Description copied from interface: DrawCmd

Called by the Shapes class to paint all DrawCmd implementations.

Specified by:

paintOperand in interface DrawCmd

Specified by:

paintOperand in class AbstractDrawCmd

Parameters:

g - graphics context to paint this paint command to.

parentPage - parentPage reference used to notify page painters.

currentShape - current shape to draw.

clip - clip of parent which is the generally the page size.

base - base transform of the page.

optionalContentState - state of optional content visibility.

paintAlpha - enable/disable the alpha painting.

paintTimer - painTimer keeps track when a repaint should occur.

Returns:

resulting shape if currentShape has been altered, otherwise returns the currentShape. Current Shape is generally altered clip shape.

getAlphaComposite

public java.awt.AlphaComposite getAlphaComposite()

Gets the alpha value that is applied to the graphics context.

Returns:

alpha context which will be applied by this command.

setAlphaComposite

public void setAlphaComposite(java.awt.AlphaComposite alphaComposite)

Sets the alpha composite to be executed by this command. Care should be taken as this will have direct impact on the PDF shapes stack on the next paint call.

Parameters:

alphaComposite - alphaComposite object to be executed by this command.
