Hi All!
Has anybody figured out how to embed an attachment data and make an Image
thumbnail to launch an appropriate viewer application? For example embed
Word file and make it open Word on a click on the image thumbnail thing?
Same for Excel or plain text file as well as images.
For now I have resorted to using a Url based anchor on the Chunk object, but
that is not what I need
since I need to make all the data be contained inside the pdf rather than
refer clicks to the server.
I tried several things, but nothing worked, please see a sample code below:
Any help is greatly appreciated.
-Vick
private Chunk createAttachmentChunk(PdfWriter docWriter, MediaBase att,
String type) {
URL url = new URL("${grailsApplication.config.baseUrl}" + type +
"/downloadByName/${att.id}_${att.fileName}");
byte[] b = loadBytesFromURL(url);
//PdfFileSpecification pdfSpec =
// PdfFileSpecification.fileEmbedded(docWriter, att.fileName,
att.title, b, true);
//docWriter.addFileAttachment(pdfSpec);
Image imageAttachment = Image.getInstance(new
URL("${grailsApplication.config.baseUrl}images/icons/attachment.png"));
imageAttachment.scaleToFit(40, 40);
imageAttachment.setAlignment(1);
//PdfAction action = PdfAction.gotoEmbedded(att.fileName, pdfSpec, "",
true);
//imageAttachment.setAdditional(pdfSpec);
//imageAttachment.setOriginalData(b);
//PdfAnnotation annot = PdfAnnotation.createFileAttachment(docWriter,
new Rectangle(0,0,0,0),
// att.fileName, b, "", att.title);
//imageAttachment.setAnnotation(annot);
Chunk ck = new Chunk(imageAttachment, 0, -5);
//chunk.setAction(action);
ck.setAnchor(url);
return ck;
}
