Description

I have PDF document where I am modifying PDPage content stream.
Saved document is invalid (Adobe reader complains about it).

I have narrowed it down to ColorSpace.

Original document has colorspace:
/ColorSpace <<
/Cs6 [/ICCBased <<
/Alternate /DeviceRGB
/Filter /FlateDecode
/Length 2597
/N 3
>>]>>

Modified document has colorspace:
/ColorSpace <<
/Cs6 [/ICCBased <<
/Alternate /DeviceRGB
/Filter /FlateDecode
/Length 2597
/N 3
/Range []
>>]>>

When I manually remove "/Range []" from PDF then Adobe reader opens it without an error.

Obviously that range is added by calling PDICCBased.getRangeArray(0) somewhere.
