private void ensureExtendedState()

setupLuminosityMasking

public void setupLuminosityMasking(java.awt.image.BufferedImage image,
                                   org.apache.pdfbox.pdmodel.common.PDRectangle boundingBox)
                            throws java.io.IOException

Setup a mask for the next fill/stroke operation

Parameters:

image - the mask image. It will be used to generate a grayscale image, that will directly map to the alpha channel.

boundingBox - The bounding box of the masking. I.e. where to apply the mask

Throws:

java.io.IOException

setupLuminosityMasking

public void setupLuminosityMasking(org.apache.pdfbox.pdmodel.graphics.form.PDFormXObject formXObject)
                            throws java.io.IOException

Setup a mask for the next fill/stroke operation. It will use the BBox of the formXObject.

Parameters:

formXObject - the mask form. It will be used to generate a grayscale image, that will directly map to the alpha channel.

Throws:

java.io.IOException

setupLuminosityMasking

public void setupLuminosityMasking(org.apache.pdfbox.pdmodel.graphics.PDXObject maskXObject,
                                   org.apache.pdfbox.pdmodel.common.PDRectangle boundingBox)
                            throws java.io.IOException

Setup a mask for the next fill/stroke operation.

Parameters:

maskXObject - a PDXObject (form or image) which generates a grayscale image for the masking. This image will directly map to the alpha channel.

boundingBox - The bounding box of the masking. I.e. where to apply the mask

Throws:

java.io.IOException
