Issue

Image thumbnail is rotated 90 degrees when an image attachment is added in portrait orientation.​

Steps to reproduce

1. Create a case. 

2. Add a portrait mode image as an attachment to the case. 

3. The Thumbnail for the image attachment is displayed rotated by 90 degrees. 

Root Cause 

The Portrait mode image contains EXIF orientation information. The Pega Platform ™ uses javax ImageIO while generating thumbnails. ImageIO ignores EXIF orientation information which prevents the auto-rotate of the thumbnail. The current javax ImageIO library does not support orientation information.  

Solution 

An enhancement request has been logged but has not yet been assigned to a specific release.  This Known Issue document will be updated with release details when the enhancement for this issue is available.

 The currently recommended local change is to display a generic thumbnail instead of the image thumbnail, by taking the following steps: 

If using Document Based attachments: 

1. Save-As the OOTB When rule @baseclass.pyCanGenerateDocumentThumbnail into an application ruleset.  

2. Set the Then condition to return false. 

3. Save the When rule.

If using Non-Document Based attachments: 

1. Save-As the OOTB When rule @baseclass.pyCanGenerateThumbnail into an application ruleset.

2. Set the Then condition to return false.

3. Save the When rule.
