why does text change color when using saveas() or print()?

Hi,

I'm having trouble saving a picture with added text in white. Eventhoug the text is shown as white (or red or which ever other color) in the matlab figure, it becomes black when i save it as a pdf using saveas() or print(). Saving in a different file format does not work either.

 Img = imread('Img.tif');
 h = figure;
   imshow(Img); 
   hold on;
      for j = 1:size(TextPosition,2)
          text(TextPosition(j,1),TextPosition(j,2),num2str(j),'Color','w','FontWeight', 'bold');
      end
      saveas(gcf,'ImgWithText.pdf');
      close;

TextPosition is just a list of positions where text should be added.

Does anyone know whats going on?

Best /Anne
