Getting Divide by Zero and Access Denied errors

Post by NoDozing »

We're converting PDF files to PNG files. We're getting An exception of type 'System.DivideByZeroException' occurred in Magick.NET-x86.dll but was not handled in user code if we use

Code: Select all

                    var s = new MagickReadSettings();
                    s.Density = new MagickGeometry(300, 300);

                    using (var images = new MagickImageCollection())
                    {
                        images.Read(inputPdfPath, s);
We get An unhandled exception of type 'System.AccessViolationException' occurred in Magick.NET-x86.dll if we use

Code: Select all

                    var s = new MagickReadSettings();
                    s.Density = new MagickGeometry(150, 150);

                    using (var images = new MagickImageCollection())
                    {
                        images.Read(inputPdfPath, s);
We get no errors if we use:

Code: Select all

                    var s = new MagickReadSettings();
                    s.Density = new MagickGeometry(75, 75);

                    using (var images = new MagickImageCollection())
                    {
                        images.Read(inputPdfPath, s);
I'd be happy to send the PDF file is needed. Some PDFs give no errors with the first code above.
