How can i scale the gif?

[csshuai]

e.g. :
the gif image size: 1280 * 720,
how can i get a Bitmap with size (800 * 600)?

---

Just like this:
GifInfoHandle : {
width = 1280;
height = 720;
}

Bitmap buffer = Bitmap.createBitmap(800, 600, Bitmap.Config.ARGB_8888);
GifInfoHandle.renderFrame(buffer);

You can use something like this:

        Bitmap currentFrame = gifDrawable.getCurrentFrame();
        Bitmap scaledFrame = Bitmap.createScaledBitmap(currentFrame, 800, 600, true);

That used more memory. There are ways to save memory?

In GifTextureView you can use [TextureView#getBitmap(int, int)](http://developer.android.com/reference/android/view/TextureView.html#getBitmap%28int, int%29)
there is no internal bitmap in such case.

In GifDrawable I have no other ideas without modifying library source.
You can change #getCurrentFrame() implementation to not make a copy but return internal buffer directly.
Bitmap passed to #renderFrame() cannot be smaller than GIF dimensions unless you change native code.

Whether it will provide #renderFrame() to get smaller Bitmap function in the future?

I have no plan to do such feature myself, but pull requests are welcome.

You can use something like this:

        Bitmap currentFrame = gifDrawable.getCurrentFrame();
        Bitmap scaledFrame = Bitmap.createScaledBitmap(currentFrame, 800, 600, true);

Hey @koral--
Where should I write this code snippet to resize the gif???

Hey @koral--

I made a new class which extends your GifDrawable

    public MyGifDrawable(@NonNull File file, int width , int height) throws IOException {
        super(file);
        this.width = width;
        this.height = height;
        this.mDstRect = new Rect(0, 0, this.width, this.height);
    }

    @Override
    public void draw(@NonNull Canvas canvas) {
//        super.draw(canvas);
        Bitmap bmp = getCurrentFrame();
        Rect mSrcRect = new Rect(0, 0, this.width, this.height);
        Bitmap scaledFrame = Bitmap.createScaledBitmap(bmp, this.width, this.height, true);
        canvas.drawBitmap(scaledFrame, mSrcRect, this.mDstRect, mPaint);
    }

It looks like this. I am unable to fulfil my needs actually. My code can only resize the image.
How should I resize the canvas?
