There are already many useful ways to obtain and compose URLs in the 
core Java API.  For example, if you are getting your image from a 
file, you can construct a File object representing your base path, 
and then use the File(File, String) constructor to obtain various 
relative paths off that.  File has a handy toURL() method that will 
get you the URL you need.  Similarly, you can construct a base URL 
class and then construct relative paths from it.  Finally, consider 
the Class.getResource(String) method (which returns an URL) as a 
great way to locate image files in a portable manner that will not 
need to change regardless of whether your image in an a file system, 
packed into a JAR file, or even being fetched across the network. 
Consult the core API Javadoc for more information.

Re: [iText-questions] How to specify link with japanese chars.

2002-05-01 Thread Kumata Mitsugu 

Hello all,

I'm a Japanese iText user.
I will be glad if the follwings are a clue as to the solution of the problem
of Japanese chars.

I do not know if iText will produce PdfString object represented by
hexadecimal strings which must be enclosed within angle brackets < and >.
So, I tried to make a change to a line in a pdf source which is generated by
iText.
Changed result is as follows:

  /F <8341 2f 8343 2e 70 64 66>

Spaces in angle brackets are meaningless for PDF Viewer. I put them just for
making it easy to visually recognize each characters. So, even if there are
no spaces, you can get the same result.

Codes in angle brackets are Shift-JIS code which is a major encoding for
Japanese characters.

"<8341 2f 8343 2e 70 64 66>" represents a relative path.

Each Shift-JIS code represents as follows;
 
 8341 -> Japanese Katakana "a" (30a2 in Unicode)
 2f ---> slash (represents directory)
 8343 -> Japanese Katakana "i" (30a4 in Unicode)
 2e ---> period
 70 ---> p
 64 ---> d
 66 ---> f

This link will work both on Japanese Winodews and Japanese Mac OS with
Japanese Acrobat.

Regards,
KuMi

[iText-questions] (no subject)

2002-05-01 Thread Ramakrishna Kuppa 





I am receiving this error message when trying to dynamically create and display a PDF document:


"com.lowagie.text.DocumentException: banner-3part1.gif is not a supported GIF-file (the image separator '0x2c' is not found after reading the color table)

    at com.lowagie.text.pdf.PdfDocument.add(Unknown Source)
    at com.lowagie.text.Document.add(Unknown Source)"


I would like to know of any tool / package using which I can check, and modify if necessary, my images.


Thanks

[iText-questions] iText design question

2002-05-01 Thread Leonard Rosenthol 

I have two questions about the low level design decisions make during 
the coding of iText.

1) Why the are two different types of low level PDF objects? 
PRObject vs. PDFObject, etc.

2) Why are both these sets of objects private to their package, 
thereby disallowing "low level" access to applications?


I ask these as I am in the process of extending the reading, parsing 
and manipulating capabilities of the library - but these particular 
restrictions are a major roadblock, since it prevents object-level 
access to the application.

And if there isn't any good reason - would one of the maintainers be 
willing to commit the changes to make these objects public?


Thanks in advance,
Leonard

[iText-questions] Inserting images dynamically ...

2002-05-01 Thread Ramakrishna Kuppa 
Title: Inserting images dynamically ...





Hi


I am creating a PDF report dynamically. I have some images which need to be inserted into the document. I am trying to use the Gif class to load the image; however, it needs a URL to the image. How can I specify this during development and distributed deployment?

Having gone thru' the HELP docs. and the API, I felt that the Image API should be expanded to take in the document root and a relative path and return a suitable instance.

Thanks

[iText-questions] Acrobat 5 vs. Acrobat 4 problem

2002-05-01 Thread Wilhelm *Rafial* Fitzpatrick 

I am using iText to create PDF's of filled out forms by opening a 
single page PDF document, copying the page into a new document, and 
adding text to fill out the form fields.  Sometimes the resulting PDF 
has multiple pages, each made by copying the single page template 
over and over again, then adding text.

So far this has worked great.  However, I have discovered that with 
some (not all) of the PDFs I am using a templates, the follow problem 
occurs:

When the output document is viewed in Acrobat Reader 5, the added 
text on the last page is not displayed.  If the document is a single 
page, none of the added text is displayed.  The same documents work 
fine when displayed in Acrobat Reader 4 or xpdf.

Has anyone ever seen a problem like this?  Any suggestions as to what 
might be causing it?

Thanks for any insight!

Re: [iText-questions] hiding a form field by default

2002-05-01 Thread Paulo Soares 

If I understand your question you want the initial state of the field to be
hidden. Use the flag PdfAnnotation.FLAGS_HIDDEN.

Paulo Soares

It looks like postscript doesn't like empty text objects. Next version will
have this fixed.
