Overview A CSS property transition on an element is hardware-accelerated if all these conditions are met: Hardware-accelerated layer compositing is enabled in the browser The CSS property being transitioned is acceleratable The element has been given its own compositing layer Generally, the requirements for these conditions are: The relevant hardware-acceleration options must be enabled, and … Read more
Instead of allocating a new canvas on each repaint, you should be able to allocate it once and then reuse the canvas on each repaint. on init and on resize: Bitmap b = Bitmap.createBitmap(getWidth(), getHeight(), Bitmap.Config.ARGB_8888); Canvas c = new Canvas(b); on repaint: b.eraseColor(Color.TRANSPARENT); // needed if backColor is not opaque; thanks @JosephEarl c.drawColor(backColor); c.drawCircle(cx, … Read more
To answer the above question, let me introduce few concepts related to Android OpenMAX Android uses OpenMAX for codec interface. Hence all native codecs (hardware accelerated or otherwise) provide OpenMAX interface. This interface is used by StageFright(Player framework) for decoding media using codec NDK Android allows Java Applications to interact with underlying C/C++ native libraries … Read more
add: -webkit-backface-visibility: hidden; -webkit-perspective: 1000; backface-visibility: hidden; perspective: 1000; if you working with 3d transform.. it is a cheap trick BUT it will improve the performance espacially on iPad.. furthermore you can try to -webkit-transform: rotateZ(0deg); AFAIK rotations can boost the performance because gpu´s are much better in rotating something.. another way is to lay … Read more
To use or not to use It is advised to use hardware acceleration only if you have complex custom computations for scaling, rotating and translating of images, but do not use it for drawing lines or curves (and other trivial operations) (source). If you plan on having common transitions and also given that you have … Read more
I found the most effective fix for this, first mentioned here, was to set a transparent background color after the layout has been inflated: webView.setBackgroundColor(Color.argb(1, 0, 0, 0)); Yes, it’s a total hack, but it’s the only solution I’ve found to work well without disabling hardware acceleration. Note that this does not work through setting … Read more
Currently the minimum limit is 2048px (i.e. the hardware must support textures at least 2048×2048.) In ICS we will introduce a new API on the Canvas class that will give you this information: Canvas.getMaximumBitmapWidth() and Canvas.getMaximumBitmapHeight().
After some investigation I was able to implement the necessary HW accelerated decoding on OS X (VDA) and Linux (VDPAU). I will update the answer when I get my hands on Windows implementation as well. So let’s start with the easiest: Mac OS X To get HW acceleration working on Mac OS you should just … Read more
A. In an imperative programming language, statements are executed in sequence, and each statement may change the program’s state. So analyzing translation units is inherently sequential. An example: Check out how constant propagation might work – a = 5; b = a + 7; c = a + b + 9; You need to go … Read more
