问题
I have iTextSharp creating a pdf for me in VB.net. Everything was working famously, except now I want to embed an image. I tried this:
Dim test = My.Resources.MyImage
Dim logo = Image.GetInstance(test)
This an error though:
'GetInstance' cannot be called with these arguments
It appears as though it expects a path, and is getting a System.Drawing.Bitmap type.
Is there any way that I can add a project resource image to my PDF? Thanks in advance!
回答1:
One of the overloads for iTextSharp.text.Image.GetInstance() takes an System.Drawing.Image, so convert your PNG resource into this type and then use this overload. Something like this:
Dim test As System.Drawing.Image = System.Drawing.Image.FromHbitmap(My.Resources.MyImage.GetHbitmap())
Dim logo As iTextSharp.text.Image = iTextSharp.text.Image.GetInstance(test, System.Drawing.Imaging.ImageFormat.Png)
