Hi All
I have the following problem, when executed this code.
imageView.setDrawingCacheEnabled(true);
Bitmap myBitmap = imageView.getDrawingCache();
ColorMatrix colorMatrix = new ColorMatrix();
colorMatrix.setSaturation(0);
Paint paint = new Paint();
ColorMatrixColorFilter cmcf = new
ColorMatrixColorFilter(colorMatrix);
paint.setColorFilter(cmcf);
Bitmap blackAndWhiteBitmap =
Bitmap.createBitmap(myBitmap.getWidth(),myBitmap.getHeight(),
Bitmap.Config.ARGB_8888);
Canvas drawingCanvas = new Canvas(blackAndWhiteBitmap );
drawingCanvas.drawBitmap(myBitmap, 0, 0, paint);
imageView.setImageBitmap(blackAndWhiteBitmap);
imageView.setDrawingCacheEnabled(false);
flagColor= false;
It code is for convert the ImageView to gris scala , and the question is if
exist some way from return the image in your correct colors
I can make the copy from Bitmap with these code before the converting the
image to gris scala and after make the restore
bitmap = myBitmap.copy(Bitmap.Config.ARGB_8888, true);
but if the image is reduced or enlarged, and want restored to correct color,
the image lose these changes.
Exist some way from that with the copy prior from the Image, can captured
your colors and after set these colors to new image changed
Thanks
David
