Java 在PDF中绘制形状(基于Spire.Cloud.SDK for Java)

E-iceblue 2020-07-13 10:45:00 阅读数:28 评论数:0 点赞数:0 收藏数:0

Spire.Cloud.SDK for Java提供了pdfPathApi接口可用于在PDF文档中绘制形状(或图形),如绘制线条形状drawLine()、绘制矩形形状drawRectanglef(),下面将介绍如何通过Java示例和步骤来实现:

一、导入jar文件。(有2种方式)

创建Maven项目程序,通过maven仓库下载导入。以IDEA为例,新建Maven项目,在pom.xml文件中配置maven仓库路径,并指定spire.cloud.sdk的依赖,如下:

<repositories>
<repository>
<id>com.e-iceblue</id>
<name>cloud</name>
<url>http://repo.e-iceblue.cn/repository/maven-public/</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId> cloud </groupId>
<artifactId>spire.cloud.sdk</artifactId>
<version>3.5.0</version>
</dependency>
<dependency>
<groupId> com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.8.1</version>
</dependency>
<dependency>
<groupId> com.squareup.okhttp</groupId>
<artifactId>logging-interceptor</artifactId>
<version>2.7.5</version>
</dependency>
<dependency>
<groupId> com.squareup.okhttp </groupId>
<artifactId>okhttp</artifactId>
<version>2.7.5</version>
</dependency>
<dependency>
<groupId> com.squareup.okio </groupId>
<artifactId>okio</artifactId>
<version>1.6.0</version>
</dependency>
<dependency>
<groupId> io.gsonfire</groupId>
<artifactId>gson-fire</artifactId>
<version>1.8.0</version>
</dependency>
<dependency>
<groupId>io.swagger</groupId>
<artifactId>swagger-annotations</artifactId>
<version>1.5.18</version>
</dependency>
<dependency>
<groupId> org.threeten </groupId>
<artifactId>threetenbp</artifactId>
<version>1.3.5</version>
</dependency>
</dependencies>

完成配置后,点击“Import Changes” 即可导入所有需要的jar文件。如果使用的是Eclipse,可参考这里的导入方法。

二、登录冰蓝云账号,创建文件夹,上传文档

三、创建应用程序,获取App ID及App Key

四、Java代码示例

【示例1】绘制线条形状

import spire.cloud.pdf.sdk.ApiException;
import spire.cloud.pdf.sdk.Configuration;
import spire.cloud.pdf.sdk.api.PdfPathApi;
public class DrawLine {
//配置账号信息
static String appId = "App ID";
static String appKey = "App Key";
static String baseUrl= "https://api.e-iceblue.cn";
static Configuration configuration = new Configuration(appId, appKey, baseUrl);
static PdfPathApi pdfPathApi = new PdfPathApi(configuration);
public static void main(String[] args) throws ApiException {
String name = "samplefile.pdf";//用于测试的PDF源文档
String outPath = "output/DrawLine.pdf";//结果文档路径(保存在冰蓝云端output文件夹下)
int pageNumber = 1;//指定需要绘制线段的PDF页面
float firstPointfX = 100;//指定线段起始点坐标
float firstPointfY = 150;
float secondPointfX = 400;
float secondPointfY = 150;
String folder = "input";//源文档输在文件夹
String storage = null;//冰蓝云提供的2G免费云存储空间
String password = null;//源文档密码(无密码设置为null)
//调用方法绘制线条
 pdfPathApi.drawLine(name, outPath, pageNumber, firstPointfX, firstPointfY, secondPointfX, secondPointfY, folder, storage, password);
}
}

线条绘制效果:

 

【示例2】绘制矩形形状

import spire.cloud.pdf.sdk.ApiException;
import spire.cloud.pdf.sdk.Configuration;
import spire.cloud.pdf.sdk.api.PdfPathApi;
import spire.cloud.pdf.sdk.model.RectangleF;
public class DrawRec {
//配置账号信息
static String appId = "App ID";
static String appKey = "App Key";
static String baseUrl= "https://api.e-iceblue.cn";
static Configuration configuration = new Configuration(appId, appKey, baseUrl);
static PdfPathApi pdfPathApi = new PdfPathApi(configuration);
public static void main(String[] args) throws ApiException {
String name = "samplefile1.pdf";//加载需要添加形状的PDF源文档
String outPath = "output/DrawRectanglef.pdf";//指定结果文档路径(保存在冰蓝云端output文件夹下)
int pageNumber = 1;//指定需要添加形状的PDF页面

RectangleF rect = new RectangleF();//创建RectangleF类的对象
rect.setX(100f);//指定形状坐标
 rect.setY(100f);
rect.setWidth(350f);//指定形状宽度、高度
 rect.setHeight(60f);
String folder = "input";//源文档所在文件夹
String storage = null;//冰蓝云提供的2G免费存储空间
String password = null;//源文档密码(无密码设置为null)
//调用方法绘制矩形
 pdfPathApi.drawRectanglef(name, outPath, pageNumber, rect, folder, storage, password);
}
}

矩形绘制效果:
