Field Image

[Martin Sato]

Good day,

  How can assign value to my Image/Button field created from Adobe Acrobat DC Pro, I don't see corresponding field in Syncfusion.

Thank you.

Hi Martin Sato, 

Greetings from Syncfusion. 

As per the PDF specification, there is no separate form field for adding images. As a workaround we can achieve your requirement by creating new button field and replacing it to the existing one, please refer the below code for further details: 

PdfLoadedDocument loadedDocument = new PdfLoadedDocument( pdfStream, true); 

PdfLoadedForm loadedForm = loadedDocument.Form; 

for (int i = 0; i < loadedForm.Fields.Count; i++) 

{ 

Console.WriteLine(loadedForm.Fields[i].Name + " "+i); 

if (loadedForm.Fields[i] is PdfLoadedButtonField) 

{ 

PdfLoadedButtonField loadedField = loadedForm.Fields[i] as PdfLoadedButtonField; 

//Create new field and clone its parameters 

PdfButtonField field = new PdfButtonField(loadedField.Page, loadedField.Name); 

field.Bounds = loadedField.Bounds; 

field.BorderColor = loadedField.BorderColor; 

field.BorderStyle = loadedField.BorderStyle; 

field.BorderWidth = loadedField.BorderWidth; 

PdfImage image = new PdfBitmap(imageStream); 

//Add image to the appearance stream of the created field 

field.Appearance.Normal.Graphics.DrawImage(image, new RectangleF(0,0, field.Appearance.Normal.Width, field.Appearance.Normal.Height) ); 

// remove the existing field 

loadedForm.Fields.Remove(loadedField); 

//Add the new field 

loadedForm.Fields.Add(field); 

 

} 

} 

 

MemoryStream ms = new MemoryStream(); 

 

loadedDocument.Save(ms); 

loadedDocument.Close(true); 

Let us know if you need any further information.
