在我的应用中,用户从相机或图库中获取图像,然后将这些图像转换为PDF 现在我的问题是在某些设备上,相机捕获的图像旋转了90度,这些设备是一些三星设备,特别是S7,
这是我调用所选图像并将其转换为PDF的地方
PdfDocument document=new PdfDocument();
// crate a page description
PdfDocument.PageInfo pageInfo;
PdfDocument.Page page;
Canvas canvas;
int i;
Bitmap image;
for (i=0; i < list.size(); i++) {
pageInfo=new PdfDocument.PageInfo.Builder(992, 1432, 1).create();
page=document.startPage(pageInfo);
canvas=page.getCanvas();
image=BitmapFactory.decodeFile(list.get(i));
image = Bitmap.createScaledBitmap(image, 980, 1420, true);
image.setDensity(DisplayMetrics.DENSITY_300);
canvas.setDensity(DisplayMetrics.DENSITY_300);
canvas.drawBitmap(image, 0, 0, null);
document.finishPage(page);
}
@SuppressWarnings("deprecation") String directory_path=Environment.getExternalStorageDirectory().getPath() + "/mypdf/";

@SuppressLint("SimpleDateFormat") String timeStamp=(new SimpleDateFormat("yyyyMMdd_HHmmss")).format(new Date());
String targetPdf=directory_path + timeStamp + ".pdf";
File filePath=new File(targetPdf);
try {
document.writeTo(new FileOutputStream(filePath));
} catch (IOException e) {
Log.e("main", "error " + e.toString());
Toasty.error(this, "Error making PDF" + e.toString(), Toast.LENGTH_LONG).show();
}
// close the document
document.close();
