How To Resize Bimpat Size?

In my application I need to resize the bitmap to imageview size. I tried the following code and I am getting exception. Bitmap bmp = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(),

Solution 1:

Try with the following code

publicstaticBitmapresizeBitMapImage1(String filePath, int targetWidth,
            int targetHeight) {
        Bitmap bitMapImage = null;
        // First, get the dimensions of the imageOptions options = newOptions();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(filePath, options);
        double sampleSize = 0;
        // Only scale if we need to// (16384 buffer for img processing)Boolean scaleByHeight = Math.abs(options.outHeight - targetHeight) >= Math
                .abs(options.outWidth - targetWidth);

        if (options.outHeight * options.outWidth * 2 >= 1638) {
            // Load, scaling to smallest power of 2 that'll get it <= desired// dimensions
            sampleSize = scaleByHeight ? options.outHeight / targetHeight
                    : options.outWidth / targetWidth;
            sampleSize = (int) Math.pow(2d,
                    Math.floor(Math.log(sampleSize) / Math.log(2d)));
        }

        // Do the actual decoding
        options.inJustDecodeBounds = false;
        options.inTempStorage = new byte[128];
        while (true) {
            try {
                options.inSampleSize = (int) sampleSize;
                bitMapImage = BitmapFactory.decodeFile(filePath, options);

                break;
            } catch (Exception ex) {
                try {
                    sampleSize = sampleSize * 2;
                } catch (Exception ex1) {

                }
            }
        }

        return bitMapImage;
    }

Solution 2:

I think you are trying to get the width and height of the Bitmap itself, but instead you want to get the Height and Width of your ImageView and resize your Bitmap acordingly.

Solution 3:

Try this:

Bitmapbmp= Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), aMatrix, false);
bmp = Bitmap.createScaledBitmap(bmp, MyImageview_wt, MyImageview_ht, false);
MyImageview.setImageBitmap(bmp);
