Locating signature with stretch mode Leave feedback
GroupDocs.Signature provides ability to stretch signature area along page width or height. Use enumeration StretchMode contains following values
- None - no stretch will be applied
- PageWidth - to stretch signature area along page width
- PageHeight - to stretch signature area along page height
- PageArea - to stretch signature area along page width and height
Here are the steps to use stretch mode with adding text or images signatures into document with GroupDocs.Signature:
- Create new instance of Signature class and pass source document path as a constructor parameter.
- Instantiate the TextSignOptions or ImageSignOptions object with all required additional options and setup Stretch property
- Call Sign method of Signature class instance and the instance of signature options (ImageSignOptions for example) to it.
This example shows how to locate signature with stretch mode.
using (Signature signature = new Signature("sample.pdf"))
{
// define several signature options of different types and settings
TextSignOptions textOptions = new TextSignOptions("This is test message")
{
AllPages = true,
VerticalAlignment = VerticalAlignment.Top,
Margin = new Padding(50),
Stretch = StretchMode.PageWidth
};
BarcodeSignOptions barcodeOptions = new BarcodeSignOptions("123456")
{
AllPages = true,
EncodeType = BarcodeTypes.Code128,
VerticalAlignment = VerticalAlignment.Bottom,
Margin = new Padding(50),
Stretch = StretchMode.PageWidth
};
ImageSignOptions imageOptions = new ImageSignOptions()
{
AllPages = true,
Stretch = StretchMode.PageHeight,
HorizontalAlignment = HorizontalAlignment.Right,
ImageFilePath = Constants.ImageHandwrite
};
// define list of signature options
List<SignOptions> listOptions = new List<SignOptions>();
listOptions.Add(textOptions);
listOptions.Add(barcodeOptions);
listOptions.Add(imageOptions);
// sign document to file
signature.Sign("signed.pdf", listOptions);
}
