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.
