Ive been searching all ove on how to edit a image and save it. The
only way i have come accross other than just changing the size or
orientation is to use canvas. Now canvas works fine but i cannot seem
to save the newley created image.. the image always returns the
original image.
@Override protected void onDraw(Canvas canvas) {
FileInputStream in = null;
try {
in = new FileInputStream("myimage.jpg");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Bitmap bitmapOrg = BitmapFactory.decodeStream(in);
int wd = bitmapOrg.getWidth();
int hd = bitmapOrg.getHeight();
canvas.drawBitmap(bitmapOrg, 0, 0, null);
canvas.drawBitmap(bitmapOrg, wd, 0, null);
canvas.drawBitmap(bitmapOrg, 0, hd, null);
canvas.drawBitmap(bitmapOrg, wd, hd, null);
canvas.save();
FileOutputStream fos = null;
try {
fos = new FileOutputStream("/sdcard/test.png");
} catch (FileNotFoundException e) {
e.printStackTrace();
}
bitmapOrg.compress(Bitmap.CompressFormat.PNG, 50, fos);
try {
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
