Remigiusz Malessa updated IMAGING-170:
--------------------------------------
Description:
Good afternoon,
I am posting an issue report as suggested by mr Benedikt Ritter. It's my first
issue report and I've just recently started using the Commons Imaging, so
please go easy on me.
------------------------------------------------
Using Commons Imaging I am reading a Tiff image (will attempt to attach it to
this ticket), then I remove a tag (Focal Plane Resolution Unit) and then I save
the new TiffOutputSet to the system using TiffImageWriterLossless.
The original image is 15MB, the new image (with the Tag removed) is 28MB.
Here's how I do it:
{code:title=RemoveTag.java|borderStyle=solid}
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import org.apache.camel.Exchange;
import org.apache.commons.imaging.ImageFormats;

import org.apache.commons.imaging.formats.tiff.TiffImageMetadata;
import org.apache.commons.imaging.formats.tiff.write.TiffImageWriterLossless;
import org.apache.commons.imaging.formats.tiff.write.TiffOutputDirectory;
import org.apache.commons.imaging.formats.tiff.write.TiffOutputSet;
File tInputFile = new File("/home/rem/TEMP/tags.original.tif");
File toutputFile = new File("/home/rem/TEMP/tags.new.tif");
final BufferedImage image = Imaging.getBufferedImage(tInputFile);
ImageMetadata tMetadata = Imaging.getMetadata(tInputFile);
TiffImageMetadata imageMetadata = (TiffImageMetadata) tMetadata;
outputSet = imageMetadata.getOutputSet();
TiffOutputDirectory exifDirectory = outputSet.getExifDirectory();
exifDirectory.removeField(41488);
ImageFormats format = ImageFormats.TIFF;
Map<String, Object> params = new HashMap<String, Object>();
BufferedImage image = Imaging.getBufferedImage(tInputFile);
byte[] bytes = Imaging.writeImageToBytes(image, format, params);
TiffImageWriterLossless writerLossLess = new TiffImageWriterLossless(bytes);
writerLossLess.write(os, outputSet);
{code}
