Android :: Resize Large Bitmap File To Scaled Output File
Jul 26, 2010I have a large bitmap (say 3888x2592) in a file. Now, I want to resize that bitmap to 800x533 and save it to another file.I normally would scale the bitmap by calling Bitmap.createBitmap method but it needs a source bitmap as the first argument, which I can't provide because loading the original image into a Bitmap object would of course exceed the memory (see here, for example).Is there a way to read a large image file with 10MP or more and save it to a new image file, resized to a specific new width and height, without getting an OutOfMemory exception?I also tried BitmapFactory.decodeFile(file, options) and setting the Options.outHeight and Options.outWidth values manually to 800 and 533, but it doesn't work that way.
View 4 Replies View RelatedAndroid : Crop Bitmap Without Reading Entire Bitmap / Cannot Read Image Into Memory
Jul 21, 2010I have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.
Uri data = getIntent().getData();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);
Any help would be great?
Android :: Create Mutable Bitmap From Camera - Draw Another Bitmap On Top - And Save It
Apr 2, 2009I am 1) taking a picture and 2) then draw another Bitmap on top of it 3) then I store it
I am doing it as follows and it works on the emulator.
On the device I get a OutOfMemoryError: bitmap size exceeds VM budget android.graphics.Bitmap.nativeCopy(Native Method) android.graphics.Bitmap.copy(Bitmap.java:199) in the line copy the Bitmap to get a mutable Bitmap.
CODE:...........
What I am asking:
a) Is there a better way to do what I am doing? 1) take a picture 2) draw another Bitmap on top of it 3) then I store it
b) What is the best way to create a mutable Bitmap from the picture I just took with the camera?
In my app, resolution is not an issue. If it works better for small photos that would be fine.

View 1 Replies View RelatedAndroid :: Resize Based On Orientation.
Feb 12, 2009I need to have my view resize itself based on the orientation. After extensive googling (maybe i was using the wrong terms) I could find nothing telling me how to detect when the orientation was changed. Here is my layout file: how do I have it automatically resize itself? I want each item (the EditText and the WebView) to fill half the screen (not counting the title/notification bars). I set the height to absolute and not wrap_content because wrap_content defaults to 1 line for EditText and nothing for WebView. and fill_parent has the EditText on top of the WebView.

View 3 Replies View RelatedAndroid : How To Detect A Layout Resize?
Nov 13, 2010Dianne Hackborn mentioned in a couple threads that you can detect when a layout as been resized, for example, when the soft keyboard opens or closes. Such a thread is this one... http://groups.google.com/group/android-developers/browse_thread/thread/d318901586313204/2b2c2c7d4bb04e1b However, I didn't understand her answer: "By your view hierarchy being resized with all of the corresponding layout traversal and callbacks." Does anyone have a further description or some examples of how to detect this? Which callbacks can I link into in order to detect this?

View 2 Replies View RelatedAndroid :: Virtual Keyboard - Resize All Popups Etc
May 22, 2009We have got all our own edit boxes etc. so we call the virtual keyboard from SDK 1.5 in the followng way (when the use selects one of our edit/text boxes):
Context c = getApplicationContext(); InputMethodManager inputManager = (InputMethodManager) c.getSystemService( Context.INPUT_METHOD_SERVICE ); inputManager.showSoftInput(ourCanvasInstance, 0);
This works fine and even populates our edit boxes automatically upon key entry, we can dismiss it by calling:
inputManager.toggleSoftInput(0, 0);
The problem we have now is that we need to know the size of the virtual keyboard so that we can resize all our popups etc to fit within the area of the screen that is not covered by the virtual keyboard. Is there anyway of getting the height of the default virtual keyboard? I have noticed that android.inputmethodservice.Keyboard has access to the height but I can't seem to find anyway to access this, does anyone happen to know any useful pointers to be able to access the height of the VK?
