A little bug in color of annotations?

Hi,
I have a little issue with colors of annotations. Suppose these steps:

1) Add some annotation to document
2) Set fill color for this annotation to 0xFFFFFF01.
3) Call GetFillColor on this annotation. The returned value is 0xFFFFFF00.

The color values are different. For other colors (e.g. 0xFFFF0000) is works fine), but exactly for color 0xFFFFFF01 it does not work fine.
Is this some bug in your library?

Thanks in advance.

in PDF file, color value saved as float values.
and SDK using int values, convert to float is (1.0/255)
and get color may loss small float point value by int type convertion.
