I want to make a mirrored/reversal bitmap from the original bitmap source. But I know only a way of copying pixel by pixel.
Is there a easy/fast way to make a mirrored/reversal bitmap?

View 2 Replies View RelatedGranted I am in the middle of my office building, so I only get 1 bar. But from speedtest.net my Droid Incredible only had a download speed of 0.32 Mbps and and an upload speed of 0.13 Mbps (Ping was 410ms). This is just awful, granted it is only 3g. I am interested to see what other people get. Oh, and please don't post speed tests if you are on Wifi, I am only interested in the mobile broadband connection.
View 19 Replies View RelatedI would like to be able to use OpenGL in the Android to render into a bitmap (or any other sort of buffer I can turn into one), without actually displaying a GLSurfaceView.
The purpose is to dynamically create very complex images using OpenGL, and then drawing those images on the canvas of a MapView.
I have tried overlaying a translucent GLSurfaceView over a MapView, my preferred approach, but it has some problems:
1) I have complex menus I need to display from either the MapView or the GLSurfaceView. I have been doing this using a ListView with its own activity. Unfortunately, that activity pushes the MapView down the stack. The result is a bit of flickering when the ListView activity finishes, popping the MapView back to the top. Even worse, if I use the ListView to overlay the GLSurfaceView (giving it the same complex menu capabilities), when it finishes, the GLSurfaceView reappears but the MapView doesn't display.
2)As soon as the GLSurfaceView is created, the MapView stops fetching and rendering tiles. There seems to be no way to know when the MapView is complete, so I have to delay an arbitrary interval before creating the surfaceview.
3) When the GLSurfaceView is present, the MapView's built-in user interface functions are obscured.
Anyone know if there is a way around any of these problems?
It didn't take me long to realize update.zip installations of ROMs don't always work like they should, meaning the only way to install a ROM is via Nandroid restore. But, that clears all my data with it, meaning I have to re-DL and reconfigure all my app and settings. But with new ROM versions coming out every day, going through this process of repeat-reconfiguration is starting to become a major hassle. What options are there for avoiding this headache?
View 20 Replies View RelatedI have some images that I loaded from a remote source stored in Bitmap variables and I want to display them. In addition to switching between these images the user should also be able to zoom and pan them. My first idea was to somehow pass them via an intent to the built-in gallery application but this doesn't seem to be possible.
A solution that is suggested in several places is using a WebView since it already supports zooming and panning.
My question is how does my Bitmap data get into the WebView? Do I have to write it to a file first, which I would have to remove again later, or is there an easier way?
Or are there even better ways to accomplish my main goal, which is displaying Bitmap data as zoomable and panable images?
I have an android application to display an image on another. the second image's white color should be converted in to transparent. so i used two imageviews. the original image to be overlayed is bitmap1. image after making transparent is bitmap2. when i run this i got some exceptions atsetPixel method. the code ...

What i mean is, after i take the picture, not the before image of me on the cell phone, the after image effect. I dont see any options to change this either. Its almost as if it changed settings itself.
View 2 Replies View RelatedSo I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file
View 1 Replies View RelatedI 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?
I 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.
I have two questions actually:
Is it better to draw an image on a bitmap or create a bitmap as resource and then draw it over a bitmap? Performance wise... which one is better?
If I want to draw something transparent over a bitmap, how would I go about doing it?
If I want to overlay one transparent bitmap over another, how would I do it?
My goal is the draw a bitmap onto another bitmap but rotated 90 degress. whats the most efficient way to do that. My current method is as follows which is horribly bad because it creates a new bitmap every time.

View 5 Replies View RelatedNew to Motorola droid. I was wondering if there is a shortcut to show you what apps/tasks you have running, and allows you to easily switch between them? Currently, I just hit the home button to get out of one app/task and then switch to the screen with the app I want, and click on the app/task. I imagine there is an easier way via a key or shortcut that will pop up my open apps and allow me to choose which one to go to. I figure with all the talk of the droid being a multitasker, I figure there would be an easy way to switch between tasks.

Is there any easy way to answer a call? I just got my first android (4.2) phone and find it a complicated procedure to answer calls.
When I get an incoming call I get a white phone symbol which I have to press and hold to get the red and green phone symbols to appear and to answer a call the timing has to be exact as if I release the white phone symbol before I have started the slide to answer it fails and I find it about impossible to reject a call with this method.
I thought there might be some setting to alter this like the lock screen but can't find anything.
With my old dumb phone I was able to set a timed alarm in just a few button presses.

All the alarm clock apps I've looked at seem to take a lot of time to set an alarm, or only do countdown timers.
