How do I get the ImageSize of the embedded Thumbnail?

[wildgoose]

The thumbnail itself is in

Code Select Expand


${$$info{ThumbnailImage}}


Which is itself a jpg file. Is there a way to get ExifTool to parse this in memory data to give me the ImageSize?

Thanks!

$info = $exifTool->ImageInfo($$info{ThumbnailImage});
print "$$info{ImageSize}\n";
