A strong point of this software is the ability to write the data, copied or not from a source image (reference image), to multiple images at once.
pyExifToolGui is a python pySide QT4 script program that reads and writes all kind of metadata tags from/to image files. PyExifToolGui is a graphical frontend for the excellent open source command line tool ExifTool by Phil Harvey. What’s left is more easy and straigtforward to use.PyExifToolGUI pyExifToolGUI is no longer supported Please switch to jExifToolGUI What I’ve started was oriented too much towards batch-processing (internally it still is, but you can’t use it anymore). Update: if simplified, as suggested by Phil Harvey, the usage of the API. JExifInfo info = tool.getInfo(new File("D:\\Users\\pw999\\Documents\\Development\\Bitbucket\\j-exiftool\\lib\\DSC00216.JPG")) tProperty(ExecutionConstant.EXIFTOOLPATH, "lib\\exiftool.exe") If everything is working correctly, reading an Exif-tags using J-ExifTool should be as simple as: Well documented and correct code (IntelliJ Code inspection + FindBugs + Checkstyle).High performance for processing batches of images.The read functionality is already working pretty okay tough a lot of details are still missing (like formatting and casting the results). This is where J-ExifTool comes in: it’ll be the first Java-library which allows you to read and write Exif-tags by using the ExifTool by Phil Harvey.
It quickly turned out that the best implementations relied on the Perl executable ExifTool by Phil Harvey and a quick look at the documentation told me why: it’s super awesome, it’s super reliable and after many years of development it’s still being updated ! However, this could not be said off the Java libraries which use Exiftool: none of them support writing Exif-tags and only a few are still being developed. A while ago I started looking for a Java library which allowed me to read Exif-tags.
