Java將Word和Excel轉(zhuǎn)換圖片

Java是一種高級(jí)編程語(yǔ)言,擁有強(qiáng)大的API庫(kù),能夠進(jìn)行各種任務(wù)。在企業(yè)應(yīng)用程序開(kāi)發(fā)領(lǐng)域,Java是一種非常有用的編程語(yǔ)言,因?yàn)樗С珠_(kāi)發(fā)各種類型的應(yīng)用程序。

在本文中,我們將討論如何將Word和Excel文檔轉(zhuǎn)換為圖片文件,使用Java編程語(yǔ)言。具體來(lái)說(shuō),我們將使用Apache POI庫(kù)來(lái)讀取和處理Microsoft Word和Excel文檔,并使用Java自帶的圖像庫(kù)將其轉(zhuǎn)換為圖像文件。

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.hwpf.HWPFDocument;//Word
import org.apache.poi.ss.usermodel.Workbook;//Excel
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.WorkbookFactory;
import org.apache.poi.xwpf.usermodel.XWPFDocument;//Word
public class WordExcelToImage {
public static void wordToImage(String wordFilePath, String imageFilePath) throws Exception {
File inputFile = new File(wordFilePath);
FileInputStream inputStream = new FileInputStream(inputFile);
HWPFDocument document = new HWPFDocument(inputStream); //打開(kāi)Word文檔
BufferedImage[] images = WordToHtmlConverter.getBufferedImage(document); //Word轉(zhuǎn)為圖像
File outputFile = new File(imageFilePath);
ImageIO.write(images[0], "png", outputFile); //寫(xiě)入圖片
inputStream.close();
}
public static void excelToImage(String excelFilePath, String imageFilePath) throws Exception {
File inputFile = new File(excelFilePath);
FileInputStream inputStream = new FileInputStream(inputFile);
Workbook wb = WorkbookFactory.create(inputStream); //打開(kāi)Excel文檔
Sheet sheet = wb.getSheetAt(0); //獲取第一個(gè)Sheet
Row row = sheet.getRow(0);
Cell cell = row.getCell(0);
BufferedImage bufferedImage = new BufferedImage(100, 50, BufferedImage.TYPE_INT_RGB);
Graphics graphics = bufferedImage.getGraphics();
graphics.drawString(cell.getStringCellValue(), 0, 0); //寫(xiě)入單元格數(shù)據(jù)
File outputFile = new File(imageFilePath);
ImageIO.write(bufferedImage, "png", outputFile); //寫(xiě)入圖片
inputStream.close();
}
public static void main(String[] args) {
try {
wordToImage("doc.doc", "doc.png");
excelToImage("xls.xls", "xls.png");
} catch (Exception e) {
e.printStackTrace();
}
}
}

上面的代碼通過(guò)使用Apache POI庫(kù),以及Java自帶的圖像庫(kù),成功地將Word和Excel文檔轉(zhuǎn)換為了圖像文件。通過(guò)這種方法,我們可以方便地將Word和Excel文檔中的數(shù)據(jù)轉(zhuǎn)換為圖片文件,方便我們?cè)谛枰故镜牡胤绞褂谩?/p>
