A helper function to create a bitmap copy of an object. This can be used to convert vector objects, text or complex nested Sprite's to a flattened bitmap.
function makeBitmapCopy(displayObj:IBitmapDrawable, transparent:Boolean = false, bgColor:uint = 0x00000000, smooth:Boolean = true):Bitmap {

If you want to Download image as Bitmap using Picasso following code will help you:
Picasso.with(mContext)
.load(ImageUrl)
.into(new Target() {
@Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
// Todo: Do some...
<Image x:Name="MyImage" />
// Show image from web
MyImage.Source = new BitmapImage(new Uri("http://your-image-url.com"))
// Show image from solution
MyImage.Source = new Uri("ms-appx:///your-image-in-solution", UriKind.Absolute)
// Show image from file
...
private static final String TAG = "IntentBitmapFetch";
private static final String COLON_SEPARATOR = ":";
private static final String IMAGE = "image";
@Nullable
public Bitmap getBitmap(@NonNull Uri bitmapUri, int maxDimen) {
InputStream is = context.getConten...
To add a resource to the cache you must provide a key and the resource. First make sure that the value is not in the cache already
public void addResourceToMemoryCache(String key, Bitmap resource) {
if (memoryCache.get(key) == null)
memoryCache.put(key, resource);
}
To get a resource from the cache simply pass the key of your resource (String in this example)
public Bitmap getResourceFromMemoryCache(String key) {
memoryCache.get(key);
}
LRU Cache
The following example code demonstrates a possible implementation of the LruCache class for caching images.
private LruCache<String, Bitmap> mMemoryCache;
Here string value is key for bitmap value.
// Get max available VM memory, exceeding this amount will throw an
// OutOfMem...
CREATE BITMAP INDEX
emp_bitmap_idx
ON index_demo (gender);
Bitmap index is used when data cardinality is low.
Here, Gender has value with low cardinality. Values are may be Male, Female & others.
So, if we create a binary tree for this 3 values while searching it will have unnecessary ...
