----------------------------------
Hi, Tilman
Thank you very much for your help.
Use snapshot 2.0.4-166(pdfbox-app-2.0.4-20161128.173807-166.jar), it doesn't
throw this exception.
But another problem comes.
When I get the color space of file pdfbox-test-data1.pdf, it returns DeviceGray.
While I opened it with a text editor (notepad++), I can see the color space
value is DeviceRGB.
The code block:
PDGraphicsState state = getGraphicsState();
System.out.println("Stroke Color Space: " +
state.getStrokingColorSpace()); ←DeviceGray
PDColor strokingColor = state.getStrokingColor();
PDColor nonStrokingColor = state.getNonStrokingColor();
RenderingMode renderingMode = state.getTextState().getRenderingMode();
PDColorSpace colorSpace = strokingColor.getColorSpace();
PDColorSpace ncolorSpace = nonStrokingColor.getColorSpace();
System.out.println(colorSpace.getName()); ←DeviceGray
System.out.println(ncolorSpace.getName()); ←DeviceGray
