Does anyone have any idea how to rotate images in a folder using a PowerShell script? I'm working on an OCR flow that converts PDFs to images to OCR scan for data to be used in the renaming and moving of the PDFs. The OCR does not seem to work on images rotated 90 degrees. Think of a landscape page scanned as a portrait. So any remaining images after my flow will need to be rotated. I can achieve this through UI manipulation, but I was hoping for a more efficient way.

Rotate Images

If you use the AI Builder OCR Recognize text in an image or pdf then there are ways to manipulate that data so it always reads the text as up-right.

I show an example of how to do this in this extract data from pdfs template: https://community.powerplatform.com/galleries/gallery-posts/?postid=31e67eea-3f73-47b4-95b7-fe4a7b646389

Re: Rotate Images

Hi Jason,

Please refer the below PowerShell script to rotate multiple images in a specific folder:
--------------------------------------------------------------------------------
$path = "FOLDER PATH" #target directory
[System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
Get-ChildItem -recurse ($path) -include @("*.png", "*.jpg") |
ForEach-Object {
$image = [System.Drawing.image]::FromFile( $_ )
$image.rotateflip("Rotate90FlipNone")
$image.save($_)
}
--------------------------------------------------------------------------------

Hope this will help.

Regards
Kaif
