示例:

This component rasterize the page to bitmap. Then you can convert it to other image format.

Example:

int page = 1;
int dpi = 200;
MuPDFLib.RenderType RenderType = RenderType.RGB;
bool rotateAuto = true;
string file = @"C:\test.pdf";
string password = ""; 

MuPDFLib.MuPDF pdfDoc = new MuPDFLib.MuPDF(file, password);

pdfDoc.Page = page;
if (picPDF.Image != null)
    picPDF.Image.Dispose();
Bitmap bm = pdfDoc.GetBitmap(0, 0, dpi, dpi, 0, RenderType,
                             rotateAuto, false, 0);
                
pdfDoc.Dispose();
