I am just trying to make a simple Skia program. A very simple program, but as I run this code, the output image file never writes anything. I am running this code on VS 2015 and included the skia.lib and OpenGL32.lib static libraries.Can someone tell me why this simple example does not work?#include skiaIncludes.hvoid draw(SkCanvas* canvas) {SkPaint paint;paint.setColor(SK_ColorWHITE);canvas->drawPaint(paint);}int main (){try {    FILE * pFile;    char buffer[100];    pFile = fopen(myfile.png, wb);sk_sp<SkSurface> rasterSurface(        SkSurface::MakeRasterN32Premul(300, 300));    SkCanvas* rasterCanvas = rasterSurface->getCanvas();    //rasterCanvas->save();    rasterCanvas->translate(SkIntToScalar(128), SkIntToScalar(128));    rasterCanvas->rotate(SkIntToScalar(45));    SkRect rect = SkRect::MakeXYWH(-90.5f, -90.5f, 181.0f, 181.0f);    SkPaint paint;    paint.setColor(SK_ColorBLUE);    rasterCanvas->drawRect(rect, paint);    //rasterCanvas->restore();    sk_sp<SkImage> img = rasterSurface->makeImageSnapshot();    sk_sp<SkData> png(img->encode(SkEncodedImageFormat::kPNG, 100));    rasterCanvas->drawImage(img, 0, 0);    png->MakeFromFILE(pFile);    //sk_sp<SkImage> bmap = SkImage::MakeFromBitmap(bitmap);    //SkData * encBmap = bmap->encode(SkEncodedImageFormat::kJPEG, 100);    //encBmap->MakeFromFILE(pFile);    fclose(pFile);}catch (std::exception ex){    printf(ex.what());}return 0;}Header file :#pragma once#include core/SkData.h#include core/SkImage.h#include core/SkStream.h#include core/SkSurface.h#include core/SkCanvas.h#include core/SkGraphics.h#include core/SkImageEncoder.h#include gpu/gl/GrGLInterface.h#include gpu/gl/GrGLExtensions.h#include <fstream>#include <sys/stat.h>#include <sys/types.h>#include <fcntl.h>#include <exception>#include <iostream>//#include gpu/gl/GrGLUtil.h
