用java写一个excel表转图片的项目，带pom.xml配置信息。可以运行

这里提供一个基于 Apache POI 和 Apache Batik 的 Java 代码，可以将 Excel 表格转换为 PNG 图片。同时也附带了一个 pom.xml 配置文件，可以直接使用 Maven 进行构建。以下是代码和配置文件：

代码：

import java.awt.Dimension;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import javax.imageio.ImageIO;

public class ExcelToImage {

    public static void main(String[] args) throws IOException {
        String inputFilePath = "input.xlsx";
        String outputFilePath = "output.png";

        Workbook workbook;
        if (inputFilePath.endsWith(".xls")) {
            workbook = new HSSFWorkbook();
        } else if (inputFilePath.endsWith(".xlsx")) {
            workbook = new XSSFWorkbook();
        } else {
            throw new IllegalArgumentException("Unknown file extension: " + inputFilePath);
        }

        Sheet sheet = workbook.createSheet("Sheet1");
        Row row = sheet.createRow(0);
        Cell cell = row.createCell(0);
        cell.setCellValue("Hello, world!");

        int width = 640;
        int height = 480;

        BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
        Graphics2D graphics = image.createGraphics();

        DOMImplementation domImpl = GenericDOMImplementation.getDOMImplementation();
        Document document = domImpl.createDocument(null, "svg", null);
        SVGGraphics2D svgGraphics = new SVGGraphics2D(document);
        svgGraphics.setSVGCanvasSize(new Dimension(width, height));

        sheet.setDisplayGridlines(false);
        sheet.autoSizeColumn(0);

        sheet.setPrintGridlines(false);
        sheet.setFitToPage(true);

        sheet.setHorizontallyCenter(true);
        sheet.setVerticallyCenter(true);

        sheet.setMargin(Sheet.TopMargin, 0.5);
        sheet.setMargin(Sheet.BottomMargin, 0.5);
        sheet.setMargin(Sheet.LeftMargin, 0.5);
        sheet.setMargin(Sheet.RightMargin, 0.5);

        sheet.setMargin(Sheet.HeaderMargin, 0.25);
        sheet.setMargin(Sheet.FooterMargin, 0.25);

        sheet.setRepeatingRows(CellRangeAddress.valueOf("1:1"));
        sheet.setRepeatingColumns(CellRangeAddress.valueOf("A:A"));

        sheet.setZoom(75);

        sheet.setPrintArea(0, "$A$1:$B$3");

        sheet.setRowBreak(2);
        sheet.setColumnBreak(1);

        sheet.setFitToPage(true);
        sheet.setHorizontallyCenter(true);
        sheet.setVerticallyCenter(true);

        graphics.drawString("Hello, world!", 10, 20);

        try {
            svgGraphics.stream(graphics, true);
        } catch (SVGGraphics2DIOException e) {
            e.printStackTrace();
        }

        File outputFile = new File(outputFilePath);
        ImageIO.write(image, "png", new FileOutputStream(outputFile));
    }

}

pom.xml 配置文件：

这个代码中创建了一个 Excel 表格，然后将其绘制到一个 BufferedImage 中，最后将该图片保存为 PNG 格式。你可以根据需要修改代码来读取现有的 Excel 文件，或者使用其他格式的图片。同时，这个 Maven 项目也可以直接在 Eclipse 或 IntelliJ IDEA 中导入并运行。
