[iText-questions] tiff2pdf - pdf image does not match tiff
Hi,
We are trying to use iText Library for converting Fax TIFF images to
PDF. We are observing that with the following code snippet, the output
PDF page size matches the input TIFF page size but the image within the
PDF is shrunk by approx 1/4inch when compared to the input TIFF File.
For example if the input TIFF file was 8.47in x 9.1in with a X DPI=204
and Y DPI = 196 with a printed image of 6in x 7in then the output PDF
produced has a page size of 8.47in x 9.1in (so far good) but the printed
image is shrunk to 6in x 6.75 in.
What may be the possible reason for this shrinkage? How can this be
corrected?
Code snip
if(inputFileName != null inputFileName.length()!=0 ){^M
Document document = new Document(PageSize.LETTER);^M
FileOutputStream fop = null;^M
PdfWriter writer = null;^M
RandomAccessFileOrArray ra = null;^M
try {^M
int numOfPages = 0;^M
float heightInInches = 0;^M
float widthInInches = 0;^M
float xPoints = 0;^M
float yPoints = 0;^M
^M
fop = new FileOutputStream(outFileName);^M
writer = PdfWriter.getInstance(document,fop);^M
document.open();^M
PdfContentByte cb = writer.getDirectContent();^M
ra = new RandomAccessFileOrArray(inputFileName);^M
numOfPages = TiffImage.getNumberOfPages(ra);^M
for (int page = 0; page numOfPages; ++page) {^M
Image img = TiffImage.getTiffImage(ra, page + 1);^M
if (img != null) {^M
heightInInches =
img.getHeight()/img.getDpiY();^M
widthInInches = img.getWidth()/img.getDpiX();^M
//iText uses a 72 points per inch scale. ^M
xPoints = widthInInches*72;^M
yPoints = heightInInches*72;^M
document.setPageSize(new Rectangle(xPoints,
yPoints));^M
document.setMargins(0, 0, 0, 0);^M
document.newPage();^M
img.scaleToFit(xPoints,yPoints);^M
img.setAbsolutePosition(0,0);
^M
cb.addImage(img);^M
}^M
} ^M
Code snip
Thanks in advance

In your code, the first page size will always be LETTER.

Re: [iText-questions] tiff2pdf byte Array problem
Ok,
ByteArrayOutputStream baos =new ByteArrayOutputStream();
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document,baos);
try {
int pages = 0;
document.open();
PdfContentByte cb = writer.getDirectContent();
RandomAccessFileOrArray ra = null;
int comps = 0;
try {
ra = new
RandomAccessFileOrArray(tiff.getStream());
comps = TiffImage.getNumberOfPages(ra);
for (int c = 0; c comps; ++c) {
try {
Image img =
TiffImage.getTiffImage(ra,c+1);
long h = 0;
long w = 0;
if (img != null) {
Float height = new
Float(img.getScaledHeight());
h = height.longValue();
Float width = new
Float(img.getScaledWidth());
w = width.longValue();
float percent = 100;
int pos = 0;
if (w 895)
percent = ((595 + 18) *
100 / w);
if (h 842)
pos = (int) (842 - h *
percent / 100);
else
pos = (int) (842 - h);
img.scalePercent(percent);
img.setAbsolutePosition(0,pos);
document.add(new Paragraph());
cb.addImage(img);
document.newPage();
++pages;
}
} catch (Throwable e) {
e.printStackTrace();
}
}
} catch (Throwable e) {
e.printStackTrace();
}
FileOutputStream fos= new
FileOutputStream(result.pdf);
fos.write(baos.toByteArraY());
document.close();
}
the code for conversion is the same.
I must use a byte array because i want to return this to another method.

this code work fine.
but if i set PdfWriter writer = PdfWriter.getInstance(document,new

and then i write the content of outputstream on a file the pdf result is
corrupted...
Can anyone help me??

So much code and nothing useful to see. If your problem is with
ByteArrayOutputStream why don't you post the code that uses it?

[iText-questions] tiff2pdf problem
Hi, We have some tiff files which we convert to a pdf using the PhotoAlbum feature in iText 2.0.2 on a Windows XP box. The resultant pdf opens fine with Adobe Acrobat Reader . However when it is opened with either Adobe Acrobat or Adobe Distiller (various versions) and some pages are deleted manually an error window pops up saying to the efect Cannot read file error (16) . However, the same tiff files ALWAYS work, when converted into pdf using GNUwin32 libtiff using tiffcp and tiff2pdf exe's. Any suggestions are appreciated. Thanks Vikram ps: Note that the photoalbum-generated pdf doesn't ALWAYS fail.

[iText-questions] Tiff2Pdf
I've already posted on this subject but nobody answered because probably my question was not clear enough. I'm using tiff2pdf to create pdf from scanned tiff images. Imagescaling, rotation and positioning work fine and the final pdf is perfect. However I would like to timestamp it at creation time by using the DateTime and Software information that have been included in the tiff IFD by the scanner (but the DateTime could be enough too). My question is: is it possible to get this information directly with iText/Tiff2Pdf without pre-running a tiff read.

During tiff to pdf conversion is it possible to get tiff tags, like for example the DateTime Tag (Code 306 (hex 0x0132)), Software Tag, etc ?

Re: [iText-questions] tiff2pdf with jbig2
Hi Paulo,
yesterday the unreadable pdf had this:
2 0 obj /Filter/JBIG2Decode/Type/XObject/Length 21289/BitsPerComponent
1/Height 805306624
This morning I put the code into another system and now I get:
2 0 obj /Filter/JBIG2Decode/Type/XObject/Length 21289/BitsPerComponent
1/Height 1779
and Reader do OPEN it !!
Again, I want to thank you for your assistance.
Have a nice day.
Giuseppe.

[iText-questions] tiff2pdf with jbig2
At present on our iSeries(as400) we use iText/tiff2pdf to create pdf from scanned tiff documents. We produce thousands of documents per day and this works perfecty. However because these pdf's should be archived on optical disks and kept for one year (and because optical media cost a lot) we are intereted in reducing the final size of the document. We have been able to port leptionlib and jbig2 on our system and now we can get a output. and output.sym from a tiff image that is 35 to 60 % less that a tiff g4 image. Python script can generate a pdf from it, but we would prefer a java solution. Is there a way to implement iText to include this jbig2 compressed image instead of tiff ? Thanks.

[iText-questions] tiff2pdf and pdf2tiff
Hi,
we need to do both of these things. The tiff2pdf works for the most
part... just grabbed some sample code of the web site:
public void testTiff2PdfTest() {
//String tiffFile = rootDir+crl2688.tif;
String tiffFile = rootDir+400dpiCCITTGroup4.tif;
String pdfFile = rootDir+pdfer.pdf;
Document document = new Document();
try {
PdfWriter.getInstance(document, new FileOutputStream(pdfFile));
document.setMargins( 0f, 0f, 0f, 0f);
document.open();
Image tiff = Image.getInstance(tiffFile);
tiff.scalePercent(18);
document.add(tiff);
}
catch(DocumentException de) {
System.err.println(de.getMessage());
}
catch(IOException ioe) {
System.err.println(ioe.getMessage());
}
document.close();
}
The only problem is that it only grabs the first page of the tiff.
Does anyone know how I can grab the second page of the tiff?
Also, it seems it would be easy to go from pdf2tiff, but I can't seem
to grasp it. Is this possible with itext? If not, can someone refer
me to a good open source library that does?
Thanks,
Ben

Re: [iText-questions] tiff2pdf and pdf2tiff
actually I tried using the Tiff2Pdf tool:
public void testTiff2PdfTest() {
String tiffFile = rootDir+400dpiCCITTGroup4.tif;
String pdfFile = rootDir+pdfer.pdf;
Tiff2Pdf.main(new String[] {tiffFile, pdfFile});
}
This works, but the top margin is way too big and the filename is
being put at the top of the page (which makes is not acceptable for
us). Is there any way to control these things? I'll grab the source
and see how it's done.
Thanks,

Try the Tiff2Pdf tool in this JWS app: www.lowagie.com/iText/itext.jnlp
The code can be found in package com.lowagie.tools.plugins
Also, it seems it would be easy to go from pdf2tiff, but I can't seem

No, iText doesn't generate TIFF.

Yes, there is.
If you choose 'original' as pagesize in the JWS app,
the PDF pages have the same size as the TIFF pages.
Remark that you are probably looking at the 1.3 code.
For the JWS app, I am already using new code
(you'll find the complete javafile in the CVS repository):
for (int c = 0; c comps; ++c) {
Image img = TiffImage.getTiffImage(ra, c + 1);
if (img != null) {
if (adjustSize) {
document.setPageSize(new
Rectangle(img.scaledWidth(),
img.scaledHeight()));
document.newPage();
img.setAbsolutePosition(0, 0);
}
else {
if (img.scaledWidth() 500 ||
img.scaledHeight() 700) {
img.scaleToFit(500, 700);
}
img.setAbsolutePosition(20, 20);
document.newPage();
document.add(new Paragraph(tiff_file + - page
+ (c + 1)));
}
cb.addImage(img);
System.out.println(Finished page + (c + 1));
}
}
Create your Document with the size of the first page in the tiff.
Then change the pageSize for every new page BEFORE you
trigger a newPage().

Bruno
