1) download the jar file
2) stick it on the cf classpath, i *think* its {cf_installation}/lib in cf7.
3) might have to stop/restart the cf server service
4) image metadata consists of "directories" containing "tags" so something like
the following will extract those tags per dir:
<cfscript>
// path to image on server
path="c:\cyclingTrips\khlong13\coffinService.jpg";
// lib wants java IO file so...
imgFile=createObject("java","java.io.File").init(path);
metadataReader=createObject("java","com.drew.imaging.ImageMetadataReader");
metadata=metadataReader.readMetadata(imgFile);
exifDirs=metadata.getDirectories();
for (i=1; i <= exifDirs.size(); i++) {
writeoutput("<b>Dir: #exifDirs[i].getName()#</b><br>");
tags=exifDirs[i].getTags();
for (j=1; j <= tags.size(); j++) {
writeoutput("#tags[j].getTagName()# :: #tags[j].getDescription()# <br>");
}
writeoutput("================================================<br>");
}
</cfscript>
if you can't do step 2, have a look at mark mandel's excellent javaLoader
project.
