"content": "# ShadowLayout a css like shadow for android\n\nHave you ever wanted a CSS type of shadow in your Android project ? No?! Me neither but designers\nkeep using it and the death flag is triggered when the app isn't a copy of the design. So, there it goes.\n\nIt do much more than casting a shadow so the name can be inaccurate. Internally, it uses the native \n`ScriptIntrinsicBlur` render script so it can easily blur the whole layout like the\n[Blurry](https://github.com/wasabeef/Blurry) library.\n\n# Requirements\n\nAndroid 5.+ (API 21)\n\n# Gradle\n\nThe project is hosted on maven Central :\n```groovy\nallprojects {\n repositories {\n mavenCentral()\n }\n}\n```\n\nThen add dependency :\n```groovy\ndependencies {\n implementation(\"net.orandja.shadowlayout:shadowlayout:1.0.1\")\n}\n```\n\n\n# Usage\n\nAdd `android:clipChildren=\"false\"`, `android:clipToPadding=\"false\"` to the parent layout to let ShadowLayout draw outside of view bounds.\n\n```xml\n\n\n \n\n\n```\n\n\n\n## Parameters\n\nDefault value in parenthesis\n\n- `shadow_radius` (6f) The radius of the gaussian blur in float. See #Rules of downscaling section to see how it works. \n- `shadow_x_shift` (0dp) Shift on the horizontal axis in dp\n- `shadow_y_shift` (0dp) Shift on the vertical axis in dp\n- `shadow_color` (#33000000) Color of the casted shadow\n- `shadow_downscale` (1f) Downscale of the internal bitmap that render the shadow. The higher the downscale, the lower in size is the bitmap. At 2, the size of bitmap is halved. \n- `shadow_with_foreground` (true) Draw the actual view on top of the shadow.\n- `shadow_with_color` (false) Keep all the subview colors in the blur. Coupled with `shadow_with_foreground` at false, a blur image can be render on screen.\n- `shadow_with_dpi_scale` (true) Downscale the internal bitmap by the current smartphone dpi. A 100dp view will result in a 100px bitmap. \n- `shadow_with_css_scale` (true) Downscale by 5/3 more. Because CSS shadow standard blur by a half more than the real blur size.\n- `shadow_cast_only_background` (false) Only render the background and not the view as shadow\n\n\n## Limitations\n\nThe default implementation of android gaussian blur (`ScriptIntrinsicBlur` render script) is limited to 25 pixels at max. \nTo counter that, the layout downscale the real render of the view inside a bitmap (ALPHA_8 or RGBA with `shadow_with_color` at true). \nThen blur it. Then renders the blur inside the canvas. Then **redraw** the view in the canvas. (`shadow_with_foreground` at true)\n\nThe radius can mean multiple things depending on the configurations. \n\n## Rules of downscaling\n\nWhen no downscale are applied:\n \n```xml\n\n```\n\nThe internal bitmap is the same size of the view. The radius is the number of **pixels** blured around.\nWith high dpi, it will be hard to see the effect. However, in some cases, it can be usefull to have a nice looking blur at the expense of more memory.\nThe max radius is 25 pixels. The parameter `shadow_downscale` multiply the max radius by its value. So at shadow_downscale=\"2.5\" it increases the max radius to 62.5f.\n\nWhen `app:shadow_with_dpi_scale=\"true\"`: Downscale the internal bitmap by the current smartphone dpi. A 100dp view will result in a 100px bitmap.\nThe radius means **dp**. It blurs up to 25dp.\n\nWhen `app:shadow_with_css_scale=\"true\"`: Same as dpi, it will add a 5/3 downscale to mimic the CSS shadow blur.\n\n# Shadow anything\n\nAs said before since it draw the whole layout it can cast a shadow of anything. Like text:\n\n```xml\n \n\n \n\n \n```\n\n\n\nSince `shadow_with_color` is at true, the drawn shadow is of the same color of the text rendered.\nThe color parameter only affect alpha. \n"
