[iText-questions] problem with rounded corners
Hi, I have problems with rounded corners. If I use the cb directly here and
don't create a Pdftemplate everythings works fine with the rounded corners
but if the background I set every block in my page will get them.
cell.setCellEvent( new PdfPCellEvent(){
public void cellLayout(PdfPCell cell, Rectangle rect,PdfContentByte[]
canvas) {
// Here I have tried to just add it to the PdfContentByte but then every
block
// is the color of the last block. I've tried cb.saveState() and
restoreState() but without luck
PdfContentByte cb = canvas[PdfPTable.LINECANVAS];
PdfTemplate template = cb.createTemplate( rect.getWidth() ,
rect.getHeight());
if( getBorder() != null ){
template.setLineWidth( MeasurementUtil.millimetersToPostscriptPoints(
getBorder().getThickness()) );
template.setColorStroke( getPage().getPdfDocument().getColors().get(
getBorder().getColorReference() ));
}
if( getBackgroundReference() != null ){
template.setColorFill( getPage().getPdfDocument().getColors().get(
getBackgroundReference() ));
}
template.roundRectangle(0 , 0, rect.getWidth() ,rect.getHeight() ,
MeasurementUtil.millimetersToPostscriptPoints( getRadius() ));
if( getBackgroundReference() != null || getBorder() != null ){
if( getBackgroundReference() != null getBorder() != null ){
template.fillStroke();
}else if( getBackgroundReference() != null ){
template.fill();
}else{
template.stroke();
}
}
cb.addTemplate( template, rect.getLeft(), rect.getBottom());
}});

Re: [iText-questions] problem with rounded corners
can anyone give me some pointer on why PdfTemplate.roundRectangle() doesn't make fine edges as PdfContentByte does? -- View this message in context: http://old.nabble.com/problem-with-rounded-corners-tp28328340p28329580.html Sent from the iText - General mailing list archive at Nabble.com. -- ___ iText-questions mailing list iText-questions@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.itextpdf.com/book/ Check the site with examples before you ask questions: http://www.1t3xt.info/examples/ You can also search the keywords list: http://1t3xt.info/tutorials/keywords/
Re: [iText-questions] problem with rounded corners
PdfTemplate extends PdfContentByte, there's no reason why the results shouldn't be the same. It would be helpful to see a pdf with those differences.

Re: [iText-questions] problem with rounded corners
Hi,
Yes I'm sure that there is something in my code making this but I can't find
it. I have now managed to remove the sharp edges to smoth but with very odd
settings. I must create a round rectangle twice to make it work.
@Override
public void onRender( PdfContentByte cb ) throws PdfDocumentException{
float width = MeasurementUtil.millimetersToPostscriptPoints( getWidth());
float height = MeasurementUtil.millimetersToPostscriptPoints( getHeight()
);
float left = getLeft();
float top = getTop();
if( getPage().getPdfDocument().getCutMark() != null ){
left += getPage().getPdfDocument().getCutMark().getWidth();
top -= getPage().getPdfDocument().getCutMark().getHeight();
}
PdfTemplate tp = cb.createTemplate(width, height);
tp.roundRectangle(0, 0, width, height,
MeasurementUtil.millimetersToPostscriptPoints( getRadius() ));
cb.addTemplate(tp, MeasurementUtil.millimetersToPostscriptPoints( left ),
MeasurementUtil.millimetersToPostscriptPoints(
getPage().getPdfDocument().getHeight() - ( top + getHeight(;
