我正在尝试将存储在我的资产文件夹中的 pdf 转换为使用PdfViewer.jar
.
这是我的代码:
public static Bitmap renderToBitmap(InputStream inStream) {
Bitmap bitmap = null;
try {
byte[] bArray = IOUtils.toByteArray(inStream);
ByteBuffer buf = ByteBuffer.wrap(bArray);
PDFPage mPdfPage = new PDFFile(buf).getPage(0, true);
float width = mPdfPage.getWidth();
float height = mPdfPage.getHeight();
bitmap = mPdfPage.getImage((int) (width), (int) (height), null);
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
inStream.close();
} catch (IOException e) {
// do nothing because the stream has already been closed
}
}
return bitmap;
}
这段代码正在做我需要的。但是生成的位图质量很差。如何提高创建的位图质量?
