EXIF, UserComment and UNICODE. Format???

I am trying to write the image description into the EXIF UserComment tag as UNICODE. Unfortunately, in the TIFF6 and EXIF file format description, there is no specification for the format to use for the UNICODE characters. Is it 2-byte LE, 2-byte BE, UTF-8, UTF-16, ??? Photoshop seems to treat this tag as some 2-byte characters, at least when changing the byte order of the file (for example when reading DNG and storing as TIFF), the bytes of the UserComment tag get swapped too. However, since the tag is of the type "Undefined", byte swapping should not take place. I tried to add little endian, big endian and UTF-8 byte marks, but the text still gets messed up. So, what is the correct format for this tag? Does it help to store the comment as undefined (8 * 0x00 as format identifier) and then use the appropriate byte marks for the text string? A related problem: Why does Photoshop remove the GPS tag when reading a DNG file and then storing as TIFF, but retains the tag when storing as JPEG? Does not make much sense to me...

What are you using to do this? The EXIF 2.2 file format standard provides for an 8 byte character code string, one of which is for Unicode, namely the ASCII bytes for U, N, I, C, O, D, E, \x0. The EXIF 2.2 standard is dated April 2002, and it simply refers to "the Unicode standard". The latest version of the Unicode standard at that time was 3.2.0, which is dated March 2002. Obviously, no encoding developed after that time would be what EXIF expects.
After typing that, I did a google search for EXIF+usercomment and came up with a useful posting at http://mail.kde.org/pipermail/digikam-devel/2006-May/005000.html , relating to a tool called exiv, which states:
>Unicode support for JFIF and EXIF comments:
>
>- use UTF8 for JFIF comment
>- use Unicode (UCS-2) to write JPEG UserComment,
> support charset specification when reading the UserComment
> - add convertCommentValue method to DMetaData
>
>Using UTF8 for JFIF is simple and easy and should work.
>The UCS-2 support needs testing (and a decision if we
>always want to write Unicode, or a way to find out when we need to
>and when we can as well write ASCII)
So maybe use UCS-2 (UTF-16)?

Export Excel Table in .txt File with space delimited text in UNICODE Format

Hi all
I've a big unsolved problem: I would like to convert an Excel table with some laboratory data in it (descriptions as text, numbers, variables with some GREEK LETTERS, ...). The output should be a formatted text with a clear structure. A very good solution is
given by the converter in Excel "Save As" .prn File. All works fine, the formattation is perfect (it does not matter if some parts are cutted because are too long), but unfortunately the greek letters are converted into "?"!!!
I've tried to convert my .xlsx File in .txt File with formatting Unicode and the greek letters are still there! But in this case the format is not good, the structure of a table is gone!
Do you know how to save an Excel file in .prn but with Unicode formatting instead of ANSI or a .txt with space delimited text?
Thanks a lot to everyone that can help me!
M.L.C.

This solution works in Excel/Access 2013.
Link the Excel table into Access.
In Access, right-click the linked table in the Navigation Pane, point your mouse cursor to "Export", and then choose "Text File" in the sub-menu.
Name the file, and then under "Specify export options", check "Export data with formatting and layout". Click "OK".
Choose either Unicode or Unicode (UTF-8) encoding. Click "OK".
Click "Close" to complete the export operation.

SetString() and Unicode to ASCII/ISO conversion

Hi,
I encountered next problem. My database works in ISO-Latin-1 character set. Still, if I call PreparedStatement.setString(String arg) I would expect this call would convert arg parameter to ISO-Latin-1 using standard conversion mechanism. But after some testing I found out that instead of converting Java characters Oracle's driver just skips hi-byte. So if I have character with hex code 0x2019, which is absolutely normal unicode character. Oracle's driver converts it into 0x19 code, which is not even printable character and not valid ASCII code. Java's standard CharToByteConverter gives 0x63 ('?') code, which, at least, is valid ASCII/ISO-1 character.
And some soft reports "Invalid Character" errors encountering 0x19 and other such codes.
Here's a fragement from Oracle's JDBC log:
DBCV DBG2 UCS-2 bytes (10 bytes):
20 19 20 1c
DBCV FUNC DBConversion.stringToAsciiBytes(str)
DBCV DBG2 DBAccess bytes (5 bytes):
19 1c
Has anyone encountered this problem? Has anyone found work-around?
Checking and converting all strings before calls to setString() would be too overwhelming.
Thanks,
Dmitry

You may not store a string as ASCII values.
Any string you create is stored in Unicode.
The first 128 elements of Unicode are the same as ASCII.
If you want the ASCII representation of the letter "a", then:
System.out.println( java.lang.Character().getNumericValue( 'a' ) );
As DrClap said, there is no reason to save a string in ASCII format since it will be saved in unicode format and thus Java already knows what the ASCII values will be.
If you want to output a string in ASCII format, do it like this:
public Vector convert( String input ) {
StringBuffer tmpIn = new StringBuffer( input );
Vector tmpOut = new Vector
for ( int index = 0; index < tmpIn.length; index++ ) {
char tmpCharacter = tmpIn[ index ];
int tmpValue = java.lang.Character().getNumbericValue( tmpCharacter ) );
tmpOut.addElement( tmpValue );
return tmpOut;
And then display each element as you see fit.
Fixing the bugs in this code is an exercise for the reader. If you want to do something like this, you should be thinking about why you want to do this as well as how to do this.

SAP SCRIPT FORMS with UNICODE FORMAT ??

Hi guru's,
this is sunny newly joined in sap forum,am ABAP doveloper .
now am extensivelly working on upgrradation project(4.6B TO ECC6.0) , my work perticularlly on UNICODE
>> now am working on SAP SCRIPT FORMS, so could you please let me know how to check the scripts in UNICODE FORMAT .
>> Is that usefull to check with UCCHECK
Its urgent
Best Regards

SAP Scripts needs no checks. but you have to keep attention to the fact, that the spoollists must be converted manually by a report written by SAP, and this report is not able to transform sapscripts which are still in the spool. After unicode conversion every sapscript spoollist is lost!

What is diff in Open SQl and Unicode

Hi.
What is difference in Open SQl and Unicode.
What are advantages of Unicode ?

hi osk,
<b>u cant compare open sql with unicode as both are different..</b>
just a small explanation..
<b>Open SQL</b> consists of a set of ABAP statements that perform operations on the central database in the R/3 System. The results of the operations and any error messages are independent of the database system in use. Open SQL thus provides a uniform syntax and semantics for all of the database systems supported by SAP. ABAP programs that only use Open SQL statements will work in any R/3 System, regardless of the database system in use. Open SQL statements can only work with database tables that have been created in the ABAP Dictionary
<b>unicode</b>
Data types such as CHAR ASCII and CHAR EBCDIC are mainly suited to English and central European languages. With other character sets, a code attribute is usually used for these data types. This code attribute uses a different presentation code to ASCII and EBCDIC, even for internal storage in the database system. This causes problems if you want to access these database systems using a different character set, or if you want to exchange data between database systems with different character sets.
You can avoid these problems by using internal character coding in accordance with UNICODE. Internally, the UNICODE data is stored in UTF-16/UCS-2 format. In UTF-16/UCS-2 format, all characters are two bytes long.
SAP DB is able to display various presentation codes in UNICODE format
<b>please close the thread after rewarding the appropriate points...</b>

Spooling file in Unicode format

I have some data in a table which I need to spool out to a text file. The output file should be in the unicode format instead of the default ANSI format.
I am not able to figure out how to do this. Can someone help here?
Thanks,
Mayank

Thanks for the reply. I thought there would be some option to specify the encoding either in the Spool command or the Select command, so didn't give the version and OS information.
The Oracle version is: 10.1.0.2.0
OS: Windows 2000 Server
This is the query I'm using right now:
SET TERMOUT ON
PROMPT Extracting <table name>
SET TERMOUT OFF
SPOOL <table name>.txt
SELECT Col1||'$$$$!@**'||Col2||'$$$$!@**###' FROM <table name>;
SPOOL OFF
This would create a text file with the same name as the table, only it would be in the ANSI encoding. What I need is to create the text file with Unicode encoding.
Is there a way to do this?
Thanks,
Mayank

Help,DataInputStream and Unicode encoding problem

Hello,everybody
I am writing a small software for fun,but an problem about Unicode encoding stopped me. I tried to parse a file including integers,floats and Unicode characters(not UTF-8 but some other encoding type). I looked for the JDK documentation and I found that the class DataInputStream( implementing the interface DataInput) fitted my requirement best, then I tried but the Unicode characters are not read correctly( messy codes,only '????????').
would you please help me? thanks a lot :-)

the class DataInputStream has the methods useful to me, but find there is no method to set the encoding format ,both in DataInputStream and argument types used in its constructor:
FileInputStream fis=new FileInputStream(fileName);
DataInputStream     dis=new DataInputStream(fis);
String line =dis.readLine();               System.out.println(line);
// only "????????" output as result :-(
I wonder how to set the encoding type,or another class.
if I do it this way,it works,but there is no methods such as "readFloat","readInt",etc, so it's not what I want :
FileInputStream fis=new FileInputStream(fileName);
InputStreamReader read=new InputStreamReader(fis,"GB2312");
BufferedReader reader=new BufferedReader(read);
DataInputStream     dis=new DataInputStream(fis);
String line = reader.readLine();
System.out.println(line);
thank you for your repley!

Converting from PDF directly to Java Objects/XML (and PDF format questions)

Hi,
I posted this originally in the Acrobat Windows forums but was told I might have more luck here, so here goes:
I am desperately trying to find a tool (preferably open source but commercial is fine also) that will sit on top of a PDF and allow me to query it's text for content and formatting (I don't care about images). I have found some tools that get me part of the way there, but nothing that seems to provide an end-to-end solution but is quite lightweight. My main question is WHY are there so many tools that go from PDF to RTF, and many tools that go from RTF to XML, but NONE that I can find that go PDF to XML.
To clarify, by formatting I simply mean whether a line/block of text is bold/italic, and its font size. I am not concerned with exact position on the page. The background is that I will be searching PDFs and assigning importance to whether text is a heading/bodytext etc. We already have a search tool in place so implementing a pure PDF search engine is not an option. I need a lightweight tool that simply allows me to either make calls directly to the PDF OR converts to XML which I can parse.
Some tools I have tried:
1) PDFBox (Java Library) - Allows the extraction of text content easily, but doesn't seem to have good support for formatting.
2) JPedal (Java Library) - Allows extraction of text content easily, and supports formatting IF XML structured data is in the PDF (not the case for my data).
3) Nitro PDF (Tool) + RTF to XML (script) - This works quite nicely and shows that PDF to XML is possible, but why do I have to use 2 tools? Also, these are not libraries I can integrate into my app.
4) iText (Java Library) - Seems great at creating PDFs but poor at extracting content.
I don't really expect someone to give me a perfect solution (although that would be nice!).
Instead, what I'd like to know is WHY tools support PDF to RTF/Word/whatever retaining formatting, and other tools support RTF to XML with the formatting information retained. What is it about PDF and RTF/Word that makes it feasible to convert that way, but not to XML. Also, as I found in 3) above, it is perfectly feasible to end up as XML from PDF, so why do no tools support this reliably!
Many thanks for any advice from PDF gurus.

XML doesn't mean anything - it's just a generic concept for structuring
information. You need a specific GRAMMAR of XML to mean anything. So what
grammar would you use? Something standard? Make up your own?
However, there are a number of commercial and open source products that can
convert PDF to various XML grammars - SVG, ABW, and various custom grammars.
But the other thing you need to understand is that most PDF files do not
have any structure associated with them (as you saw when using JPEDAL). As
such, any concepts of paragraphs/sections/tables/etc. Are WILD GUESSES by
the software in question.

Exporting report as PDF and CSV formats same time with out executing DB query twice

Post Author: cpriyanka
CA Forum: Exporting
I am using Crystal Report 9.0 version and Java.
I am getting "PrintOutputController" from "ReportClientDocument"
And then by calling export(ReportExportFormat.PDF) generating PDF format report.
Now I need to generate both PDF and CSV format files same time. How can it be done?
My understanding is when we call "export" it does the DB query execution and other functionality.
In that case, if I call "export" two times with two different formats, then DB query will be executed twice and that takes lot of time.
To avoid, is there a way I can all some API so DB query executed once, but I can export report in to multiple formats?
I appreciate your help.
Thanks.

Hello,
Are you using the "pull" or "push" method for your crystal reports? If you are using the "pull" method (the report itself executes the sql) then I believe there is no way around having the query execute twice since it is fired off each time you open and export the report.
If you use the "push" method, however, then you can just create the recordset/dataset and then set the datasouce once for the report.
Here's a broad overview of push and pull though the Crystal Report Viewer is used. The viewer may or may not be applicable in your case:

With Reports 10G can you customize you message and stop formatting?

Oracle, states to come here for answer. they said, OTN should be able to help.
If any one knows how this can be done can you please help me out?
thanks,
We were told this was fixed with 10G so we upgraded to 10G. We have a
report and we want it to execute if it's less than 10 records if not we want a
message to come up that the report needs to be scheduled.
Well we run the report and it displays exceeded record count but the format
still runs so no time saved on the web.
If the record count was exceeded we want to HALT the system and not go any
farther.
Now if we could modify the system message 1825 we would be o.k. But we don't
know if that is going to work. If we could change the message we would be
o.k. with that. that would mean changing the system codes though.
### How is the Report being called (Command line, URL or via Oracle Forms): ###
If false comes back in the beginning then we don't want any report formatting
to be done. Right now the format is done it seems but no data is displayed
because criteria isn't met.
So we dont wnat the formatting to be run when criteria isn't met. But for
some
reason it still runs and takes time.
See we have some reports on the web that can only be ran by date range right
now the clients can only run the reports for a 6 months range.. Well some
clients have a lot smaller record count. So we want to change the way the
reports are ran to a records count. If the count is large than said amount
then a message comes up that states the report has to be scheduled. If the
amount is under said amount then the report runs.
So at this time in the report we do a count then we move onto will the report
run or not if over the amount we want to abort the process but we don't want
the client to see the abort. We definately don't want the client to sit and
wait for the format to run when NO Data is to be returned.
### Error messages and error scenario: ###
So what we want is too see a message "Schedule the report count exceeded" and
NO formatting done. If under amount we want the report to run.
### Provide a detailed step-by-step description of your problem or question: ###
Or is there a way to customize the messages the client / users will see. And
no formatting time for no records returned.

21-SEP-04 15:38:39 GMT
Hi Darlene!!
As talked to you on phone, here are the steps for you to try.
The below has been run as a test case using emp table in scott schema of a database
1) create a summary coloumn say cs_1 in the data model.
2) point the function to count.
3) Point the source to what ever's count you want it to be pointed to(say empno of emp table of
scott schema)
4) create a user parameter say NO_ROWS
5) in its property palette make its data type number and initial value as 1
6) I had teh following query for my report:
select empno, ename from emp
where rownum <= :no_rows
This means that the report that will be generated will consist of a total no of NO_ROWS(that we
shall be specifying at run time). The before report trigger(mentioned in 7 below) shall assure
that whenever we specify NO_ROWS greater than 5 then the report will display a customized pop up
message.
7) create a before report trigger as:
function BeforeReport return boolean is
user_excp EXCEPTION;
begin
if :cs_1 >5 then
raise user_excp;
return (false);
else
return true;
end if;
EXCEPTION
WHEN user_excp then
SRW.MESSAGE(30, 'Data is more please schedule this report:');
raise SRW.PROGRAM_ABORT;
return (false);
end;
This way when u run a report, an argument is asked whether how many rows do you want to be
displayed as in the parameter NO_ROWS. then you specify the number. If that number is greater
than 5(in this case, due to if :cs_1 > 5 then....) then it will pop up a message saying "Data is
more please schedule this report:"
In case you do not want to specify NO_ROWS..then you need not put that and modify the report
query as "select empno, empname from emp;" i.e. without where clause.

I tried this step by step, but unfortunately, it doesn't work the way we want.
First with this suggestion, the user needs to choose how many records they
want
to get, or we default a number of records, in order to run the report. The most
important thing is, whenever you specify the statement return false or raise
SRW.PROGRAM_ABORT in the before report trigger, the system message will pop up.
I really hope that people from Oracle would let us know how to customize the
system message or hide it.

How can I embed files of word, excel, and pdf format in a pdf document

I have a word document of the product, which I am updating for next product release. However, there are some excel, word, and pdf files embedded within a word document. When I double click these embedded files in word, these files open in a new window. However, we deliver documentation to the customer in the pdf format. Therefore, when I am converting the word document in the pdf format, only an icon of the embedded file is displayed and the files do not open in a new window. Can someone let me know how can I embed these files (in word, excel, and pdf format) in a pdf document?

You must attach them to the PDF file after it is created. You cannot embed file attachments onto a page as you can with Word.

Combined Upgrade and Unicode conversion of Sap 4.6C to ECC6.0

Hello all,
my project team intends to carry out a combined upgrade and unicode conversion of an SAP ERP 4.6C system with MDMP to ECC6.0 (no enhancement package). The system is running on Oracle 10.2.
In preparation for this upgrade, I have gone through the SAP notes 928729, 54801.
We need to get a rough estimate of the entire downtime so as to alert our end users. From the CU&UC documentation in 928729, I read up note 857081. However the program in this note cannot be used to estimate the downtime as my system is < SAP netweaver 6.20.
Is there any other SAP note or tool or program that I can use to estimate the downtime for the entire CU&UC? Thanks a lot!

Hi,
Combined upgrade depend upon number of factors like database size, resources on the server and optimization. In order to get idea of how much downtime, it will take, I would suggest you to do combined upgrade and unicode conversion on sandbox system which should be the replica of your production system. And try to optimize it. From there you can get approx. downtime required.
Also, please read combined upgrade and unicode conversion guides on http://service.sap.com/unicode@sap
Thanks
