When a Java mobile phone uploads a picture for watermarking, the picture is flipped 90 degrees.

Problem background: When uploading pictures on the mobile phone and printing watermarks in the background, it was found that the pictures were flipped 90 degrees, and the picture upload in the window was indeed displayed normally. Solution: 1. Reference dependencies: <dependency> <groupId>com.drewnoakes</groupId> <artifactId>metadata-extractor</artifactId> <version>2.7.2</version> </dependency> 2. Obtain the flip angle of the image, correct it, […]
