Open PDF in Safari with image annotation
Hello,
I am using PDFBox to add an image as an annotation into a PDF.
When I open the PDF into Safari (macOS) the width of the image is reduced
(the image does not look like it should be)
[image: LoremIpsum_Test_simple_2_pages-testA_pdf.png]
This is the PDF :
https://drive.google.com/file/d/1lP6v90nEAQWuY84t1S0L8BWZkbiZ0mUw/view?usp=sharing
This is the original image :
https://drive.google.com/file/d/1X-dtqisuXLOkwBq1MvZueC69wdxhO8QH/view?usp=sharing
I apply a reducing zoom on the image.
Do you have any idea where my mistake is ? (annotation name :
73d51ba49022499ca1315b530f194276).
If I open the PDF into chrome,... acrobat, everything is fine (which does
not means my code is fine :D, may be these viewer are catching my mistake)
I simplified my method but this is the code (because I manage other use
cases...):
private static void addAnnotationStamp(final PDDocument doc,
AnnotationObject annotationObject) throws IOException {
PDPage page;
int nbPages = doc.getNumberOfPages();
int pageNumber = 0;
if (annotationObject.getPage() != null) {
pageNumber = annotationObject.getPage();
nbPages = 1;
}
while (nbPages > 0) {
page = doc.getPage(pageNumber);
float pw = page.getMediaBox().getUpperRightX();
float ph = page.getMediaBox().getUpperRightY();
logger.debug("Page(" + pageNumber + ") - size : " + pw + " x " + ph);
List<PDAnnotation> annotations = page.getAnnotations();
PDAnnotationRubberStamp stamp = new PDAnnotationRubberStamp();
//Name is important and should be unique
if (annotationObject.getPage() != null)
stamp.setAnnotationName(annotationObject.getName());
else
stamp.setAnnotationName(annotationObject.getName() + "-" + pageNumber);
logger.debug("Annotation : " + stamp.getAnnotationName());
stamp.setPrinted(true); // always visible
stamp.setReadOnly(true); // does not interact with user
stamp.setLocked(true);
stamp.setLockedContents(true);
//Stackoverflow
https://stackoverflow.com/questions/74836898/pdfbox2-acrobat-consider-my-annotation-added-between-two-signature-as-modified
stamp.setPage(page);
float objectWidth;
float objectHeight;
int heightTranslate = 1;
PDImageXObject image = null;
image = PDImageXObject.createFromFile(annotationObject.getImgSrc(), doc);
objectWidth = image.getWidth() * annotationObject.getImgZoom() / 100;
objectHeight = image.getHeight() * annotationObject.getImgZoom() / 100;
heightTranslate = 5;
logger.debug("Image size: " + objectWidth + " x " + objectHeight + " zoom
is " + annotationObject.getImgZoom());
PDRectangle rect = new PDRectangle(annotationObject.getX(), ph -
annotationObject.getY() - heightTranslate - objectHeight, objectWidth,
objectHeight);
stamp.setRectangle(rect);
PDAppearanceStream appearanceStream = new PDAppearanceStream(doc);
appearanceStream.setBBox(new PDRectangle(1, 1));
appearanceStream.setResources(new PDResources());
try (PDPageContentStream contentStream = new PDPageContentStream(doc,
appearanceStream)) {
contentStream.drawImage(image, new Matrix());
}
PDAppearanceDictionary appearance = new PDAppearanceDictionary();
appearance.setNormalAppearance(appearanceStream);
stamp.setAppearance(appearance);
stamp.setIntent(PDAnnotationRubberStamp.IT_FREE_TEXT);
annotations.add(stamp);
page.setAnnotations(annotations);
// these must be set for incremental save to work properly (PDFBOX < 3.0.0
at least?)
//ap.getCOSObject().setNeedToBeUpdated(true);
stamp.getCOSObject().setNeedToBeUpdated(true);
page.getResources().getCOSObject().setNeedToBeUpdated(true);
page.getCOSObject().setNeedToBeUpdated(true);
doc.getDocumentCatalog().getPages().getCOSObject().setNeedToBeUpdated(true);
doc.getDocumentCatalog().getCOSObject().setNeedToBeUpdated(true);
nbPages--;
pageNumber++;
}
}
Best regards,
Fred

Posted by Frédéric Ravetier <fr...@vikta.com>.
I found the problem,
.setBBox(new PDRectangle(objectWidth, objectHeight));
and
.drawImage(image, 0, 0, objectWidth, objectHeight);

Re: Open PDF in Safari with image annotation
Posted by Tilman Hausherr <TH...@t-online.de>.
I don't see any problem, but I never created a form object from scratch.
The PDRectangle(1,1) looks unusual but might still work, I remember that
there is some math when forms are rendered.
Your image isn't displayed, it's probably a non-inline attachment. I
don't have Safari.
A solution would be to create and modify your annotation with Adobe
until it works with Safari, and then use PDFDebugger to compare with
your own.
