Just because colour is passed to your Enum proc, does not mean that changing your parameters changes the colour. This is a read only method. To edit page contents use PDFEdit methods. Tip 1: PDFEdit use needs a detailed understanding of the PDF graphics and text model. Tip 2: there is no mapping from text selection to PDFEdit objects, you have to reselect the objects based on their geometry. Tip 3: This is much more work than anyone wants it to be.

    If you want to change the color, or any other content stream parameters, you have to rebuild the content stream.

    I found that the color of the text can be changed in the Callback PDTextSelectEnumTextProc. I have done the following:

    color->space = PDDeviceRGB;
    color->value[0] = 0;
    color->value[1] = 0;
    color->value[2] = 255;

    However, the color of the characters does not change. Where am I wrong?

    I want to change the color of the text in the selected fragment of the PDF document. For this fragment
      AVDocGetSelectionType (avDoc) == ASAtomFromString ("Text"))
