Answer : img { display: block; max-width:230px; max-height:95px; width: auto; height: auto; } <p>This image is originally 400x400 pixels, but should get resized by the CSS:</p> <img width="400" height="400" src="http://i.stack.imgur.com/aEEkn.png"> This will make image shrink if it's too big for specified area (as downside, it will not enlarge image). I've struggled with this problem quite hard, and eventually arrived at this simple solution: object-fit: cover; width: 100%; height: 250px; You can adjust the width and height to fit your needs, and the object-fit property will do the cropping for you. More information about the possible values for the object-fit property and a compatibility table are available here: https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit Cheers. The solutions below will allow scaling up and scaling down of the image , depending on the parent box width. All images have a parent cont...

Answer : If you press C it will toggle through the crop ratios and may help you with eliminating the black bars. Well, I should have checked VLC's Video menu as I did while posting this question...

Simply go to VLC Player preferences > Video (you must be in "All" mode, not "Simple" mode). On the right-hand side, scroll down to "Video cropping" and type in either "16:10", "16:9", or "4:3", depending on what your screen's aspect ratio is. Press the Save button at the bottom. If black lines remain, then they are actually part of the video as opposed to just an empty section of the screen. In this case, adjusting manually is the only logical option left.

Answer : I'm using this method -> based on API Demos to get my Preview Size: private Camera.Size getOptimalPreviewSize(List<Camera.Size> sizes, int w, int h) { final double ASPECT_TOLERANCE = 0.1; double targetRatio=(double)h / w; if (sizes == null) return null; Camera.Size optimalSize = null; double minDiff = Double.MAX_VALUE; int targetHeight = h; for (Camera.Size size : sizes) { double ratio = (double) size.width / size.height; if (Math.abs(ratio - targetRatio) > ASPECT_TOLERANCE) continue; if (Math.abs(size.height - targetHeight) < minDiff) { optimalSize = size; minDiff = Math.abs(size.height - targetHeight); } } if (optimalSize == null) { minDiff = Double.MAX_VALUE; for (Camera.Size size : sizes) { if (Math.abs(size.height - targetHeight) < minDiff) { ...
