aspose.word文档格式转换
1. 简介
aspose.word文档格式转换非常方便，如果只有一份文件（如docx，pdf等）直接调用save方法即可。如果是多页的，我们可以借助SaveOptions 实现。如图片
ImageSaveOptions iso = new ImageSaveOptions(SaveFormat.JPEG);
iso.setResolution(300);
iso.setPrettyFormat(true);
iso.setUseAntiAliasing(true);
Document doc = new Document(docPath);
int pageCount = doc.getPageCount();
String imagesPath =String.format("%s/images", outFilePath);
File imagesDir = new File(imagesPath);
if(imagesDir.exists()){
imagesDir.mkdirs();
}
for (int i = 0;i<pageCount;i++){
PageSet pageSet = new PageSet(i);
iso.setPageSet(pageSet);
String mainName = FileUtil.mainName(docPath);
String outPath = String.format("%s/%s_%s.jpg",imagesDir,mainName,i+1);
doc.save(outPath,iso);
}
return imagesPath;
