          Description

          There are two bugs in PDFGraphics2D.applyColor.

          Firstly, when applying a color with CMYK colorspace the number of components is 4, not 3.
          See line 744:
          float[] cComps = c.getColorComponents(new float[3]); //results in ArrayIndexOutOfBoundsException

          Secondly, Color.getColorComponents returns values in the range [0, 1] while PDFColor expects them in the [0, 255] range.

          I attached the patch and a sample program to reproduce the trouble.

          Regards,
          Yegor kozlov

            Thanks for noticing that bug. I've just fixed it but not using your patch as it contained a bug (*256 is not correct) and it was possible to this in a much simpler way.
