TransparencyGroup

private TransparencyGroup(PDTransparencyGroup form,
 boolean isSoftMask,
 Matrix ctm,
 PDColor backdropColor)
                   throws IOException

Creates a buffered image for a transparency group result.

Parameters:

form - the transparency group of the form or soft mask.

isSoftMask - true if this is a soft mask.

ctm - the relevant current transformation matrix. For soft masks, this is the CTM at the time the soft mask is set (not at the time the soft mask is used for fill/stroke!), for forms, this is the CTM at the time the form is invoked.

backdropColor - the color according to the /bc entry to be used for luminosity soft masks.

Throws:

IOException
