轉jpg範例

PdfDocument pdfDoc = new PdfDocument(pdf_file);
int count = pdfDoc.getPageCount();
int zoom = 1;

for(int i=0;i < count ;i++){
     PageRenderer render = new PageRenderer(pdfDoc.getPage((i+1)), zoom, Page.PAGE_ROTATE_AUTO, ImageType.IMAGE_TYPE_RGB);
     render.setAntiAliasLevel(8);//需設為8，不然中文字會變醜
     render.render(true);

     JPGOptions options = new JPGOptions();
     options.setQuality(96);

     FileOutputStream out = new FileOutputStream(new File(out_dir+(i+1)+".jpg"));
     JimiWriter writer = Jimi.createJimiWriter("image/jpeg", out);
     writer.setSource(render.getImage().getSource());
     writer.setOptions(options);
     writer.putImage(out);
    
     out.flush();out.close();
    
     render.dispose();
}

pdfDoc.dispose();
