I had the same problem trying to implement OpenCV. I was able to fix it by making the following changes to the deliverAndDrawFrame method. Rotate the canvas object Canvas canvas = getHolder().lockCanvas(); // Rotate canvas to 90 degrees canvas.rotate(90f, canvas.getWidth()/2, canvas.getHeight()/2); Resize the bitmap to fit entire size of canvas before drawing // Resize Bitmap … Read more
If the image(photo) was taken by a program made by you, you must set Parameters.setRotation with the correct rotation value. This, depending of camera drive, rotates the image before save or save the rotation value to exif TAG_ORIENTATION. Therefore, if TAG_ORIENTATION is null or zero, the image are in the correct orientation, otherwise you must … Read more
UPDATE: version v0.7.0 of the camera package introduced a breaking change for calculating camera aspectRatio and it seems they add the AspectRatio widget by default Well, inspired by previous posts, I got it to work on 2 screens with different screen aspect ratios. What I did was print the values and look for differences (not … Read more
What you’re doing is essentially what’s written in the TextureView docs, so it should work. The error message means that the “producer” side of the BufferQueue (the camera) grabbed a buffer, and is now trying to un-grab it (via cancelBuffer()). However, the “consumer” side (the SurfaceTexture) has gone away. Because the “consumer” side owns the … Read more
You can create bitmap with captured image as below: Bitmap bitmap = Bitmap.createScaledBitmap(capturedImage, width, height, true); Here you can specify width and height of the bitmap that you want to set to your ImageView. The height and width you can set according to the screen dpi of the device also, by reading the screen dpi … Read more
filePath.substring(filePath.lastIndexOf(“.”)); // Extension with dot .jpg, .png or filePath.substring(filePath.lastIndexOf(“.”) + 1); // Without dot jpg, png
In my case I was getting this error : getParameters failed (empty parameters) when I called getParameters() after unlocking the camera. So, please call getParameters() before you call camera.unlock().
I think I know what you are asking for. Here is what you can do. first get the height of the person say h meters. if you can calculate the height of the camera from ground (using height if the person i.e. h) and get angles A and B using gyroscope or something from android … Read more
Firstly, catch your exceptions in onPictureTaken, leaving empty catch sections is not a good practice. Then, I would add a flag that would prevent from calling takePicture() while previous picture is being saved. Later in your button onClick you would check if it’s ok to call takePicture(). Declare a flag as a member of your … Read more
you can make the parameter of camera, and then apply colorfilter to the parameter to get the different effect, but first you have to check the supported colorfilter for your device, basically it is device dependent. Camera.Parameters p = camera.getParameters(); camera.Parameters parameters = camera.getParameters(); //this will provide the supporting parameter for your device. p.setSceneMode(Camera.Parameters.FLASH_MODE_AUTO); //it … Read more
