Videodev->surface = videoClient->createSurface (pid, 0, width, height, PIXEL_FORMAT_RGB_565, 0x00000200 | 0x00000000) //SurfaceComposer::ePushBuffers || ISurfaceComposer::eFXSurfaceNormal 1 Im trying to draw a rounded rectangle with transparency with the library Skia.

Skia is an open source 2D graphics library which works on multiple hardware and software platforms. Some strange blue dots appeared, not my expected red rectangle. In this article we show how to create simple 2D graphics in C using SkiaSharp library. These are subclasses of different aspects of the drawing pipeline, that when referenced by a paint, are called to override some part of the drawing pipeline. Videodev->isurface->postBuffer(videodev->frame_offset) Beyond simple attributes such as color, strokes, and text values, paints support effects.
