--------------------------------------
Resolution: Duplicate
Assignee: Andreas Lehmkühler
> PrintImageLocations doesn't print images inside PDXObjectForm objects
> ---------------------------------------------------------------------
>
> Key: PDFBOX-1203
> URL: https://issues.apache.org/jira/browse/PDFBOX-1203
> Project: PDFBox
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 1.6.0
> Reporter: Ilija Pavlic
> Assignee: Andreas Lehmkühler
> Priority: Minor
> Original Estimate: 2h
> Remaining Estimate: 2h

> Some pdf store images inside forms to reuse them throughout the document.
> PrintImageLocations misses such images.
> A workaround that works for some documents:
> if (xobject instanceof PDXObjectForm) {
> Map images = ((PDXObjectForm)
> xobject).getResources()
> .getImages();
> if (images != null) {
> Iterator imageIter =
> images.keySet().iterator();
> while (imageIter.hasNext()) {
> String key = (String)
> imageIter.next();
> PDXObjectImage image =
> (PDXObjectImage) images.get(key);
> String name = key;
> //System.out.println("Writing
> image:" + name);
> //image.write2file(name);
> try {
> PDPage page =
> getCurrentPage();
> Matrix ctm =
> getGraphicsState()
>
> .getCurrentTransformationMatrix();
> double
> rotationInRadians = (page.findRotation() * Math.PI) / 180;
> AffineTransform
> rotation = new AffineTransform();
>
> rotation.setToRotation(rotationInRadians);
> AffineTransform
> rotationInverse = rotation.createInverse();
> Matrix
> rotationInverseMatrix = new Matrix();
> rotationInverseMatrix
>
> .setFromAffineTransform(rotationInverse);
> Matrix rotationMatrix =
> new Matrix();
>
> rotationMatrix.setFromAffineTransform(rotation);
> Matrix unrotatedCTM =
> ctm.multiply(rotationInverseMatrix);
> float xScale =
> unrotatedCTM.getXScale();
> float yScale =
> unrotatedCTM.getYScale();
>
> imagesInformation.add(new ImageInformation(name, unrotatedCTM.getXPosition(),
> unrotatedCTM.getYPosition(), xScale / 100f * image.getWidth(), yScale / 100f
> * image.getHeight()));
> } catch
> (NoninvertibleTransformException e) {
