Creates a new instance of PatternType1

Method Details

parse

protected void parse(PDFObject patternObj,
 Map rsrc)
              throws IOException

Parse the pattern from the PDFObject Note the resources passed in are ignored...

Specified by:

parse in class PDFPattern

Parameters:

patternObj - the pdfobject with data for this pattern

Throws:

IOException

getPaint

public PDFPaint getPaint(PDFPaint basePaint)

Create a PDFPaint from this pattern and set of components. This creates a buffered image of this pattern using the given paint, then uses that image to create the correct TexturePaint to use in the PDFPaint.

Specified by:

getPaint in class PDFPattern

Parameters:

basePaint - the base paint to use, or null if not needed

getResources

public HashMap<String,PDFObject> getResources()

get the associated resources

getPaintType

public int getPaintType()

get the paint type

getTilingType

public int getTilingType()

get the tiling type

getBBox

public Rectangle2D getBBox()

get the bounding box

getXStep

public int getXStep()

get the x step

getYStep

public int getYStep()

get the y step
