Detailed Description
Apply effects to icons.
enum Effects {NoEffect, ToGray, Colorize, ToGamma, DeSaturate, LastEffect }
|
Reread configuration.
QString fingerprint (int group, int state)
|
Returns a fingerprint for the effect selected by
[group,
state].
This is usefull for caching.
QImage apply (QImage src, int group, int state)
|
Apply an effect to an image. The effect to apply depends on the
group
and state
parameters, and is configured by the user.
Parameters:
src | The image.
|
group | The group for the icon.
|
state | The icon's state.
|
Returns: An image with the effect applied.
QImage apply (QImage src, int effect, float value, const QColor rgb, bool trans)
|
Apply an effect to an image.
Parameters:
src | The image.
|
effect | The effect to apply, one of KIconEffect::Effects.
|
value | Strength of the effect. 0 <= value <= 1.
|
color | Color parameter for effects that need one.
|
trans | Add Transparency if trans = true.
|
Returns: An image with the effect applied.
Apply an effect to a pixmap.
QPixmap apply (QPixmap src, int effect, float value, const QColor rgb, bool trans)
|
Apply an effect to a pixmap.
QImage doublePixels (QImage src)
|
Returns an image twice as large, consisting of 2x2 pixels.
void visualActivate (QWidget *, QRect)

Not strictly an 'icon effect', but in practice that's what it looks
like.
