I'm attempting to use Spire.PDF with Unity.. I've installed the free evaluation version spire.pdf-fe_4.3 and copied sprire.pdf.dll and spire.licence.dll from the NET 3.5 directory to my assets directory.
I'm using the following code for testing...
- Code: Select all
using Spire.License; // Not sure if this is needed but makes no difference to my error
using Spire.Pdf;
using Spire.Pdf.Graphics;
using System.Drawing;
public class SavePDF : MonoBehaviour
{
public void savePDF()
{
pdfTest();
}
void pdfTest()
{
PdfDocument doc = new PdfDocument();
PdfSection section = doc.Sections.Add();
PdfPageBase page = doc.Pages.Add();
//Load a tiff image from system
PdfImage image = PdfImage.FromFile("c:/users/Alex/Desktop/Logo.png");
//Set image display location and size in PDF
float widthFitRate = image.PhysicalDimension.Width / page.Canvas.ClientSize.Width;
float heightFitRate = image.PhysicalDimension.Height / page.Canvas.ClientSize.Height;
float fitRate = Mathf.Max(widthFitRate, heightFitRate);
float fitWidth = image.PhysicalDimension.Width / fitRate;
float fitHeight = image.PhysicalDimension.Height / fitRate;
page.Canvas.DrawImage(image, 30, 30, fitWidth, fitHeight);
doc.SaveToFile("c:/users/Alex/Desktop/Test.pdf");
doc.Close();
}
}
but as soon as pdfTest() is triggered I get the following error...
- Code: Select all

Spire.Pdf.PdfDocumentBase.ᜀ ()
Spire.Pdf.Pdf
Any idea what might be causing this issue? Do I need to manually set a licence file location?
Many thanks!
