If you don’t have the exact size, there are two things that can happen: Upscaling @3x or @2x can be upscaled from @1x but usually the visual result is blurry, with thick lines and doesn’t look good. Upscaling @3x from @2x can be even worse because subpixels must be used. Downscaling In general, the results … Read more
Use ffprobe (part of FFmpeg toolkit) example: ffprobe -v quiet -print_format json -show_format -show_streams ~/Movies/big_buck_bunny_720p_5mb.mp4 output: { “streams”: [ { “index”: 0, “codec_name”: “h264”, “codec_long_name”: “H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10”, “profile”: “Main”, “codec_type”: “video”, “codec_time_base”: “1/50”, “codec_tag_string”: “avc1”, “codec_tag”: “0x31637661”, “width”: 1280, “height”: 720, “coded_width”: 1280, “coded_height”: 720, “has_b_frames”: 0, … Read more
[Edit: Check your browser’s devtools first! As @SkylarIttner points out in the comments, tools for responsive design testing have been rolled out since in most browsers since the below solution was posted. They are likely the best/easiest option now.] You could, correct me if I’m wrong, simply create an iframe with style=”desired width & height” … Read more
The advice these days is: Optimize for 1024×768. For most sites this will cover most visitors. Most logs show that 92-99% of your visits will be over 1024 wide. While 1280 is increasingly common, there are still lots at 1024 and some below that. Optimize for this but don’t ignore the others. 1024 = ~960. … Read more
UPDATE: New link for the icons image size by apple. https://developer.apple.com/ios/human-interface-guidelines/graphics/image-size-and-resolution/ Yes it’s True here it is Apple provide Official documentation regarding icon’s or image size you have to set images for iPhone6 and iPhone6+ For iPhone 6: 750 x 1334 (@2x) for portrait 1334 x 750 (@2x) for landscape For iPhone 6 Plus: 1242 … Read more
All the answers here show a dp->px conversion rather than px->dp, which is what the OP asked for. Note that TypedValue.applyDimension cannot be used to convert px->dp, for that you must use the method described here: https://stackoverflow.com/a/17880012/504611 (quoted below for convenience). fun Context.dpToPx(dp: Int): Int { return (dp * resources.displayMetrics.density).toInt() } fun Context.pxToDp(px: Int): Int … Read more
You can get the screen size with the Toolkit.getScreenSize() method. Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize(); double width = screenSize.getWidth(); double height = screenSize.getHeight(); On a multi-monitor configuration you should use this : GraphicsDevice gd = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice(); int width = gd.getDisplayMode().getWidth(); int height = gd.getDisplayMode().getHeight(); If you want to get the screen resolution in DPI you’ll have … Read more
I created a PyPI module for this reason: pip install screeninfo The code: from screeninfo import get_monitors for m in get_monitors(): print(str(m)) Result: Monitor(x=3840, y=0, width=3840, height=2160, width_mm=1420, height_mm=800, name=”HDMI-0″, is_primary=False) Monitor(x=0, y=0, width=3840, height=2160, width_mm=708, height_mm=399, name=”DP-0″, is_primary=True) It supports multi monitor environments. Its goal is to be cross platform; for now it supports … Read more
Java code: // Converts 14 dip into its equivalent px float dip = 14f; Resources r = getResources(); float px = TypedValue.applyDimension( TypedValue.COMPLEX_UNIT_DIP, dip, r.getDisplayMetrics() ); Kotlin code: val dip = 14f val r: Resources = resources val px = TypedValue.applyDimension( TypedValue.COMPLEX_UNIT_DIP, dip, r.displayMetrics ) Kotlin extension: val Number.toPx get() = TypedValue.applyDimension( TypedValue.COMPLEX_UNIT_DIP, this.toFloat(), Resources.getSystem().displayMetrics)
