Example 8 with RenderScript

use of android.support.v8.renderscript.RenderScript in project T-MVP by north2016.

the class BlurTransformation method transform.

/**
     * Transforms the given {@link Bitmap} based on the given dimensions and returns the transformed
     * result.
     * <p/>
     * <p>
     * The provided Bitmap, toTransform, should not be recycled or returned to the pool. Glide will automatically
     * recycle and/or reuse toTransform if the transformation returns a different Bitmap. Similarly implementations
     * should never recycle or return Bitmaps that are returned as the result of this method. Recycling or returning
     * the provided and/or the returned Bitmap to the pool will lead to a variety of runtime exceptions and drawing
     * errors. See #408 for an example. If the implementation obtains and discards intermediate Bitmaps, they may
     * safely be returned to the BitmapPool and/or recycled.
     * </p>
     * <p/>
     * <p>
     * outWidth and outHeight will never be {@link Target#SIZE_ORIGINAL}, this
     * class converts them to be the size of the Bitmap we're going to transform before calling this method.
     * </p>

     *                    return intermediate {@link Bitmap}s used in this transformation. For every
     *                    {@link Bitmap} obtained from the pool during this transformation, a
     *                    {@link Bitmap} must also be returned.
     * @param toTransform The {@link Bitmap} to transform.
     * @param outWidth    The ideal width of the transformed bitmap (the transformed width does not need to match exactly).
