我刚刚在我的膝盖上放了一个Cordova项目,我的任务是建立应用程序并将它们放在商店上.iOS运行良好,但现在我已经用Android打了一堵墙.
所以,每次我构建 - 通过运行cordova build android - 我得到以下错误:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':processDebugResources'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Users/sprince/Library/Android/sdk/build-tools/23.0.2/aapt'' finished with non-zero exit value 1
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED

You may …假设这些是我应用于图像的滤镜.我想知道这些过滤器背后的数学:
filter: contrast(1.3) brightness(0.8) sepia(0.3) saturate(1.5) hue-rotate(-20deg);
我正在寻找特定于CSS的计算或应用于每个像素RGB或整体的任何通用算法.任何帮助都非常感谢.
