Tilman Hausherr commented on PDFBOX-3063:
-----------------------------------------
Please try this - in your derived class, put this in your constructor:
{code}
addOperator(new SetStrokingColorSpace());
addOperator(new SetNonStrokingColorSpace());
addOperator(new SetStrokingDeviceCMYKColor());
addOperator(new SetNonStrokingDeviceCMYKColor());
addOperator(new SetNonStrokingDeviceRGBColor());
addOperator(new SetStrokingDeviceRGBColor());
addOperator(new SetStrokingColor());
addOperator(new SetStrokingColorN());
addOperator(new SetNonStrokingColor());
addOperator(new SetNonStrokingColorN());
{code}
this is from the preflight code... I see two are missing, so add these too:
SetNonStrokingDeviceGrayColor and SetStrokingDeviceGrayColor.
> Appears that getStrokingColor/getNonStrokingColor are broken

> Project: PDFBox
> Issue Type: Bug
> Components: Text extraction
> Reporter: Joel Hirsh
> Attachments: whitetext.pdf
>
>
> I am using PDFTextStripper and overriding processTextPosition so that I can
> test for white on white text.
> In version 1.8 I called getGraphicsState().getStrokingColor() and
> getGraphicsState().getNonStrokingColor() to get the colors and then could
> test for white on white text.
> In version 2.0 I am making the same calls on the same file, but the PDColor
> returned for both methods never changes from PDColor{components=[0.0],
> patternName=null}
> In the attached file, there is some white text '661.37' just above and to the
> left of the 2.00. Can find it in Acrobat by searching or careful selecting
