Question

您好我正在创建一个条形码，但是当我创建一个代码时，这会返回一个AwtImage，当我尝试解析到itextpdf.text.Image时，这会让我出错并且无法编译mi代码这是我的条形码生成器

import com.itextpdf.barcodes.Barcode128;
import com.itextpdf.text.Image;
import java.awt.Color;
import java.io.FileNotFoundException;

public Image getImage(){
        try{
            Barcode128 code128 = new Barcode128(null);
            code128.setCode("P662130002");
            code128.setBarHeight(80f);
            java.awt.Image awtImage = code128.createAwtImage(Color.WHITE, Color.BLACK);
            Image img = Image.getInstance(awtImage);
            return img;
        }catch(Exception e){
            return null;
        }
    }

这是我的maven依赖

我解决了这个问题你必须加一个额外的参数，这个代码是下一个

import com.itextpdf.barcodes.Barcode128;
import com.itextpdf.text.Image;
import java.awt.Color;
import java.io.FileNotFoundException;

public Image getImage(){
        try{
            Barcode128 code128 = new Barcode128(null);
            code128.setCode("P662130002");
            code128.setBarHeight(80f);
            java.awt.Image awtImage = code128.createAwtImage(Color.WHITE, Color.BLACK);
            Image img = Image.getInstance(awtImage);
            return img;
        }catch(Exception e){
            return null;
        }
    }

java.awt.Image到itextpdf.text.Image不起作用
