----------------------------------------
Hello, sorry for any inconvenience,
I had a knot in the brain.
The algorithm works fine. My test case is wrong. The background ist, that I
tried to reproduce a problem, that I had with an image in an landscape
orientated PDF document. I tried to create a test document that contains images
in different locations. I rotated the images within the document and expected,
that my programm is able to find out the angle by which I rotated them. My
mistake.
> 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.
