ImageIO.read( ) always rotates my uploaded picture
image, java, javax.imageio, multipartform-data, spring-mvc
Solution
ImageIO.read( ) can't read the orientation of the image if it was taken with mobile device.
I used metadata-extractor to read metadata, i think it's a good solution: github.com/drewnoakes/metadata-extractor/wiki
<dependency>
<groupId>com.drewnoakes</groupId>
<artifactId>metadata-extractor</artifactId>
<version>2.7.2</version>
</dependency>
Read orientation filed in exif directory:
ExifIFD0Directory exifIFD0 = metadata.getDirectory(ExifIFD0Directory.class);
int orientation = exifIFD0.getInt(ExifIFD0Directory.TAG_ORIENTATION);
switch (orientation) {
case 1: // [Exif IFD0] Orientation - Top, left side (Horizontal / normal)
return null;
case 6: // [Exif IFD0] Orientation - Right side, top (Rotate 90 CW)
return Rotation.CW_90;
case 3: // [Exif IFD0] Orientation - Bottom, right side (Rotate 180)
return Rotation.CW_180;
case 8: // [Exif IFD0] Orientation - Left side, bottom (Rotate 270 CW)
return Rotation.CW_270;
}
(Rotation is a class from the org.imgscalr.Scalr framework I use ti rotate image).
Problem
I want to create a web application that allow users to upload their image to the server. When they click send, their image will be uploaded to the server (multipart). Before saving, I want to make some operation with the image, so I decided to use .. ImageIO.read(InputStream) to get BufferedImage object here is the code: ``` public static BufferedImage getBufferedImageFromMultipartFile(MultipartFile file) throws APIException { BufferedImage bi = null; try { bi = ImageIO.read(file.getInputStream()); } catch (IOException e) { throw new APIException(ErrorCode.SERVER_ERROR, e); } return bi; } ``` The problem is when I try to upload a picture that has height more than width such as 3264 x 2448 (height x width), the result always an image that has been rotated (2448 x 3264). Is there any solution to solve this problem ? Is this a bug or any defined API specification ? Thx. PS. sorry for my english :D
