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|borderStyle=solid}
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}
