The LEADTOOLS CloudServices library provides developers with a simple and streamlined way to verify input files by using the VerificationEngine class. The VerficationEngine constructor takes the following parameters:

maxElements - The maximum number of SVG elements to verify. The verification method will return false if more elements exist.
maxWidth - The maximum width of the input. The verification method will return false if the width is larger than the specified value.
maxHeight - The maximum height of the input. The verification method will return false if the height is larger than the specified value.
supportImages- List of supported RasterImageFormats. Passing null indicates that the method will check all RasterImageFormats.

Code:


         int MaxSVGElements = 30000;
         int MaxRasterWidth = 30000;
         int MaxRasterHeight = 30000;

         var inputStream = File.Open(@"leadtools.pdf", FileMode.Open);
         VerificationEngine verificationEngine = new VerificationEngine(MaxSVGElements, MaxRasterWidth, MaxRasterHeight, null);

         if (verificationEngine.VerifyInput(inputStream, true, null))
            Console.WriteLine("Verified");
         else
            Console.WriteLine("Verification Failed");
