Scaled Bitmap maintaining aspect ratio

This will respect maxWidth and maxHeight, which means the resulting bitmap will never have dimensions larger then those:

 private static Bitmap resize(Bitmap image, int maxWidth, int maxHeight) {    if (maxHeight > 0 && maxWidth > 0) {        int width = image.getWidth();        int height = image.getHeight();        float ratioBitmap = (float) width / (float) height;        float ratioMax = (float) maxWidth / (float) maxHeight;        int finalWidth = maxWidth;        int finalHeight = maxHeight;        if (ratioMax > ratioBitmap) {            finalWidth = (int) ((float)maxHeight * ratioBitmap);        } else {            finalHeight = (int) ((float)maxWidth / ratioBitmap);        }        image = Bitmap.createScaledBitmap(image, finalWidth, finalHeight, true);        return image;    } else {        return image;    }}

What about this:

Bitmap background = Bitmap.createBitmap((int)width, (int)height, Config.ARGB_8888);float originalWidth = originalImage.getWidth(); float originalHeight = originalImage.getHeight();Canvas canvas = new Canvas(background);float scale = width / originalWidth;float xTranslation = 0.0f;float yTranslation = (height - originalHeight * scale) / 2.0f;Matrix transformation = new Matrix();transformation.postTranslate(xTranslation, yTranslation);transformation.preScale(scale, scale);Paint paint = new Paint();paint.setFilterBitmap(true);canvas.drawBitmap(originalImage, transformation, paint);return background;

I added a paint to filter the scaled bitmap.

here is a method from my Utils class, that does the job:

public static Bitmap scaleBitmapAndKeepRation(Bitmap targetBmp,int reqHeightInPixels,int reqWidthInPixels)    {        Matrix matrix = new Matrix();        matrix .setRectToRect(new RectF(0, 0, targetBmp.getWidth(), targetBmp.getHeight()), new RectF(0, 0, reqWidthInPixels, reqHeightInPixels), Matrix.ScaleToFit.CENTER);        Bitmap scaledBitmap = Bitmap.createBitmap(targetBmp, 0, 0, targetBmp.getWidth(), targetBmp.getHeight(), matrix, true);        return scaledBitmap;    }
