SkPaint paint; paint.setColor(SK_ColorRED); paint.setAlpha(128);
SkPaint paint; paint.setColor(SK_ColorWHITE); for (int i = 0; i < 10; i++) { paint.setAlpha(255 - i * 25); canvas.drawRect(rect, paint); }This code draws a series of white rectangles with progressively less opacity, creating a fading effect. SkPaint is part of the Skia Graphics Library, which is included in the package library for many C++ development environments, including Visual Studio, Xcode, and Android Studio.
