virtual void DtQtDrawer::drawImage	(	const DtDisplayPoint &	pt,
		const QImage &	p,
		bool	blend = true,
		int	transparencyLevel = 0
	)		[virtual]

This call differs from drawPixmap in that if the supplied image contains an alpha mask, it will blend the image with the current background image using that mask.

If you do not need this type of blending, use the drawPixmap call to simply use the monochrome bitmap (if it exists).

Transparency level is set from 0 to 100. This will override any alpha channel or blend flag, as, if non-zero, will pick that as the percent of pixel to display (0 being opaque, 1 being completely transparent)

Implements DtPrimitiveDrawer.

erase with fillcolor

Implements DtPrimitiveDrawer.

virtual void DtQtDrawer::labelForHorizLine	(	const DtDisplayPoint &	pt,
		const char *	pString
	)		[virtual]

clientWnd() and setClientWnd() used to get/set the window which will be drawn upon call this before calling

Grid line stuff.

Implements DtPrimitiveDrawer.

virtual void DtQtDrawer::labelForVertiLine	(	const DtDisplayPoint &	pt,
		const char *	pString
	)		[virtual]

Implements DtPrimitiveDrawer.

virtual void DtQtDrawer::internalDrawImage	(	int	x,
		int	y,
		const QImage &	image
	)		[virtual]

Because all Qt does internally is convert images to pixmaps before drawing, for very large images, this does not work.

Here will will pick and image size and draw "slices" of the image if the image is too large to draw
