]RasterCachedMultipageImage.IsDigitalSigned method
Performs a fast check to determine if the image is digitally signed, using the provided password and threshold.
public override bool IsDigitalSigned(string password, int percentageThreshold = -1)
| Parameter | Type | Description |
|---|---|---|
| password | String | The password to check the signing. |
| percentageThreshold | Int32 | The threshold (in percentage)[0-100] that determines if the image is considered signed. If not specified, a default threshold (75) will be applied. |
Return Value
True if the image is signed, otherwise false.
Remarks
This method provides the fastest detection by leveraging !:GetSignPercentage. Once the extracted data meets the specified threshold, further extraction steps aimed at improving detection accuracy are skipped.
The result is true only if all pages in the multi-page image are recognized as signed; otherwise, the image is considered unsigned.
