Locating signature on page with different measure units Leave feedback
On this page
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
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);
}
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);
}
