Constructor Detail

QColormap

public QColormap(QColormap colormap)

Constructs a copy of another colormap.

Method Detail

colorAt

public final QColor colorAt(int pixel)

Returns a QColor for the pixel.

pixel().

colormap

public final java.util.List colormap()

Returns a vector of colors which represents the devices colormap for Indexed and Gray modes. This function returns an empty vector for Direct mode.

See also:

size().

depth

public final int depth()

Returns the depth of the device.

See also:

size().

mode

public final QColormap.Mode mode()

Returns the mode of this colormap.

QColormap::Mode .

pixel

public final int pixel(QColor color)

Returns a device dependent pixel value for the color.

See also:

colorAt().

size

public final int size()

Returns the size of the colormap for Indexed and Gray modes; Returns -1 for Direct mode.

See also:

colormap().

instance

public static QColormap instance()

Returns the colormap for the specified screen. If screen is -1, this function returns the colormap for the default screen.

instance

public static QColormap instance(int screen)

Returns the colormap for the specified screen. If screen is -1, this function returns the colormap for the default screen.
