Function Documentation

KLF_EXPORT void klfDrawGlowedImage	(	QPainter *	painter,
		const QImage &	foreground,
		const QColor &	glow_color = QColor(128, 255, 128, 8),
		int	radius = 4,
		bool	also_draw_image = true
	)

Draws the given image with a glow effect.

Draws a glow effect for image foreground by extracting the alpha channel, and creating fills an image of color glow_color with the same alpha channel. The image is then drawn at all points (x,y) around (0,0) such that |(x,y)-(0,0)| < r, effectively overlapping the glow image with itself creating a blur effect.

The resulting graphics are painted using the painter painter, at the reference position (0,0). If you want your image drawn at another position, use QPainter::translate().

If also_draw_image is TRUE, then the image itself is also drawn on top of the glow effect.
