Need advise about my project target using Spire.PDF

[hachi1030]

Hello guys,

I am now writing a project for my work. Here are the details:

I will have a template pdf file such as a contract. In the contract I will leave some blanks for filling, such as contractor: _______.

Now I am writing a project based on .Net C# winform to automatically fulfill the blanks in the pdf file. I need to find the key word such as contractor and then fulfill the blank using the string that I have input in the winform input box.

I would like to use spire.PDF. Is there any one who can advise what function I can use to archive this target?

Thanks very much!

Hello,

Thanks for your inquiry.
You can use the FormField to archive this target.
There is the tutorial in our website about how to create FormField in your template pdf file.

Great, thanks. I have read these 2 articles before. I would like to ask can I separate the form elements into the contract to make it like a contract not a form? Also, can I modify the css of the form to make it as a blank not a input box?

Hello,

Thanks for your reply.
Suppose you already have the template pdf file. I recommend you to find the key word first, then find the position. Finally, you can draw the text directly in the position.
Here is the code for your reference.

Code: Select all

 PdfDocument pdf = new PdfDocument();
            PdfUnitConvertor unitCvtr = new PdfUnitConvertor();
            PdfMargins margin = new PdfMargins();
            margin.Top = unitCvtr.ConvertUnits(2.54f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
            margin.Bottom = margin.Top;
            margin.Left = unitCvtr.ConvertUnits(3.17f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
            margin.Right = margin.Left;
            PdfPageBase page = pdf.Pages.Add();
            PdfFont font = new PdfFont(PdfFontFamily.Helvetica, 12f);
            PdfSolidBrush brush = new PdfSolidBrush(Color.Black);
            PdfPen pen = PdfPens.Black;
            string label = "contractor:";
            float x = 0;
            float y = 10;
            page.Canvas.DrawString(label, font, brush, x, y);
            float width = font.MeasureString(label).Width;
            float height = font.MeasureString(label).Height;
            x = x + width + 3;
            y = y + height;
            float lineEndx = 130;
            page.Canvas.DrawLine(pen, x, y, lineEndx, y);
            pdf.SaveToFile("5635.pdf");
            PdfDocument pdf1 = new PdfDocument("5635.pdf");
            PdfTextFind[] result1 = null;
            result1 = pdf1.Pages[0].FindText("contractor").Finds;
            foreach (PdfTextFind find in result1)
            {
                float Textx = find.Position.X + width+3;
                float texty = find.Position.Y-2;
                pdf1.Pages[0].Canvas.DrawString("your input", font, brush, Textx, texty);
                break;
            }
            pdf1.SaveToFile("5635-1.pdf");

Great, this code will help a lot! I am trying to draw the string. Also, I assume that I can put a form input field appending to a text and operate that too right?

Another question, whenever I create a new pdf file, there will be red string in the top which is "Evaluation Warning : The document was created with Spire.PDF for .NET.". Can I do some settings to make sure that this string will not be added into my pdf whenever I create a new pdf?

Hello,

Thanks for your reply.
1. Yes.
2. You could contact our sales team(sales@e-iceblue.com) to get a temporary license file to remove the warning message and have a better evalution on our products.
