It’s an inlined image (png), encoded in base64. It can make a page faster: the browser doesn’t have to query the server for the image data separately, saving a round trip. (It can also make it slower if abused: these resources are not cached, so the bytes are included in each page load.)
The Bitmap class is an implementation of the Image class. The Image class is an abstract class; The Bitmap class contains 12 constructors that construct the Bitmap object from different parameters. It can construct the Bitmap from another bitmap, and the string address of the image. See more in this comprehensive sample.
use the android:background attribute in your xml. Easiest way if you want to apply it to a whole activity is to put it in the root of your layout. So if you have a RelativeLayout as the start of your xml, put it in here: <?xml version=”1.0″ encoding=”utf-8″?> <RelativeLayout xmlns:android=”http://schemas.android.com/apk/res/android” android:id=”@+id/rootRL” android:orientation=”vertical” android:layout_width=”fill_parent” android:layout_height=”fill_parent” android:background=”@drawable/background”> … Read more
The approach with stream is not correct. See here https://stackoverflow.com/a/8701748/355264 Correct code from above link: Image img; using (var bmpTemp = new Bitmap(“image_file_path”)) { img = new Bitmap(bmpTemp); }
As with many things in life, different people have different ideas about what is best. If you ask a landscape photographer who wanders around in the rain in Scotland’s mountains which is the best camera in the world, he’s going to tell you a light-weight, weather-sealed camera. Ask a studio photographer, and he’ll tell you … Read more
First off, in order to have any image “resize” to fit a picturebox, you can set the PictureBox.SizeMode = PictureBoxSizeMode.StretchImage If you want to do clipping of the image beforehand (i.e. cut off sides or top and bottom), then you need to clearly define what behavior you want (start at top, fill the height of … Read more

You can use the painterResource function: Image(painterResource(R.drawable.ic_xxxx),”content description”) The resources with the given id must point to either fully rasterized images (ex. PNG or JPG files) or VectorDrawable xml assets. It means that this method can load either an instance of BitmapPainter or VectorPainter for ImageBitmap based assets or vector based assets respectively. Example: Card( … Read more
rgb = np.dstack((r,g,b)) # stacks 3 h x w arrays -> h x w x 3 To also convert floats 0 .. 1 to uint8 s, rgb_uint8 = (np.dstack((r,g,b)) * 255.999) .astype(np.uint8) # right, Janna, not 256
You may try below. The function will keep the aspect rate of the original image. def image_resize(image, width = None, height = None, inter = cv2.INTER_AREA): # initialize the dimensions of the image to be resized and # grab the image size dim = None (h, w) = image.shape[:2] # if both the width and … Read more
