Hello Tilman and others,
thanks for your answer.
I found a simple solution for this two errors (without handlers).
I include:
txtMark.setPrinted(true);
And exclude:
// txtMark.setConstantOpacity((float) 0.2); // 20% transparent
This is simple method for new annotation:
private void addPDAnnotationTextMarkup(List<PDAnnotation> annotations,
PDColor yellow, float ph) {
// Now add the markup annotation, a highlight to PDFBox text
PDAnnotationTextMarkup txtMark = new
PDAnnotationTextMarkup(PDAnnotationTextMarkup.SUB_TYPE_HIGHLIGHT);
txtMark.setPrinted(true);
txtMark.setColor(yellow);
// txtMark.setConstantOpacity((float) 0.2); // 20% transparent
//
// // Set the rectangle containing the markup
float textWidth = 7779 / 1000 * 18;
//logger.info("textWidth=[" + font.getStringWidth("Dodan nov tekst") + "]");
PDRectangle position = new PDRectangle();
position.setLowerLeftX(INCH);
position.setLowerLeftY(ph - INCH - 18);
position.setUpperRightX(INCH + textWidth);
position.setUpperRightY(ph - INCH);
txtMark.setRectangle(position);
//
// // work out the points forming the four corners of the annotations
// // set out in anti clockwise form (Completely wraps the text)
// // OK, the below doesn't match that description.
// // It's what acrobat 7 does and displays properly!
float[] quads = new float[8];
quads[0] = position.getLowerLeftX(); // x1
quads[1] = position.getUpperRightY() - 2; // y1
quads[2] = position.getUpperRightX(); // x2
quads[3] = quads[1]; // y2
quads[4] = quads[0]; // x3
quads[5] = position.getLowerLeftY() - 2; // y3
quads[6] = quads[2]; // x4
quads[7] = quads[5]; // y5
//
txtMark.setQuadPoints(quads);
txtMark.setContents("A simple comment");
annotations.add(txtMark);
}
It's working with PDF/A 2b and PDF/A 3b. And sign is not corupted.
Best regards
Anze
