   if err != nil {
   	log.CErrorln(c,"Get file error, ", err)
   	return err
   }
   log.Println(file)
   //image, err := file.Open()
   //if err != nil {
   //	log.CErrorln(c, "Open file error, ", err)
   //	return err
   //}
   src, err := imaging.Open(file.Filename)
   if err != nil {
   	log.CErrorln(c, "Open file error, ", err)
   	return err
   }
   
   src = imaging.Resize(src, 200, 0, imaging.Lanczos)
   
   // Save the resulting image as JPEG.
   err = imaging.Save(src, "testdata/out_example.jpg")

   Hi,

   What type is c in your example?

   file, err := c.FormFile("file")
   

   The FormFile method of http.Request from standard library returns a multipart.File (https://pkg.go.dev/net/http#Request.FormFile). You can pass it to imaging.Decode to decode the image.
