Re: [sanselan] Writing EXIF data to JPEG
Sorry about the website, I plan on fixing it with the 1.0 release. UserComment is one of the uglier cases, as it uses that GPS string type with a special prefix to distinguish character encodings. Try using TagInfo.Text's encodeValue() method to convert the String to byte[], then pass that to new TiffOutputField(ExifTagConstants.EXIF_TAG_USER_COMMENT, ExifTagConstants.EXIF_TAG_USER_COMMENT.fieldTypes, bytes.length, bytes); Thanks for the help, I can now save a usercomment and the artist field successfully. There is just one tiny little problem that I am now requesting some help for. I am able to put international characters into the artist and usercomment field, however, the usercomment field is not shown in Windows Explorer, but the artist is. I have been searching the internet and found that the byteorder should be little_endian, but that was the default case. Is there some way to put in internation characters in the usercomment field? Here is my current code. I altered yours a bit: TiffOutputSet set = new TiffOutputSet(TiffConstants.BYTE_ORDER_LITTLE_ENDIAN); byte[] bytesComment = ExifTagConstants.EXIF_TAG_USER_COMMENT.encodeValue(TiffFieldTypeConstants.FIELD_TYPE_ASCII, KasperCommentÅ, set.byteOrder); byte[] bytesAuthor = TiffTagConstants.TIFF_TAG_ARTIST.encodeValue(TiffFieldTypeConstants.FIELD_TYPE_ASCII, KasperAuthorÅ, set.byteOrder); TiffOutputField commentField = new TiffOutputField(ExifTagConstants.EXIF_TAG_USER_COMMENT, ExifTagConstants.EXIF_TAG_USER_COMMENT.dataTypes[0], bytesComment.length, bytesComment); TiffOutputField authorField = new TiffOutputField(TiffTagConstants.TIFF_TAG_ARTIST, TiffTagConstants.TIFF_TAG_ARTIST.dataTypes[0], bytesAuthor.length, bytesAuthor); set.getOrCreateExifDirectory().add(commentField); set.getOrCreateRootDirectory().add(authorField); Thanks on beforehand, and thanks for the help so far! /Kasper - To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org
[daemon] ftp access code as service
Hi, I am trying to run a piece of java code that uses apache commons net library to connect to a folder and download some files as a service. The service is installed ok and runs but hangs at the part where it has to connect to a ftp server, no error, no timeouts, just goes silent.

Sorry for asking so many questions :( I hope it is okay.
Yes it's okay :).
Hmm. It does not seem like the XP values work. They do not show correctly.
Anyways, I tried using the code I sent you without special characters:
byte[] bytesComment =
ExifTagConstants.EXIF_TAG_USER_COMMENT.encodeValue(TiffFieldTypeConstants.FIELD_TYPE_ASCII,
KasperComment, set.byteOrder);
byte[] bytesAuthor =
TiffTagConstants.TIFF_TAG_ARTIST.encodeValue(TiffFieldTypeConstants.FIELD_TYPE_ASCII,
KasperAuthor, set.byteOrder);
TiffOutputField commentField = new
TiffOutputField(ExifTagConstants.EXIF_TAG_USER_COMMENT,
ExifTagConstants.EXIF_TAG_USER_COMMENT.dataTypes[0], bytesComment.length,
bytesComment);
TiffOutputField authorField = new
TiffOutputField(TiffTagConstants.TIFF_TAG_ARTIST,
TiffTagConstants.TIFF_TAG_ARTIST.dataTypes[0], bytesAuthor.length,
bytesAuthor);
set.getOrCreateExifDirectory().add(commentField);
set.getOrCreateRootDirectory().add(authorField);
Then the exif tools shows (and so do windows explorer):
IFD0
Artist : KasperAuthor
ExifIFD
User Comment : KasperComment
JFIF
JFIF Version : 1.01
However, trying the same, but adding an å to KasperComment and KasperAuthor
gives the following:
IFD0
Artist : KasperAuthorå
ExifIFD
User Comment : 䭡獰敲䍯浭敮瓃
JFIF
JFIF Version : 1.01
It seems the UserComment has been destroyed. Now it is suddenly chinese
characters!?
Windows explorer shows the artist but not the usercomment.
Is this something to do with ExifDirectory vs RootDirectory?
No, the directory wouldn't affect the output.
Sanselan 0.97:
* doesn't null-terminate ASCII strings (eg. Artist), so you have to
allocate a byte array one element bigger and copy the encoded bytes to
it.
* uses the system locale for ASCII encoding, which is UTF-16LE on
Windows, even though TIFF requires UTF-8
So for ASCII fields instead of using encodeValue(), use
getBytes(UTF-8) and copy to a byte array with one more element (so
that the last element is null) like I showed you in the previous
email.
For UserComment what Sanselan does is autodetect the encoding: this
will work for ASCII and write ASCII, but in 0.97 it wrongly assumed
that the unicode encoding is UTF-8, whereas it's actually UTF-16 with
byte ordering depending on the file's byte ordering. So in 0.97 you
have to encode this manually yourself using a big hack:
byte[] unicodeMarker = new byte[]{ 0x55, 0x4E, 0x49, 0x43, 0x4F, 0x44,
0x45, 0x00 };
byte[] comment = My Comment.getBytes(UTF-16LE); // OR UTF-16BE if
the file is big-endian!
byte[] bytesComment = new byte[unicodeMarker.length + comment.length];
System.arraycopy(marker, 0, bytesComment, 0, marker.length);
System.arraycopy(comment, 0, bytesComment, marker.length, comment.length);
TiffOutputField commentField = new
TiffOutputField(ExifTagConstants.EXIF_TAG_USER_COMMENT,
ExifTagConstants.EXIF_TAG_USER_COMMENT.dataTypes[0], bytesComment.length,
bytesComment);
We can safely conclude from this that there is many reasons why 1.0
needs to be released, and 0.97 needs to die :).

I suppose you are wondering why i need to detect the headers if the record size is known. Actually its a corrupted archive in which the header size is correct, but the body size is not, and so i don't know where the body ends and hence where the next header starts. And i do still need to parse the header to get at things like isDirectory, timestamp. @Sebb : I think it should be possible to do this efficiently as the underlying storage is an array.
