Hi,
I have a problem.
I am converting a TIF_G4 format file to pdf but the convetrted pdf displaying
the blank pages.
Can u help me in this?
Here is the code...
private void readTiffs(Object[] fileNames, String imageFileName, String
mergeLocation) throws IOException
{
java.io.File file = null;
SeekableStream ss = null;
ImageDecoder decoder = null;
Vector tiles = new Vector();
BufferedImage firstImage = null;
boolean assignFirstImage = true;
Raster rstr = null;
DataBuffer dataBuffer = null;
try {
// creation of the different writers
Document document = new Document(PageSize.A4, 50, 50, 50, 50);
PdfWriter writer = PdfWriter.getInstance(document,
new FileOutputStream(imageFileName+".pdf"));
writer.setFullCompression();
document.open();
PdfContentByte cb = writer.getDirectContent();
for (int j = 0; j < fileNames.length; j++)
{
file = new java.io.File(strStorePath +
java.io.File.separator + fileNames[j].toString());
if(!file.exists()){
errorLog.write(" while merging == " + file +"not
found");
System.out.println("while merging == " + file +"not
found");
continue;
}
File ch = new
File(imageFileName+fileNames[j].toString()+".tif");
file.renameTo(ch);
// PlanarImage img2 = JAI.create("fileload",
strStorePath + java.io.File.separator + fileNames[j].toString());
PlanarImage img2 = JAI.create("fileload",
imageFileName+fileNames[j].toString()+".tif");
//Image img = (Image)JAI.create("fileload",
strStorePath + java.io.File.separator + fileNames[j].toString());
//start pdf
// creation of the document with a certain size and
certain margins
//Document.compress = false;
//File file = new File("D:/test.txt");
//SeekableStream s = new FileSeekableStream(file);
//TIFFDecodeParam param = null;
//param = new TIFFDecodeParam();
// ImageDecoder dec =
ImageCodec.createImageDecoder("tiff", s, param);
//System.out.println("dec: " + dec);
// System.out.println("Number of images in this
TIFF: " + dec.getNumPages());
// Which of the multiple images in the TIFF file do
we want to load
// 0 refers to the first, 1 to the second and so on.
//int total = dec.getNumPages();
//for (int k = 0; k < total; ++k) {
//RenderedImage ri =
dec.decodeAsRenderedImage(k);
// System.out.println("ri: " + ri);
Raster ra = img2.getData();
BufferedImage bi = new
BufferedImage(img2.getColorModel(),
Raster.createWritableRaster(img2.getSampleModel(), ra.getDataBuffer(), null),
false, new Hashtable());
// System.out.println("bi: " + bi);
Image img = Image.getInstance(bi, null, true);
System.out.println("img: " + img);
//img.scalePercent(72f / 200f * 100);
//img.setAbsolutePosition(0, 0);
img.scalePercent(36F);
img.setAbsolutePosition(0.0F, 0.0F);
//System.out.println("Image: " + k);
cb.addImage(img);
System.out.println("cb: " + cb);
System.out.println("document: " + document);
document.newPage();
System.out.println("document: " + document);
//}
//end of pdf
/*ss = new FileSeekableStream(file);
decoder = ImageCodec.createImageDecoder("tiff", ss,
null);
int numPages = decoder.getNumPages();
for (int i = 0; i < numPages; i++)
{
rstr = decoder.decodeAsRaster(i);
dataBuffer = rstr.getDataBuffer();
PlanarImage rfmtImage = reformatImage(img,
new Dimension(rstr.getWidth(), rstr.getHeight()));
SampleModel sampleModel =
rfmtImage.getSampleModel();
ColorModel colorModel =
rfmtImage.getColorModel();
WritableRaster wr =
Raster.createWritableRaster(sampleModel, dataBuffer, new Point(0, 0));
BufferedImage bi = new BufferedImage(colorModel,
wr, colorModel.isAlphaPremultiplied(), null);
if (assignFirstImage)
{
firstImage = bi;
assignFirstImage = false;
}
else
tiles.addElement(bi);
}*/
}
document.close();
}
catch (Exception de) {
de.printStackTrace();
//System.err.println(de.getMessage());
}
try
{
//String tiffFile = saveAsMultipageTIFF(tiles,
firstImage, imageFileName);
}
catch (Exception e)
{
errorLog.write(" while merging == " + e);
e.printStackTrace();
}
}
thanks & regards
