void setPixmap(bool isGnuplot, const Transformation &transformation, const DocumentModelGridRemoval &modelGridRemoval, const DocumentModelColorFilter &modelColorFilter, const QPixmap &pixmapOriginal, const QString &curveSelected)
Update the images of all states, rather than just the current state.
Background image state for showing filter image from current curve.
void requestStateTransition(BackgroundState backgroundState)
Initiate state transition to be performed later, when BackgroundState is off the stack.
Background image state for showing no image.
