Thanks for your great input Konstantin, sorry if I touched your feelings but Qt Webkit is no longer officially maintained by Qt and as far I know - from your own release notes - you ship with known unpatched vulnerabilities
I highly respect your efforts but being able to generate vector SVGs of webpages using webkit-GTK would be clearly a more future-proof approach Thank you Ivan On Fri, Aug 21, 2020 at 11:56 AM Konstantin Tokarev <annu...@yandex.ru> wrote: > > > 21.08.2020, 11:49, "Ivan Klimek" <i...@xclbr.com>: > > Hi Carlos, > > > > thanks for your fast reply > > > > not sure if this helps or if your question was addressed to me - from my > *very* limited understanding - how its done its done in Qt - they have the > qt_svg module that implements methods that directly write vectorized SVG > elements: > > > > void drawEllipse(const QRectF &r) override; > > > > void drawPath(const QPainterPath &path) override; > > > > void drawPixmap(const QRectF &r, const QPixmap &pm, const QRectF &sr) > override; > > > > void drawPolygon(const QPointF *points, int pointCount, PolygonDrawMode > mode) override; > > > > void drawRects(const QRectF *rects, int rectCount) override; > > > > void drawTextItem(const QPointF &pt, const QTextItem &item) override; > > > > void drawImage(const QRectF &r, const QImage &pm, const QRectF &sr, > > > > Qt::ImageConversionFlags flags = Qt::AutoColor) override; > > > > see here: https://github.com/qt/qtsvg/blob/dev/src/svg/qsvggenerator.cpp > > > > from code its used like this: > > > > QWebFrame *frame = m_page.mainFrame(); > > QPainter painter; > > QSvgGenerator svg; > > > > svg.setFileName(fileName); > > svg.setSize(resolution); > > > > painter.begin(&svg); > > > > frame->render(&painter); > > > > and that's all - output is vector SVG - every text / formatting etc all > vector > > > > cairo is able to draw to SVG vectorized too, but the surface types need > to be set correctly when drawing, I took a very light look at webkit-gtk > cairo usage and cairo surface types are image types / aka bitmap so it > draws stuff already to bitmap, and once in bitmap there is no way back :( > but maybe I am reading this wrong, not sure > > > > *I do not know why this is done the way it is done in webkit-gtk, maybe > it would be possible to just internally use svg surfaces?* > > > > would be epic if webkit-gtk could do something like that as Qt Webkit is > dead and there are so many projects using this ... > > QtWebKit is not dead, I'm working on it. > -- > Regards, > Konstantin >
