<一个href=\"http://stackoverflow.com/questions/11292417/how-to-convert-pdf-to-image-in-android-using-pdfbox-getting-error-to-import-ja\">how将PDF转换为图像在android系统？使用PDFBOX得到错误导入java.awt中和的javax

我想使用此图片为PDF preVIEW，这是德code，我有

I want to use this image as a pdf preview, this is de code that I have

private Bitmap showPage(int page, float zoom) throws Exception {
    Bitmap b=null;
    try {

        mPdfPage = mPdfFile.getPage(page, true);
        float wi = mPdfPage.getWidth();
        float hei = mPdfPage.getHeight();


        RectF clip = null;

        Bitmap bi = mPdfPage.getImage((int)(wi*zoom), (int)(hei*zoom), clip, true, true);
        b=bi;

        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        b.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
        File f = new File(Environment.getExternalStorageDirectory()+ File.separator + "Firstpdf.jpg");
        f.createNewFile();
        FileOutputStream fo = new FileOutputStream(f);
        fo.write(bytes.toByteArray());
        Log.e("amit","Go to page bitmap______SAVE");

    } catch (Throwable e) {

    }

    return b;
}

但在这行

Bitmap bi = mPdfPage.getImage((int)(wi*zoom), (int)(hei*zoom), clip, true, true);

我得到这个错误

The method getImage(int, int, Rectangle2D, ImageObserver) in the type PDFPage is not applicable for the arguments (int, int, RectF, boolean, boolean)

谁能帮我？

非常感谢你！

推荐答案

该方法的getImage 需要4个参数，但你通过5.检查的文件，并提供正确的参数。

The method getImage requires 4 parameters but you have passed 5. Check the documentation and provide correct parameters.
