I have previously posted a number of blogs that, in some way or another, speak to functionality Microsoft deprecated. This blog articulates how you surface at least some EXIF metadata embedded in media-type assets / files with a specific focus on EXIF metadata that may be embedded in photo or image type files.
In Part 2 of this blog series I am now going to describe, again by way of example, how you can equally surface near identical metadata from numerous type of files uploaded to any libraries, but this time using the SharePoint v2 Graph Drive Items REST API.
The solution showcased and shared in this blog demonstrates how some really awesome metadata can be surfaced in a Power App consuming a Flow Automate Flow.
The blog showcases the type of Power Apps that can be created depicting sublime performance rendering high quality and significant optimized thumbnail images and value of this concept in an Attendance Tracking app.
In this blog four alternate techniques are outlined that enable App Makers to render the practically any type of document stored in SharePoint Document Libraries in PowerApps
1. Actual PDF documents ( Basic Flow )
2. Word documents, PowerPoint presentations, HTML files (and numerous other document types) converted to PDF documents on-the-fly
3. Thumbnail images of the documents generated on-the-fly
4. Actual PDF documents
( Advanced Flow with Graph APIs )
The source code for the demo apps showcased in my previous blog, SharePoint Images Powered Up In PowerApps, has been shared on GitHub. For further details wrt this, read more!
This blog post articulates and demonstrates how App Makers can render photos stored in SharePoint Document Libraries leveraging the RenderListDataAsStream REST API within PowerApps.
