Method Detail

getBitsPerCoordinate

public int getBitsPerCoordinate()

Gets the number of bits used to represent each vertex coordinate.

Returns:

the number of bits. Can be 1, 2, 4, 8, 12, 16, 24, or 32

setBitsPerCoordinate

public final void setBitsPerCoordinate(int bitsPerCoordinate)

Sets the number of bits used to represent each vertex coordinate.

Parameters:

bitsPerCoordinate - the number of bits to be set. Shall be 1, 2, 4, 8, 12, 16, 24, or 32

getBitsPerComponent

public int getBitsPerComponent()

Gets the number of bits used to represent each colour component.

Returns:

the number of bits. Can be 1, 2, 4, 8, 12, or 16

setBitsPerComponent

public final void setBitsPerComponent(int bitsPerComponent)

Sets the number of bits used to represent each colour component.

Parameters:

bitsPerComponent - the number of bits to be set. Shall be 1, 2, 4, 8, 12, or 16

The ranges shall be specified as follows: [x_min x_max y_min y_max c1_min c1_max … cn_min cn_max]. Only one pair of color values shall be specified if a Function entry is present.

Parameters:

decode - the float[] of Decode object to set

setDecode

public final void setDecode(PdfArray decode)

Sets the PdfArray of numbers specifying how to map vertex coordinates and colour components into the appropriate ranges of values.
