Method Detail

getDictionary

public COSDictionary getDictionary()

This will get the dictionary that stores the image parameters.

Returns:

The COS dictionary that stores the image parameters.

getBitsPerComponent

public int getBitsPerComponent()

The bits per component of this image. This will return -1 if one has not been set.

Returns:

The number of bits per component.

setBitsPerComponent

public void setBitsPerComponent(int bpc)

Set the number of bits per component.

Parameters:

bpc - The number of bits per component.

getColorSpace

public PDColorSpace getColorSpace()
                           throws IOException

This will get the color space or null if none exists.

Returns:

The color space for this image.

Throws:

IOException - If there is an error getting the colorspace.

getColorSpace

public PDColorSpace getColorSpace(Map colorSpaces)
                           throws IOException

This will get the color space or null if none exists.

Parameters:

public void setFilters(List filters)

This will set the filters that are part of this stream.

Parameters:

filters - The filters that are part of this stream.

isStencil

public boolean isStencil()

Returns true if the image is a stencil mask.

Returns:

true if the image is a stencil mask.

setStencil
