Hi Joe,
I'm not absolutely sure, but I think it's maybe a similar problem like one
I had some time ago. Please check the dpi x and y values for TIFFs that
work and ones that don't work. If the dpi values for x and y axis are
different, you have to respect that while scaling the image. I use
Irfanview for checking the dpi values.
Best Regards
Benjamin

[iText-questions] Problem using iText to Convert from TIFF
Hi,
I'm a newbie in iText. I was trying to adapt the code given in the iText
tutorial in order to write a utility in Java to convert from TIFF to PDF
format.
The problem is that with certain TIFF files, the converted PDF is shrunk
and squeezed to the bottom of the page; it's hard to explain without an
image, but if you want to imagine it, the output seems as if someone had
pushed the text and graphics down with their hand, so the result is
compressed and covers only the bottom third of the page; the top
two-thirds are blank. I tried to play with the Image.scaleToFit(width,
height) and Image.setAbsolutePosition(x, y) methods, using a wide range of
values, but either there was no change at all, or the content was
partially displayed, as if I needed a lager page size. Should I try to
enlarge the page boundaries? If so I would appreciate it if you could
point me in the direction of the API to use.
I'm including a code snippet below (from the tutorial at
http://itextdocs.lowagie.com/tutorial/objects/images/tiff/index.php -->
the code is from Tiff2Pdf.java).
Thank you in advance for any help.
...
int pages = 0;
document.open();
PdfContentByte cb = writer.getDirectContent();
int comps = 0;
try {
ra = new RandomAccessFileOrArray(tiff_file);
comps = TiffImage.getNumberOfPages(ra);
}
catch (Throwable e) {...}
for (int c = 0; c < comps; ++c) {
try {
Image img = TiffImage.getTiffImage(ra, c + 1);
if (img != null) {
if (img.scaledWidth() > 500 || img.scaledHeight() > 700) {
img.scaleToFit(500, 700);
}
img.setAbsolutePosition(20, 20);
cb.addImage(img);
document.newPage();
++pages;
}
catch...
}
