I take picture and obtain a Bitmap (bitmap), when I take the picture there is an image I would like to stay on the top (bitmao2). So to save the picture with the image on it I use a canvas.
I found two ways of creating a Bitmap from a view. But once I do that, the view disappears and I can't use it anymore. How can I redraw the view after generating my bitmap?
I am making a drawing app such that user can choose to load pictures from the gallery and further draw on it.
I face some trouble with creation of my bitmap for a custom analog clock widget. When i use RGB_565 configuration the image is displaying properly, but it has no transparent background.
I need to draw an exact square 3x3 cm on the screen, you need the exact dimensions in any type of screen as design work.
The result in a Samsung Ace is 2.8 cm, the result is not exact.
Java...
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
float ld = 30 * metrics.densityDpi * (metrics.density/25.4f);
bitmap = Bitmap.createBitmap((i
I'm trying to render a XML layout to an OpenGL surface. That works correctly, and I can do 3D effects on the layout. But, when I try to update it and render it again, it does not work.
android.webkit.WebView has capturePicture() to capture the entire contents of the current WebView, but how would you do this for only a specific element on the webpage? For example, you might have many images and text elements positioned with CSS in a div.There may be many elements but I would just like to capture the div as it is rendered in the WebView.
I want to use this code in JNI, without going back to Java.
I already converted bitmap manipulation to JNI (thanks to other stackoverflow posters), but this seems more complicated because I do not understand how to call constructors.
Bitmap bmp;
bmp = ((BitmapDrawable)imgview.getDrawable()).getBitmap();
if (bmp == null || !bmp.isMutable())
Bitmap bmp = Bitmap.createBitmap(w, h, Config.ARGB_8
I am learning on canvas and bitmap with paths and currently working on a drawing app where user can draw paths freely on the extended view.
The app also allow allowing user to import bitmap as the background and draw on it.
