Thanks I got that to work however now reloading the image is causing a
problem
here is the code
Bitmap img = BitmapFactory.decodeFile(fName);
Log.i("display"," mute: " + img.isMutable() + " recycle: "
+ img.isRecycled() );
Matrix matrix = new Matrix();
float scale = Math.min( (800.0f / img.getHeight()) ,
(1170.0f / img.getWidth()));
matrix.postScale(scale, scale);
pictBMP = Bitmap.createBitmap(img, 0, 0,
img.getWidth(), img.getHeight(), matrix, true);
Log.i("display"," mute: " + pictBMP.isMutable() + "
recycle: " + pictBMP.isRecycled() + " " + scale + " " +
matrix.toString() );
image.setImageBitmap(pictBMP);
pictCanvas = new Canvas(pictBMP);
If I load the original I get
false false
true false 0.73452 [0.73452 0.0 0.0] [0.0
0.73452 0.0] [0.0 0.0 1.0]
When I load the saved Image I get
false false
false false 1.0 [1.0 0.0 0.0] [0.0 1.0 0.0]
[0.0 0.0 1.0]
which then cause the pictCanvas = new Canvas line to fail
Unable to start activity ComponentInfo{...Display}:
java.lang.IllegalStateException: Immutable bitmap passed to Canvas
constructor
Caused by: java.lang.IllegalStateException: Immutable bitmap passed to
Canvas constructor
Any Ideas why the one is mutable and the other not, they are simply
jpg files are they not ?

Ok,
Create a LayerDrawable object and keep adding to it Drawable objects
(LayerDrawable.setDrawableByLayerId (int id, Drawable drawable))
extracted from each of your stacked Views.

I don't have access to the bitmaps (I don't think)
I have access to the ImageView and the Canvas associated with the ImageView
Thanks again

Draw each of the bitmaps on one canvas in the ascending order from
deepest to topmost.

I have 4 ImageViews one stacked on top of the other all the same size,
each ImageView has it's own associated canvas that I can access.
Thus allowing me to view "layers" of a single image on screen.
I now wish to save this screen image to a file.
How can I merge the canvases into one image?
Thanks in advance
