Hi,
hope you can help me fixing the following unreasonable behavior:
situation:
my code uses a pdf file with embedded text, images and forms as a template
everything works the code searches the pdf for forms on different pages and the
forms are filled as defined
even pages with a form and image painting work, the forms prepared to
overwritten by an image show the new image
the problem:
when I paint an image on a pdfpage where a image already exists
in the template pdf the image from the template get’s invisible
I checked the coordinates of the the painting – ok the new
image is on the right position
the relevant code:
for (String imagename : this.templateimages.keySet()) {
PDField field2 = (PDTextField)
acroForm.getField(imagename);
if (field2 != null) {
field2.setValue(" ");
field2.setReadOnly(true);
COSDictionary fieldDict =
field2.getCOSObject();
COSArray fieldAreaArray = (COSArray)
fieldDict.getDictionaryObject(COSName.RECT);
PDRectangle result = new
PDRectangle(fieldAreaArray);
int fieldpagenumber =
getFormPagenr(field2);
if (fieldpagenumber >= 0 && result !=
null) {
PDPage page =
doc.getPage(fieldpagenumber);
FileObject file =
this.templateimages.get(imagename);
if (file != null &&
file.exists() == true)
{
InputStream is =
file.getContent().getInputStream();
BufferedImage awtImage =
ImageIO.read( is );
PDImageXObject pdImage =
LosslessFactory.createFromImage(doc, awtImage);
PDPageContentStream
contents = new PDPageContentStream(doc, page);
log.info("drawimage x={}
y={} w={} h={}",result.getLowerLeftX(), result.getLowerLeftY(),
result.getWidth(), result.getHeight());
contents.drawImage(pdImage, result.getLowerLeftX(), result.getLowerLeftY(),
result.getWidth(), result.getHeight());
contents.close();
} else {
log.error("problem at pdf
generate pdimage file=null or file does not exist {}"
+ ((file !=
null) ? file.getPublicURIString() : ""));
throw new Exception("file
not found "+file);
}
} else {
log.error("probelm at pdf
generate pagenumber<0 or result=null");
throw new Exception("template
has no pages");
}
} else {
throw new Exception("field for image "
+ imagename + " not found");
}
}
