Find and replace text,replacing text with white space

[jenishItact]

Hi

I am using freespire.pdf(8.6.0) Version in .Net Core Project (.Net - 6 )

As I am try to replacing texts in pdf with new words but it replace with only white space,no new word is replaced there

I also tried with different way and example provied on e-iceblue official site but not works

Please see below my code

var templatePath = Path.Combine(GoatSignConsts.TemplatePath, template.TenantId.ToString(), template.FileName);

PdfDocument doc = new PdfDocument();
doc.LoadFromFile(templatePath);
PdfUsedFont pdfFont = doc.UsedFonts[0];

PdfTextFindCollection collection = page.FindText("{{Name}}", TextFindParameter.WholeWord);

RectangleF rec;

//Creates a brush
PdfBrush brush = new PdfSolidBrush(Color.DarkBlue);

foreach (PdfTextFind find in collection.Finds)
{
float.TryParse((pdfFont.Size + 2).ToString(), out float fontSize);
PdfTrueTypeFont font;

try
{
font = new PdfTrueTypeFont(new Font(new FontFamily(pdfFont.Name), 12, FontStyle.Regular), fontSize, true);
}
catch (Exception)
{
font = new PdfTrueTypeFont(new Font(new FontFamily("Arial"), 12, FontStyle.Regular), fontSize, true);
}

// Gets the bound of the found text in page
rec = find.TextBounds.FirstOrDefault();
//rec.Y = rec.Y + 1;
page.Canvas.DrawRectangle(PdfBrushes.White, rec);
page.Canvas.DrawString("Replaced One", font, brush, rec);
}


We have also applied other methods but we are facing lots of issue with layout and words position

Also Tried this

foreach (PdfTextFind find in collection.Finds)
{
//replace word in pdf
find.ApplyRecoverString(dVariable.Value, Color.White, true);
}

Please take a look and because we tried with different applications

Hi,

Thanks for your inquiry.
I did a test with the document you provided, using the free Spire.PDF_8.6.0, but I did not reproduce your issue, the newly added words are displayed in the result document, I have attached it for your reference. Partial text display is incomplete due to insufficient rectangular width.

If you have any further questions or concerns, just feel free to contact us.

Hi Thanks For your reply

Please try with document file i have attached names Template2.pdf

Here i am replacing {{Name}} {{Profession}} {{template}} {{Answer}} with new words

Also i have attached result of above sample 638215628561506445_Template2.pdf but result show white space replaced not text replaced
Note : its with trial licence version but you can see result is same for licence and free version

In ImportantWplaceholders.zip you can try to replace {{goal}} with new word give same result with blank space


here

page.Canvas.DrawRectangle(PdfBrushes.White, rec); //This line is replacing white object
page.Canvas.DrawString(newText, font, brush, rec); // but this line is not working

Hi,

Thanks for your feedback.
After debugging the issue, I found that the font size you used to draw the new text was larger than the original font size (11.04), the height of the newly added text box is lower than the height of the newly added text, which caused the new text not to be displayed. To resolve this issue, you can set the font size to be smaller than or equal to the font size of the text being replaced, or use the following code to force the text to be displayed.

Code: Select all

PdfStringFormat format = new PdfStringFormat();
format.LineLimit = true;
page.Canvas.DrawRectangle(PdfBrushes.White, rec);
page.Canvas.DrawString("hello", font, brush, rec,format);


Regarding your another question, our latest version of the PDF product has changed its licensing method. Please refer to the following code:

Code: Select all

Spire.Pdf.License.LicenseProvider.SetLicenseKey("");


If you have any further questions or concerns, please don't hesitate to contact us.
