My Issue is I don't know how to convert the canvas to byte array. I am using below code複製 SKBitmap bitmap = new SKBitmap((int)canvasView.Width, (int)canvasView.Height); SKCanvas canvas = new SKCanvas(bitmap); // create an image COPY //SKImage image = SKImage.FromBitmap(bit...
}//canvas.Save();using(varavatarImage = SKImage.FromBitmap(SKBitmap.Decode("C:\\Users\\Administrator\\source\\repos\\FurionProject\\FurionProject.Web.Entry\\img\\gz.png"))) {//35,50是你图片的坐标 注意:不要超出画布的大小,否则无法显示 300 300是图片的大小varrect = SKRect.Create(35,50,...
您可以使用静态SKImage.FromBitmap方法从SKBitmap对象轻松创建SKImage对象,您可以使用PeekPixels方法从SKBitmap对象获取SKPixmap对象。 SKImage定义的没有参数的Encode方法,并自动保存为PNG格式,该无参数方法非常易于使用。 保存 将SKBitmap对象编码为特定的文件格式时,通常会留下某种流对象或数据数组。一些Encode方法(包括...
public static byte[] Screenshot(string fromImagePath, int offsetX, int offsetY, int width, int height) { using var original = SKBitmap.Decode(fromImagePath); using SKBitmap bitmap = new(width, height); using SKCanvas canvas = new(bitmap); SKRect sourceRect = new(offsetX, offsetY, ...
Returns the byte size of the pixels, based on the Height and RowBytes. Bytes Gets a copy of all the pixel data as a byte array. BytesPerPixel Gets the number of bytes used per pixel. ColorSpace Gets the color space of the bitmap. ColorTable Obsolete. Gets the color table of the...
此外,SKImage和SKPixmap類別也會定義Encode稍微多用途的方法,以及您可能偏好的方法。 您可以使用靜態SKImage.FromBitmap方法,輕鬆地從SKBitmap物件建立SKImage物件。 您可以使用 方法,從SKBitmap物件取得SKPixmap物件PeekPixels。 所SKImage定義的其中Encode一個方法沒有參數,而且會自動儲存為 PNG 格式。 這個無參數方法很...
