removeExifMetadata
public void removeExifMetadata(File src, OutputStream os) throws ImageReadException, IOException, ImageWriteException Reads a Jpeg image, removes all EXIF metadata (by removing the APP1 segment), and writes the result to a stream.- Parameters:
src
- Image file.os
- OutputStream to write the image to.- Throws:
ImageReadException
- if it fails to read the JFIF segmentsIOException
- if it fails to read the image dataImageWriteException
- if it fails to write the updated data- See Also:
-
removeExifMetadata
public void removeExifMetadata(byte[] src, OutputStream os) throws ImageReadException, IOException, ImageWriteException Reads a Jpeg image, removes all EXIF metadata (by removing the APP1 segment), and writes the result to a stream.- Parameters:
src
- Byte array containing Jpeg image data.os
- OutputStream to write the image to.- Throws:
ImageReadException
- if it fails to read the JFIF segmentsIOException
- if it fails to read the image dataImageWriteException
- if it fails to write the updated data
-
removeExifMetadata
public void removeExifMetadata(InputStream src, OutputStream os) throws ImageReadException, IOException, ImageWriteException Reads a Jpeg image, removes all EXIF metadata (by removing the APP1 segment), and writes the result to a stream.- Parameters:
src
- InputStream containing Jpeg image data.os
- OutputStream to write the image to.- Throws:
ImageReadException
- if it fails to read the JFIF segmentsIOException
- if it fails to read the image dataImageWriteException
- if it fails to write the updated data

removeExifMetadata
public void removeExifMetadata(ByteSource byteSource, OutputStream os) throws ImageReadException, IOException, ImageWriteException Reads a Jpeg image, removes all EXIF metadata (by removing the APP1 segment), and writes the result to a stream.- Parameters:
byteSource
- ByteSource containing Jpeg image data.os
- OutputStream to write the image to.- Throws:
ImageReadException

updateExifMetadataLossless
public void updateExifMetadataLossless(File src, OutputStream os, TiffOutputSet outputSet) throws ImageReadException, IOException, ImageWriteException Reads a Jpeg image, replaces the EXIF metadata and writes the result to a stream.Note that this uses the "Lossless" approach - in order to preserve data embedded in the EXIF segment that it can't parse (such as Maker Notes), this algorithm avoids overwriting any part of the original segment that it couldn't parse. This can cause the EXIF segment to grow with each update, which is a serious issue, since all EXIF data must fit in a single APP1 segment of the Jpeg image.
- Parameters:
src
- Image file.os
- OutputStream to write the image to.outputSet
- TiffOutputSet containing the EXIF data to write.- Throws:
ImageReadException
- if it fails to read the JFIF segmentsIOException
- if it fails to read the image dataImageWriteException
- if it fails to write the updated data
-

- Parameters:

public void updateExifMetadataLossy(byte[] src, OutputStream os, TiffOutputSet outputSet) throws ImageReadException, IOException, ImageWriteException Reads a Jpeg image, replaces the EXIF metadata and writes the result to a stream.Note that this uses the "Lossy" approach - the algorithm overwrites the entire EXIF segment, ignoring the possibility that it may be discarding data it couldn't parse (such as Maker Notes).
