How to Save a PictureDrawable as a JPEG/PNG file in Android?

[Bosah Chude]

I have PictureDrawable that I wish to save as an image (JPEG/PNG) but I can't seem to find any information how to go about this. I tried this but it does not seem to work

PictureDrawable myDrawable = GetPictureDrawable();
Bitmap bitmap = Bitmap.createBitmap(200, 200, Bitmap.Config.ARGB_8888);
myDrawable.draw(new Canvas(bitmap));
bitmap.compress(CompressFormat.JPEG, 100, new FileOutputStream("/MyLocation/MyImage.jpg"));

What am I doing wrongly?

as PictureDrawable can be instanated usind a picture, it should be fairly possible to convert it back. 2D Graphics @ android Devguide[^] Documentation on android.graphics.PictureDrawable[^] That one states a function getPicture() that returns a Picture Documentation on android.graphics.Picture[^] that one has a function writeToStream() - should be worth some try? regards Torsten

I never finish anyth...

public static void savePic(Bitmap bitmap, String saveFilePath) throws Exception {
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(saveFilePath));
bitmap.compress(Bitmap.CompressFormat.JPEG, 80, bos);
bos.flush();
bos.close();
}

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

add in the file "AndroidManifest.xml" 3.

Bitmap bitmap=BitmapFactory.decodeResource(this.getResources(), R.drawable.g7);
try {
savePic(bitmap, "/mnt/sdcard/test.jpg");
} catch (Exception e) {
e.printStackTrace();
}

Your answer shows how to save a Bitmap to a the SDCard. However, my question was how to save a PictureDrawable to the memory card. I needed to know how to convert the PictureDrawable to a Bitmap.

private static Bitmap pictureDrawable2Bitmap(PictureDrawable pictureDrawable){
Bitmap bitmap=Bitmap.createBitmap(pictureDrawable.getIntrinsicWidth(),pictureDrawable.getIntrinsicHeight(), Config.ARGB_8888);
Canvas canvas=new Canvas(bitmap);
canvas.drawPicture(pictureDrawable.getPicture());
return bitmap;
}
