Constructor Details

PDShadingType5

public PDShadingType5(COSDictionary shadingDictionary)

Constructor using the given shading dictionary.

Parameters:

shadingDictionary - the dictionary for this shading

Method Details

getShadingType

public int getShadingType()

Description copied from class: PDShading

This will return the shading type.

Specified by:

getShadingType in class PDShading

Returns:

the shading typ

getVerticesPerRow

public int getVerticesPerRow()

The vertices per row of this shading. This will return -1 if one has not been set.

Returns:

the number of vertices per row

setVerticesPerRow

public void setVerticesPerRow(int verticesPerRow)

Set the number of vertices per row.

Parameters:

verticesPerRow - the number of vertices per row

toPaint

public Paint toPaint(Matrix matrix)

Description copied from class: PDShading

Returns an AWT paint which corresponds to this shading

Specified by:

toPaint in class PDShading

Parameters:

matrix - the pattern matrix concatenated with that of the parent content stream, this matrix which maps the pattern's internal coordinate system to user space

Returns:

an AWT Paint instance
