    Locating signature on page with different measure units

    GroupDocs.Signature supports locating signature on document page with different measure units. Enumeration MeasureType handles following types

    • MeasureType.Pixels allows to locate signature position and size with pixels (default value)

    • MeasureType.Millimeters allows to locate signature on page and setup size by setting millimeters

    • MeasureType.Percents allows to locate signature position, size with percentage of page size
         Here are the steps to locate and size signature area with different measure unit types:

    • Set property LocationMeasureType with of one values above to specify how to implement values in properties Left, Top

    • Set property SizeMeasureType with of one values above to specify how to implement size of signature values in properties Width, Height

    • Set property MarginMeasureType with of one values above to specify how to implement values in property Margin

    Set signature positioning in millimeters

    This example shows how to specify positioning in millimeters.

     using (Signature signature = new Signature("sample.docx"))
 {
     // create barcode option with predefined barcode text
     BarcodeSignOptions options = new BarcodeSignOptions("12345678")
     {
         // setup Barcode encoding type
         EncodeType = BarcodeTypes.Code128,
         // set signature position in absolute position
         LocationMeasureType = MeasureType.Millimeters,
         Left = 40,
         Top = 50,
         // set signature area in millimeters
         SizeMeasureType = MeasureType.Millimeters,
         Width = 20,
         Height = 10,
         // set margin in millimeters
         MarginMeasureType = MeasureType.Millimeters,
         Margin = new Padding() { Left =5, Top = 5, Right = 5 },
     };
     // sign document to file
     signature.Sign("signedSample.docx", options);
 }

    Set signature positioning in percents

    This example shows how to set different positioning properties in percentage.

     using (Signature signature = new Signature("sample.pdf"))
 {
     // create barcode option with predefined barcode text
     BarcodeSignOptions options = new BarcodeSignOptions("12345678")
     {
         // setup Barcode encoding type
         EncodeType = BarcodeTypes.Code128,
         // set signature position in absolute position
         LocationMeasureType = MeasureType.Percents,
         Left = 5,
         Top = 5,
         // set signature area in millimeters
         SizeMeasureType = MeasureType.Percents,
         Width = 10,
         Height = 5,
         // set margin in millimeters
         MarginMeasureType = MeasureType.Percents,
         Margin = new Padding() { Left = 1, Top = 1, Right = 1 },
     };
     // sign document to file
     signature.Sign("signed.docx", options);
 }
