将EMF转换为PNG，结果不完美

Question

我正在尝试将EMF文件转换为PNG，成功了一半。使用这些代码，我可以从EMF创建PNG图片，但结果并不完美:与原始图片相比，它被"压缩"了。水平+在图片的右侧一些列的像素缺失。(不知怎么的好像被剪掉了，不知道为什么)

任何想法?

我代码:

File f = new File(PathToImage);
try (FileInputStream fis = new FileInputStream(f)) {
HemfPicture emf = new HemfPicture(fis);
Dimension2D dim = emf.getSize();
int width = Units.pointsToPixel(dim.getWidth());
int height = Units.pointsToPixel(dim.getHeight());
BufferedImage bufImg = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
Graphics2D g = bufImg.createGraphics();
g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
g.setRenderingHint(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
g.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BICUBIC);
g.setRenderingHint(RenderingHints.KEY_FRACTIONALMETRICS, RenderingHints.VALUE_FRACTIONALMETRICS_ON);
emf.draw(g, new Rectangle2D.Double(0, 0, width, height));
g.dispose();
ImageIO.write(bufImg, "PNG", new File(
path + imageName + ".png"));
}

问题是我使用了旧版本的Apache POI。我尝试了Apache POI 5.0.0，结果要好得多。

Maven:

<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>5.0.0</version>
</dependency>
