aspect-ratio

One of the device screen properties that Android lets an app query is it's aspect ratio. In the examples that I have seen this property seems to have only two values - long and notlong . I am trying to reverse engineer the logic being used by Android to classify a device as having one of the two aspect ratios. To get some official data to work with, I referred to the values provided by the device definitions included in the AVD Manager tool in Android Studio, and combined that with my own calculations: The column "Published Ratio" shows the value extracted from the AVD Manager. Based on these

Device Nexus 4 Android ver: 4.2.2 Hoping someone else has found this and can explain how to resolve it.... Nexus 4 supports the following preview sizes: - W:1280 H:720 Ratio: 1.777777 W:800 H:480 Ratio: 1.6666666 W:768 H:432 Ratio: 1.7777778 W:720 H:480 Ratio: 1.5 W:640 H:480 Ratio: 1.3333334 W:576 H:432 Ratio: 1.3333334 W:480 H:320 Ratio: 1.5 W:384 H:288 Ratio: 1.3333334 W:352 H:288 Ratio: 1.2222222 W:320 H:240 Ratio: 1.3333334 W:240 H:160 Ratio: 1.5 W:176 H:144 Ratio: 1.2222222 myCamera.setPreviewSize() sets them, and when I call myCamera.getPreviewSize() I get the correct one that I set,

99.9% of all answers on a question in title are as follows: When you searching through the List<Camera.Size> , provided by Camera.Parameters#getSupportedPictureSizes() try to find the size of the same aspect ratio as the camera's preview size which you set via Camera.Parameters.html#setPreviewSize(int,int) , or as close as possible. That's fine, but what if I can't find the picture size of the same aspect ratio as in preview size (Android gives you no guarantee that for every preview size supported by the camera there is a picture size of the same aspect ratio), and all other picture sizes

I have a large number of images that can be any dimension that I need make into the same aspect ratio (basically square). So if one image is 100x300 the output should be 300x300. What I don't want is the image scaled or stretched in any way. I just want a background color (white) applied to the sides of the image, then the original image centered (either vertically or horizontally depending on the original aspect ratio). I've played around with a couple different convert commands, but I have not found the magic one yet - they all either distort the image to reach the aspect ratio, or scale the

I'm working on a zoom functionality. This zoom is a fixed box with 100% of the window size and inside an image with the 200% of the width of the fixed box. This zoom needs to work like this: When the cursor is in the center of the window, the image should be in the center. When the cursor is in the top right corner, the image should stay at the top right corner of the window (so reach the image with the corner) When the cursor is in the middle bottom corner, the image should center horizontally and reach the total bottom, so we can see the middle bottom part of the image. And so on. I make an
