image-capture

hey guys i am using the following code to access camera from my application. The application is able to access the camera i have also added a button whose onclicklistener adds this line of code :- camera.takePicture(mShutterCallback, mPictureCallbackRaw, mPictureCallbackJpeg); Now i dont know what happens but the application gets stuck i have to force close it and then i can not even access the native camera application. I think it leaves the application without releasing the Camera object. Plus the image never gets saved. Code :- SurfaceHolder holder; SurfaceView surface; Camera camera;

I am using AVFoundation classes to implement a custom camera in my app. I am only capturing still images, not video. I have everything working but am stumped by something. I take into account the device orientation when a still image is captured and set the videoOrientation of the video connection appropriately. A code snippet: // set the videoOrientation based on the device orientation to // ensure the pic is right side up for all orientations AVCaptureVideoOrientation videoOrientation; switch ([UIDevice currentDevice].orientation) { case UIDeviceOrientationLandscapeLeft: // Not clear why but

I know how to capture a screenshot by using Robot, Windowtester or FEST. I also know how to read a pixel from the screen by using robot. int x = 10; int y = 10; Color px = getPixelColor(int x, int y); However, I don't know how to read a pixel from an image that is already captured. I'm planning to compare a current image, with an image from file. Lets say both are PNG. Are there any frameworks that I can use to compare images pixel by pixel? hughes Is this in Java? If so, you can use ImageIO.read( "yourImage.png" ) to get a BufferedImage . That will have a getData() method which will give you
