JPedal Image Thumbnail
Sample Code:
import
java.awt.image.BufferedImage;
import java.io.FileOutputStream;
import
java.io.IOException;
import org.jpedal.PdfDecoder;
import
com.sun.image.codec.jpeg.JPEGCodec;
import
com.sun.image.codec.jpeg.JPEGEncodeParam;
import
com.sun.image.codec.jpeg.JPEGImageEncoder;
public class PdfToImage {
public PdfToImage() {
}
/**
* @param args
*/
public static void main(String[] args)
{
try{
PdfDecoder decode_pdf = new
PdfDecoder(true);
// your font dir
here
String yourFontDirectory =
"c:/webdocx/lib/fonts";
decode_pdf.setTTFontDirs(new
String[]{yourFontDirectory});
decode_pdf.useHiResScreenDisplay(true);
String
pdfToDecode = "c:/maureen bonfiglio
3-1-06.pdf";
decode_pdf.openPdfFile(pdfToDecode);
int
imageHeight = 1056;
int pageFromPDF =
1;
BufferedImage image_to_save =
decode_pdf.getPageAsThumbnail(pageFromPDF,
imageHeight);
System.out.println(image_to_save);
saveImage(image_to_save,
.9f, "c:/test2.jpg");
}
catch(Exception
e){
e.printStackTrace();
}
new
PdfToImage();
}
public static void
saveImage(BufferedImage image, float quality, String
fileName){
try{
FileOutputStream fos =
null;
fos
= new FileOutputStream(fileName);
JPEGImageEncoder
encoder =
JPEGCodec.createJPEGEncoder(fos);
JPEGEncodeParam param = JPEGCodec.getDefaultJPEGEncodeParam(image);
param.setQuality(quality,
true);
encoder.encode(image, param);
fos.flush();
fos.close();
}
catch(IOException
ioe){
ioe.printStackTrace();
}
}
}
Any Problems, let me
know

I should've mentioned...I have to create them as
JPEG's...do you see any issue with getting the "good quality" images you got
with PNG....even "close"?
Thanks again,

Hey Bill, I realize this is a month later
(sorry!)...
Quick questions for you:
1) Were you using the OS version of JPedal or
which version?
2) Can you share some snippet of
code/class/methods that I can try to create some (fairly big) thumbnails of
some PDFs? (I think this was either a topic of this thread, or very
related...) I need to create like a 400x500 thumbnail (call it a GIANT
Thumbnail!) of the first page of each of my PDFs.
Any ideas, thoughts, code you can
share???
Thanks in advance!
-Aaron

Hello All!
Yesterday I
helped someone figure out how to get images from a PDF using JPedal and
not turn out grainy.
After
doing that I stuck around in JPedal and did some playing and found a neat
trick that I wanted to pass on To this Mail
Group.
As you
know, JPedal can create a fairly passable preview image of a PDF, but with
a little fiddling with the PdfDecoder class
I was able
to add a method that will take any Graphics2D object and paint to
it. I passed in a iText PdfGraphics2D Object and
was
pleasantly surprised how well the final PDF turned out.
Using
Batik, I was also able to pass an SVGGraphics2D Object and
convert a PDF into and SVG
file.
I realize
this has almost no relevance to iText, but I thought it was neat and
wanted to share it.
If anyone
want's the modified PdfDecoder for JPedal, I will happily send it
along.
