Join Bill Weinman for an in-depth discussion in this video Overview of the solution, part of Code Clinic: C++.
- I call this solution ImageSort,…but it actually has several parts to it.…The first part is to identify the files to be sorted.…This is the part that searches the file system recursively.…Then we have to extract the metadata…from the image file for this I'm using…an open source library called Exiv2,…more about that in a moment.…Once we have the metadata, we need to find…the image caption or description so we can sort by it,…and then we need to display a list of the images…sorted by the image caption.…
I'm using the Exiv2 open source library…to extract the metadata from the image file.…Exiv2 is an open source C++ library…that works on many different types of files…including JPEGs and PINGs.…It reads all the popular types of metadata…including Exif or IPTC and XMP,…and this is important because you really…can't predict what sort of metadata your images will have.…One final note about this library,…Exiv2 is designed to work on UNIX based systems.…
It does work on Windows but it's challenging…to compile it in Microsoft Visual Studio.…
Bill introduces challenges and provides an overview of his solutions in C++. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
