Edit PDF Text

Hi,

I want to be able to find and edit text on a page...

I understand I can use the GetPageText to find the text I'm after, Now that I have the location etc... i need to edit the text.

What is the best way...

Can the text be edited directly?

Can I recreate a new PDF with all the existing content except the "text" and then draw my new text? If so how?

Thanks,

Hi,

I have noticed that the GetPageText function returns the color in RGB even though my text in the PDF is saved as CMYK

What is the best way to convert the RGB to CMYK?

I use the following function below... but what I would like to know is the function used by Quick PDF to convert CMYK to RGB? that way it can be reversed to preserve color

    public class Cmyk
    {
        public double C { get; set; }
        public double M { get; set; }
        public double Y { get; set; }
        public double K { get; set; }

        public Cmyk(double r, double g, double b)
        {
            double R = 1.0 - r;
            double G = 1.0 - g;
            double B = 1.0 - b;

            if (R < G)
            {
                K = R;
            }
            else
            {
                K = G;
            }
            if (B < K)
            {
                K = B;
            }

            C = CalcCmyk(r, K);
            M = CalcCmyk(g, K);
            Y = CalcCmyk(b, K);
        }

        private static double CalcCmyk(double rgb, double k)
        {
            if (((1 - rgb - k) <= 0) || ((1 - k) <= 0))
            {
                return 0;
            }
            return (1 - rgb - k) / (1 - k);
        }
    }

Will this preserve the color 100%

Thanks,
