Hi Tilman
My bad, I was working on the image code and just assumed that it was the
culprit.
It turns out that I must be embedding fonts incorrectly. I use this code
each time I open the PDF:
var resources = Objects.requireNonNullElseGet(
pdForm.getDefaultResources(), PDResources::new );
var lucidaFont = PDType0Font.load( pdfDoc, LUCIDA_UNICODE_FILE.get() );
var cosName = COSName.getPDFName( lucidaFont.getName() );
resources.put( cosName, lucidaFont );
pdForm.setDefaultResources( resources );
The above seems to make the PDF get bigger each time it's opened and then
saved.
So I've added a check first, like this:
if ( resources.getFont( cosName ) == null )
{
resources.put( cosName, lucidaFont );
pdForm.setDefaultResources( resources );
}
And now the PDF doesn't seem to be growing any more.
Thanks,
Jurgen

Do you save directly or incrementally?
If directly then the old one should be gone. If not, please share the
PDF (upload to sharehoster) and tell us why you think it's still there.

Hi
I would like to know how to remove an image resource from a PDF form.
I use the following code to set an image object on a field:
private static void setAppearance( PDDocument pdfDoc, PDField
field, PDImageXObject image )
{
var widget = field.getWidgets().get(0);
var rect = widget.getRectangle();
var formObj = new PDFormXObject( new PDStream( pdfDoc ) );
formObj.setResources( new PDResources() );
formObj.setBBox( new PDRectangle
(
// The TransformationMatrix below enlarges the image
slightly,
// so adjust accordingly here otherwise the image is
cropped.
rect.getLowerLeftX(), rect.getLowerLeftY() - 10,
rect.getWidth(), rect.getHeight() + 20
));
formObj.setFormType(1);
var appearanceStream = new PDAppearanceStream(
formObj.getCOSObject() );
var pageContentStream = new PDPageContentStream( pdfDoc,
appearanceStream );
pageContentStream.drawImage( image, getTransformationMatrix(
image, widget ) );
pageContentStream.close();
var appearance = new PDAppearanceDictionary();
appearance.setNormalAppearance( appearanceStream );
appearance.getCOSObject().setDirect( true );
widget.setAppearance( appearance );
}
To remove the image I do "widget.setAppearance( null )" or to replace
the image I use the above method to set the new image as the
appearance. However I've noticed that this doesn't remove the previous
image object/resource from the PDF. How do I go about removing it ?
Thanks, regards
Jurgen
