Field Detail

shadingType

private final int shadingType

Required: The Type of shading (1,2,3,4,5,6,7)

colorSpace

private final PDFDeviceColorSpace colorSpace

A ColorSpace representing the colorspace. "DeviceRGB" is an example.

coords

private final java.util.List<java.lang.Double> coords

Required for Type 2: An Array of four numbers specifying the starting and ending coordinate pairs Required for Type 3: An Array of six numbers [x0,y0,r0,x1,y1,r1] specifying the centers and radii of the starting and ending circles.

function

private final Function function

Required for Type 1, 2, and 3: The object of the color mapping function (usually type 2 or 3). Optional for Type 4,5,6, and 7: When it's nearly the same thing.

extend

private final java.util.List<java.lang.Boolean> extend

Required for Type 2+3: An Array of two boolean values specifying whether to extend the start and end colors past the start and end points, respectively. Default is false, false.

bitsPerCoordinate

private final int bitsPerCoordinate

Required for Type 4,5,6, and 7: Specifies the number of bits used to represent each vertex coordinate. Allowed to be 1,2,4,8,12,16,24, or 32.

bitsPerFlag

private final int bitsPerFlag

Required for Type 4,5,6, and 7: Specifies the number of bits used to represent the edge flag for each vertex. Allowed to be 2,4,or 8, while the Edge flag itself is allowed to be 0,1 or 2.

antiAlias

private final boolean antiAlias

Optional: A flag whether or not to filter the shading function to prevent aliasing artifacts. Default is false.

bitsPerComponent

private final int bitsPerComponent

Required for Type 4,5,6, and 7: Specifies the number of bits used to represent each color coordinate. Allowed to be 1,2,4,8,12, or 16

verticesPerRow

private final int verticesPerRow

Required for Type 5:The number of vertices in each "row" of the lattice; it must be greater than or equal to 2.
