Hi,
Thanks for the reply. I am using itext 5.5.3. and below is the sample code
void convertTiffToPDF (*final* PdfContentByte oContentBytes, *final*
P8Document oCEDocument, int nEndPage, int nStartPage)
RandomAccessFileOrArray oPage = *null*;
*int* nTiffPageToRead = 0;
*int* nContentElement = 1;
// make sure we don't try to read more than we have
*int* nLoopEnd = nEndPage;
// single content element, write all pages
oPage = *getContentElement*(oCEDocument, 1);
nLoopEnd = TiffImage.*getNumberOfPages*(oPage);
*int* nOutputPage = 0;
*for* (*int* i = nStartPage; i <= nLoopEnd; i++)
{
nOutputPage +=1;
// Read the page content from CE and determine which *tiff* page to get
*if* (nContentCount > 1)
{
// multiple contents elements each a single page
*tiff*
nContentElement = i;
nTiffPageToRead = 1;
oPage = *getContentElement*(oCEDocument, i);
}
*else*
{
// *multipage* *tiff* in a single content element
nContentElement = 1;
nTiffPageToRead = i;
*if* (i == nStartPage && oPage==*null*)
{
oPage = *getContentElement*(oCEDocument, 1);
}
}
*try*
{
// Get the image content from the page
*if* (nTiffPageToRead<=TiffImage.*getNumberOfPages*(oPage))
{
*final* Image oPageImage = TiffImage.*getTiffImage*(oPage,
nTiffPageToRead);
//set the global seek value to 0 for the next page
//otherwise it may cause EOFFileException while converting subsequent pages
oPage.seek(0);
// Adjust the page size to the image dimensions. Each content
// element can have its own dimensions
// the default for the PDF is 72 *dpi*, so adjust for *whats* in the
*tiff*
*float* width = *getOutputWidth*(oPageImage);
*float* height = *getOutputHeight*(oPageImage);
oDocument.setPageSize(*new* Rectangle(width, height));
// Create a new page
oDocument.newPage();
// Position the image at the upper left corner since the page
// has been sized to the image
oPageImage.scaleAbsolute(width, height);
oPageImage.setAbsolutePosition(0,0);
// Add the image to the page9
oContentBytes.addImage(oPageImage);
}
* private* *static* *float* getOutputWidth(Image oPageImage)
{
// a *jpg* with a DPI of 100 in viewer is reporting 1 in iText
//*int* OriginalType = oPageImage.getOriginalType();
//float *nheight* = oPageImage.getPlainHeight();
*int* dpi = oPageImage.getDpiX() == 1 ? 100 : oPageImage.getDpiX();
*return* dpi > 0 ? (oPageImage.getScaledWidth() * 72.0f)/ dpi :
oPageImage.getScaledWidth();
}
*private* *static* *float* getOutputHeight(Image oPageImage)
{
// a *jpg* with a DPI of 100 in viewer is reporting 1 in iText
*int* dpi = oPageImage.getDpiY() == 1 ? 100 : oPageImage.getDpiY();
*return* oPageImage.getDpiY() > 0 ? (oPageImage.getScaledHeight() * 72.0f)/
dpi : oPageImage.getScaledHeight();
}
I am not able to share any of the tiff but those are scanned document.
Thanks,
