Photoview: No method to retain zoom level when image is changed

[usmanrana07]

If we show thumbnail in ImageView and user zooms the views, then when we load the actual image in ImageView the zoom value resets. There should be a method to retain the zoom state.

My app has a image filter effect feature, after the image is applied a filter effect and set to photoview, the zoom level is reset. Need to retain zoom level.

Just found how to do it:

if (!resetMatrix){
        val matrix = Matrix()
        photoView.getSuppMatrix(matrix)
        photoView.setImageBitmap(filteredBitmap)
        photoView.setSuppMatrix(matrix)
}
else {
    photoView.setImageBitmap(filteredBitmap)
}
