$this->_setState(STATE_DIRTY);
}
}
if (is_null($this->getAttribute('description')) && isset($iptcData['2#120'][0])) {
$description = utf8_encode(trim($iptcData['2#120'][0]));
if (!empty($description)) {
$this->setAttribute('description', $description);
$this->_setState(STATE_DIRTY);
}
}
}
}

The replacement of 2#105 (= iptc Headline) by 2#005 (=iptc ObjectName) solve the problem of using ObjectName to fill the title of photos.
The "ut8_encode' function permit to correctly read accentuated characters in iptc title and description (UTF8_Encode convert ISO-8859-1 to UTF-8, it's transparent to ascii characters). => it's just a workaround as it doesn't address all charactersets.

- /imagevue/include/ivIptcParser.class.php
Previous code :
function parse($iptcData)
{
if (is_array($iptcData)) {
$parsedData = array();
foreach ($iptcData as $key => $value) {
if (array_key_exists($key, $this->_allowedTags)) {
$value = count($value) > 1 ? $value : $value[0];
switch ($key) {
case '1#000':
// break intentionally omitted
case '1#022':
$value = hexdec(bin2hex($value));
break;
case '1#020':
// break intentionally omitted
case '2#200':
$value = $this->_getFileFormat(hexdec(bin2hex($value)));
break;
case '1#090':
$value = $this->_getCharacterSet($value);
break;
case '2#000':
$value = hexdec(bin2hex($value));
break;
case '1#070':
// break intentionally omitted
case '2#030':
// break intentionally omitted
...
...
...
case '2#150':
$value = $this->_getAudioType($value);
break;
case '2#130':
$value = $this->_getImageType($value);
break;
}
$parsedData[$this->_allowedTags[$key]] = $value;
}
}

}
$parsedData[$this->_allowedTags[$key]] = $value;
}
}

Some photos already uploaded (and intialized) won't retreive the title because it would already have been set to "". Those photos need to be reuploaded, or the file folderdata.xml need to be modified for each folder by deleting the following lines for the photos concerned :
<file name="xxxxxx.jpg" custom="" title="" description=""></file>

I'm not at all an iptc and/or codeset expert, and i think codeset is really a mess on IPTC, as many people/sofware usually assume it's ASCII.

I'm using lightroom 2. I'm not sure of the charset used, i haven't found a software to read the 1x#090 field, but i know it uses MacRoman encoding on Mac OSX.

Many softare i'm using (i' mwilling to replace them with imagevuex2 ), like Gallery2 (Menalto), Picsengine ...) are using the ObjectName field to store the title.

Sorry to answer so late (i was abroad). I'm not sure LR2 use encoding setting. I haven't a sofware that read the iptc 1x#090 field.
(i've read somewhere that LR3 is encoding in utf8).
