I have a requirement of reading the Resolution of any file type in my spring boot application. Is there any way to do this? I search a lot but didn't get any specific answer. could you please help me with this,
Thanks in Advance
My Java code:-
public String getFileInfo(MultipartFile file) throws Exception {
BufferedOutputStream stream = null;
File model = new File();
String extension;
UUID uuid = null;
try {
String fileName = file.getOriginalFilename();
String basePath = documentBase + java.io.File.separator + accountId;
Long fileSize = file.getSize();
uuid = UUID.randomUUID();
this.uploadFilePath = basePath + java.io.File.separator + uuid;
// Make sure file has an extension and the extension is allowed
int i = fileName.lastIndexOf('.');
String[] imageFileExtensions = {"jpg", "png", "gif", "JPG", "PNG", "GIF", "BMP", "bmp", "Webp", "webp"};
if (Arrays.asList(imageFileExtensions).contains(extension)) {
java.io.File uploadedFile = new java.io.File(this.uploadFilePath);
Metadata metadata = ImageMetadataReader.readMetadata(uploadedFile);
Integer imageWidth = null;
Integer imageHeight = null;
if (metadata.containsDirectoryOfType(PngDirectory.class)) {
PngDirectory directory = metadata.getFirstDirectoryOfType(PngDirectory.class);
imageWidth = directory.getInteger(PngDirectory.TAG_IMAGE_WIDTH);
imageHeight = directory.getInteger(PngDirectory.TAG_IMAGE_HEIGHT);
} else if (metadata.containsDirectoryOfType(GifHeaderDirectory.class)) {
GifHeaderDirectory directory = metadata.getFirstDirectoryOfType(GifHeaderDirectory.class);
imageWidth = directory.getInteger(GifHeaderDirectory.TAG_IMAGE_WIDTH);
imageHeight = directory.getInteger(GifHeaderDirectory.TAG_IMAGE_HEIGHT);
} else if (metadata.containsDirectoryOfType(JpegDirectory.class)) {
JpegDirectory directory = metadata.getFirstDirectoryOfType(JpegDirectory.class);
imageWidth = directory.getInteger(JpegDirectory.TAG_IMAGE_WIDTH);
imageHeight = directory.getInteger(JpegDirectory.TAG_IMAGE_HEIGHT);
} else if (metadata.containsDirectoryOfType(BmpHeaderDirectory.class)) {
BmpHeaderDirectory directory = metadata.getFirstDirectoryOfType(BmpHeaderDirectory.class);
imageWidth = directory.getInteger(BmpHeaderDirectory.TAG_IMAGE_WIDTH);
imageHeight = directory.getInteger(BmpHeaderDirectory.TAG_IMAGE_HEIGHT);
}else if (metadata.containsDirectoryOfType(WebpDirectory.class)) {
WebpDirectory directory = metadata.getFirstDirectoryOfType(WebpDirectory.class);
imageWidth = directory.getInteger(WebpDirectory.TAG_IMAGE_WIDTH);
imageHeight = directory.getInteger(WebpDirectory.TAG_IMAGE_HEIGHT);
}
if (imageWidth != null && imageHeight != null) {
model.setDimensionX(imageWidth);
model.setDimensionY(imageHeight);
}
model.setResolution(?)
}
/**

model.setResolution(?) input on this
