I get this exception with the attached PDF, and the upper arc of the image is
not rendered:
{code}
java.io.IOException: Unknown colorspace
type:COSDictionary{(COSName{BlackPoint}:COSArray{[COSFloat{0.0}, COSFloat{0.0},
COSFloat{0.0}]}) (COSName{Range}:COSArray{[COSFloat{-128.0}, COSFloat{127.0},
COSFloat{-128.0}, COSFloat{127.0}]})

{code}
There are several causes: (1) in PDICCBased.createColorSpace() the variable
numberOfComponents is -1; (2) the exception is not caught correctly. Both are
fixed in the 2.0 version but not in the 1.8 version. Because the exception
isn't caught correctly, the alternate color space is to be used. (3) The
implementation of getAlternateColorSpaces() (that part existed before it became
an apache project) thinks that this is an array of colorspaces.This
{code}
[/Lab<</BlackPoint[0.0 0.0 0.0]/Range[-128.0 127.0 -128.0
127.0]/WhitePoint[0.964203 1.0 0.824905]>>]
{code}
is considered an array of two colorspaces. This is contrary to the spec, which
mentions "An alternate colour space". I will fix the bug without changing the
API in 1.8, but will change the API in 2.0, which will be
{code}
public PDColorSpace getAlternateColorSpace() throws IOException
{code}
instead of
{code}
public List<PDColorSpace> getAlternateColorSpaces() throws IOException
{code}
