I have tried multiple ways to rotate the content of a page using
5.1.3, but nothing seems to be working for me. I either get a blank
page, or no difference.
current working code:
com.itextpdf.text.pdf.PdfDictionary pageDict =
reader.getPageN( pageNum );
com.itextpdf.text.pdf.PdfNumber pageRot =
pageDict.getAsNumber( com.itextpdf.text.pdf.PdfName.ROTATE );
log.trace( "Rotation: " + pageRot );
currentPageNumber++;
if( getSizeWithRotation )
{
document.setPageSize(
reader.getPageSizeWithRotation( pageNum ) );
}
document.newPage();
com.itextpdf.text.pdf.PdfImportedPage page =
writer.getImportedPage( reader, pageNum );
cb.addTemplate( page, 0, 0 );
if( footer )
{
cb.beginText();
cb.setFontAndSize( bf, 9 );
cb.showTextAligned(
com.itextpdf.text.pdf.PdfContentByte.ALIGN_CENTER, "Page: " +
currentPageNumber, 520, 5, 0);
cb.endText();
}
Have tried before document.setPageSize:
log.debug( "Adding 90 to rotate" );
int currRot = pageRot.intValue();
currRot += 90;
currRot %= 360;
com.itextpdf.text.pdf.PdfNumber newRot = new
com.itextpdf.text.pdf.PdfNumber( currRot );
pageDict.put(
com.itextpdf.text.pdf.PdfName.ROTATE, newRot );
Also tried:
java.awt.geom.AffineTransform affineTransform = new
java.awt.geom.AffineTransform();
affineTransform.rotate( java.lang.Math.toRadians( 90 ) );
cb.addTemplate( page, affineTransform );
Also tried:
float rotate = 90;
float x = 0;
float y = 0;
float angle = (float)(-rotate * (Math.PI / 180));
float xScale = (float)(Math.cos(angle));
float yScale = (float)(Math.cos(angle));
float xRote = (float)(-Math.sin(angle));
float yRote = (float)(Math.sin(angle));
cb.addTemplate( page, xScale, xRote, yRote, yScale, x, y );
Can anyone point out what I am doing wrong ?
-Thanks
