Find text and change fore color

[AmisHealth]

I want to find a text and change the fore color of that text.

I have been trying the below code but it doesnot change.


Spire.Pdf.General.Find.PdfTextFind[] text2 = page2.FindText("<PLACE1>", TextFindParameter.WholeWord).Finds;

PdfBrush brush = new PdfSolidBrush(Color.DarkBlue);

RectangleF rec;

PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", 12f, FontStyle.Regular));

foreach (Spire.Pdf.General.Find.PdfTextFind seletion in text2)
{

rec = seletion.Bounds;

page2.Canvas.DrawRectangle(PdfBrushes.White, rec);

page2.Canvas.DrawString("<PLACE1>", font, brush, rec);
}

I have tried to apply highlight and that also doesnot work.
Please help.

Thank you

Hello,

Thanks for your inquiry.
I simulated a pdf file and tested your code with the latest Spire.PDF Pack(Hot Fix) Version:7.8.8, but I did not reproduce your issue. If you are using an older version, we recommend you upgrade to the latest version and try again.
If the issue persists, please provide your input file for further investigation. Thanks in advance for your assistance.

Hi,

What I am trying to achieve is I have a pdf file with <TEST> which is set to fore color white.

I want to set <TEST> to fore color black and replace the text to todays date. But it always returns a empty pdf.

The test pdf file attached.

Code below and file attached.

Spire.Pdf.General.Find.PdfTextFind[] text2 = page1.FindText("<TEST>", TextFindParameter.WholeWord).Finds;

PdfBrush brush = new PdfSolidBrush(Color.Black);

RectangleF rec;

PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", 9f, FontStyle.Regular));
foreach (Spire.Pdf.General.Find.PdfTextFind seletion in text2)
{

rec = seletion.TextBounds[0];

page1.Canvas.DrawRectangle(PdfBrushes.Black, rec);

page1.Canvas.DrawString("<TEST>", font, brush, rec);
}

ptr1.ReplaceText("<TEST>", "08/24/2021");

doc.SaveToFile(@"C:\Test1.pdf");

Hello,

Thanks for your response.
Please refer to the following modified code.

Code: Select all

            PdfDocument doc = new PdfDocument("test.pdf");
            PdfPageBase page1 = doc.Pages[0];

            Spire.Pdf.General.Find.PdfTextFind[] text2 = page1.FindText("<TEST>", TextFindParameter.WholeWord).Finds;

            PdfBrush brush = new PdfSolidBrush(Color.Black);

            RectangleF rec;

            PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", 9f, FontStyle.Regular));
            foreach (Spire.Pdf.General.Find.PdfTextFind seletion in text2)
            {
                List<RectangleF> textBounds = seletion.TextBounds;

                rec = seletion.TextBounds[0];
                page1.Canvas.DrawRectangle(PdfBrushes.White, rec);

                page1.Canvas.DrawString("08/24/2021", font, brush, rec.X, rec.Y);
            }

            doc.SaveToFile(@"Test1.pdf");
