When I try to create PDF, that contains Rectangle with bottom=0.0000610351563f output PDF become corrupted. Here is simplified example:
static void Main(string[] args)
{
var pdf = new Pdf();
var section = new Section();
var canvas = new Graph(section);
section.Paragraphs.Add(canvas);
var border = new Rectangle(canvas, 0, 0.0000610351563f, 100, 100);
canvas.Shapes.Add(border);
pdf.Sections.Add(section);
pdf.Save(@"C:\Temp\1.pdf");
}
