Optimize PDF and resize content to fit A4

Aspose.PDF Product Family
1

I have code like this

Document pdfDocument = new Document(“input.pdf”);
for (Page page : pdfDocument.getPages()) {
	double originalWidth = page.getPageRect(false).getWidth();
	double originalHeight = page.getPageRect(false).getHeight();

	// Skip scaling and just crop if either dimension is 0.
	if (originalWidth == 0 || originalHeight == 0) {
		continue;
	}

	double targetWidth = PageSize.getA4().getWidth();
	double targetHeight = PageSize.getA4().getHeight();

	// Only scale as much as necessary. Maintain aspect ratio.
	double widthScale = (originalWidth<originalHeight? targetWidth: targetHeight) / originalWidth;
	double heightScale = (originalWidth<originalHeight? targetHeight: targetWidth) / originalHeight;

	double scale = 1.0d;
	if (widthScale <= heightScale) {
		scale = widthScale;
	} else {
		scale = heightScale;
	}

	//nicht vergrößern
	if (scale > 1) continue;

	//Minimale Abweichungen zulassen
	if (scale > 0.90) continue;

	double destWidth = originalWidth * scale;
	double destHeight = originalHeight * scale;
			
	PdfFileEditor.ContentsResizeParameters par = PdfFileEditor.ContentsResizeParameters.pageResize(destWidth, destHeight);
			
	com.aspose.pdf.facades.PdfFileEditor pfe = new com.aspose.pdf.facades.PdfFileEditor();
	pfe.resizeContents(pdfDocument, new int[] {page.getNumber()}, par);
}

// Save output as PDF format
pdfDocument.save("output.pdf");

It works as expected for most files. But with one pdf svg_00808043_S_1_B-Plan_GolfparkWeiherhof_Erweiterung.pdf (1.6 MB) the Content is shifted outside the pdf page. Could you please give me a hint, what is going wrong. I think it has to do with the CropBox of the input.pdf.

Thanks
