Will Rayer,
Can you try following code its work.
Inside the For loop u can get all the time new RandomAccessFileOrArray its
works.
// Loop through all the pages in the TIFF file, convert each to
PDF.
for (int c = 0; c < comps; ++c) {
try {
* ** RandomAccessFileOrArray raNew = null;*
* raNew = new RandomAccessFileOrArray(fis);*
Image img = TiffImage.getTiffImage(raNew , c
+ 1);
if (img != null) {
if (img.getScaledWidth() > 500 ||
img.getScaledHeight() > 700) {
img.scaleToFit(500,
700);
}
img.setAbsolutePosition(20, 20);
//document.add(new Paragraph(tiff_file +
" - page " + (c + 1)));
cb.addImage(img);
document.newPage();
++pages;
}
}
catch (Throwable e) {
throw new PRRuntimeException("Exception " +
tiff_file + " page " + (c + 1) + " " + e.getMessage());
}
}
// Close the TIFF file and the PDF file.
ra.close();
document.close();
}
