Print RichText and a scaled Picture

[tpf80]

Here is how I worked out a similar issue for rich text PDF based off of Qwt example:

void PdfGenerate::generatePdf() {
 
 
	QPrinter printer; //create a printer
	printer.setOrientation(QPrinter::Portrait); //set theorientation of the paper
	printer.setOutputFormat(QPrinter::PdfFormat); //make that printer as a PDF
	printer.setOutputFileName("test.pdf"); //set the PDF file name
	printer.setPaperSize(QPrinter::Letter); //set paper size
	printer.setFullPage(true); //let our app use the full page (we handle margins ourself)
 
	setupLetterPoints(); //set up reference points for our coordinate system
 
	QPainter painter(&printer); //make a painter, which uses this printer,
 
 
 
	QTextDocument clause;
	QPixmap logo("logo.jpg", "JPG");
	clause.addResource(QTextDocument::ImageResource, QUrl("logo.jpg"), logo);
	clause.setHtml("<img src=\"logo.jpg\"><br><b>clause:</b> Here is some text<br>Here is another line of text");
	clause.setDefaultFont(QFont(fontFamily, fontsize));
	QRectF r5(leftmargin, topmargin, 500, 500); //space our textdocument is allowed to take up and where it should be located
	drawrichtext(&painter, r5, 0, clause);
 
	painter.end(); //done drawing, so save the PDF 
	//open the PDF for viewing:
	QString sOldPath = QCoreApplication::applicationDirPath();
	QDesktopServices::openUrl(QUrl::fromLocalFile(sOldPath + "/test.pdf"));
 
 
 
}
 
//set up the point coordinates for a letter sheet of paper:
void PdfGenerate::setupLetterPoints() {
	//(86 / inch) so it seems..
	pagewidth = 731; //8.5 inch
	pageheight = 946; //11 inch
 
	margin = 43; // 0.5 inch margin
 
	topmargin = margin;
	bottommargin = pageheight - margin;
	leftmargin = margin;
	rightmargin = pagewidth - margin;
 
	vertmarginwidth = pageheight - (margin * 2);
	horizmarginwidth = pagewidth - (margin * 2);
 
	//font sizes:
	fontFamily = "Times New Roman";
	fontsize = 15;
 
 
}
 
void PdfGenerate::drawrichtext(QPainter *painter, QRectF &rect, int flags, QTextDocument &text) {
 
    text.setPageSize(QSize(rect.width(), QWIDGETSIZE_MAX));
 
    QAbstractTextDocumentLayout* layout = text.documentLayout();
 
    const int height = qRound(layout->documentSize().height());
    int y = rect.y();
    if (flags & Qt::AlignBottom)
        y += (rect.height() - height);
    else if (flags & Qt::AlignVCenter)
        y += (rect.height() - height)/2;
 
    QAbstractTextDocumentLayout::PaintContext context;
    context.palette.setColor(QPalette::Text, painter->pen().color());
 
    painter->save();
 
    painter->translate(rect.x(), rect.y());
    layout->draw(painter, context);
 
    painter->restore();
}

void PdfGenerate::generatePdf() {


	QPrinter printer; //create a printer
	printer.setOrientation(QPrinter::Portrait); //set theorientation of the paper
	printer.setOutputFormat(QPrinter::PdfFormat); //make that printer as a PDF
	printer.setOutputFileName("test.pdf"); //set the PDF file name
	printer.setPaperSize(QPrinter::Letter); //set paper size
	printer.setFullPage(true); //let our app use the full page (we handle margins ourself)
	
	setupLetterPoints(); //set up reference points for our coordinate system

	QTextDocument clause;
	QPixmap logo("logo.jpg", "JPG");
	clause.addResource(QTextDocument::ImageResource, QUrl("logo.jpg"), logo);
	clause.setHtml("<img src=\"logo.jpg\"><br><b>clause:</b> Here is some text<br>Here is another line of text");
	clause.setDefaultFont(QFont(fontFamily, fontsize));
	QRectF r5(leftmargin, topmargin, 500, 500); //space our textdocument is allowed to take up and where it should be located
	drawrichtext(&painter, r5, 0, clause);

	painter.end(); //done drawing, so save the PDF 
	//open the PDF for viewing:
	QString sOldPath = QCoreApplication::applicationDirPath();
	QDesktopServices::openUrl(QUrl::fromLocalFile(sOldPath + "/test.pdf"));

   

}

//set up the point coordinates for a letter sheet of paper:
void PdfGenerate::setupLetterPoints() {
	//(86 / inch) so it seems..
	pagewidth = 731; //8.5 inch

	bottommargin = pageheight - margin;

	vertmarginwidth = pageheight - (margin * 2);
	horizmarginwidth = pagewidth - (margin * 2);
	
	//font sizes:

	fontsize = 15;
	

}

void PdfGenerate::drawrichtext(QPainter *painter, QRectF &rect, int flags, QTextDocument &text) {

    text.setPageSize(QSize(rect.width(), QWIDGETSIZE_MAX));

    QAbstractTextDocumentLayout* layout = text.documentLayout();

    const int height = qRound(layout->documentSize().height());
    int y = rect.y();
    if (flags & Qt::AlignBottom)
        y += (rect.height() - height);
    else if (flags & Qt::AlignVCenter)
        y += (rect.height() - height)/2;

    QAbstractTextDocumentLayout::PaintContext context;
    context.palette.setColor(QPalette::Text, painter->pen().color());

    painter->save();

    painter->translate(rect.x(), rect.y());
    layout->draw(painter, context);

    painter->restore();
}
