Detailed Description

colors in QPixmap

Starting from a base pixmap, this class generates new pixmaps with one color replaced (for instance, all pink pixels changed to green).

Creates a colorizer that will replace every pixel of the given hue.

Passing a negative hue disables colorization.

base()

QPixmap freeciv::colorizer::base ( ) const

inline

Returns the base pixmap used by this colorizer.

pixmap()

const QPixmap * freeciv::colorizer::pixmap

(

const QColor &

color

)

const

Returns a pixmap with some pixels changed to the target color.

The pixmap is cached for later use.
