The PrintImageLocation.java example does not save any images so I don't know
what bug you are alleging. The images in your file are all stored in 0°
rotation (use PDFDebugger to see that). The rotation that you see (when the PDF
is rendered) is done by applying different transforms in the page content
stream. The rotations applied to your image are 0, -90 (= 270), 180, 90.

> PDFBox PrintImageLocations: Extracts images in wrong orientation

> Key: PDFBOX-5179
> URL: https://issues.apache.org/jira/browse/PDFBOX-5179
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.21
> Environment: Windows 10, Tomcat 9, jdk 1.8_0161
> Reporter: Michael Carell
> Priority: Major
> Attachments: 0137d7db-7ca3-4573-a73a-1386699d922c.jpeg,

>
> The PrintImageLocation class writes images in the original and rotated
> format. I used the algorithm in a image processing application. I found some
> PDF documents, where the extracted pictures have a wrong orientation. I have
> build a document to test that case.
> How to reproduce:
> I have constructed a MS Word document, that contains 4 images with different
> rotation levels (0°, 90°, 180°, 270°). I exported the document to PDF format.
> If you call PrintImageLocation with that PDF, the pictures within the
> document, that are rotated are displayed in in the right order and the
> "rotate" images, have the orientation from the document.
