After a SkiaSharp application has created or modified a bitmap, the application might want to save the bitmap to the user's photo library:This task encompasses two steps:Converting the SkiaSharp bitmap to data in a particular file format, such as JPEG or PNG. Saving the res...
SKBitmap bitmap = new SKBitmap((int) _canvasView.Width, (int) _canvasView.Height); SKCanvas canvas = new SKCanvas(bitmap); //Draw on canvas from stored commands DrawPath, etc. //Get the file to store to. Then save the bitmap to file. using (Stream s = await file.OpenAsync(...
中 // 通常情况下,你会直接保存SKBitmap,如方法一所示 } 注意:在方法二中,从SKBitmap到SKImage的转换主要是为了展示如何处理SKImage对象,但在将SKBitmap保存为PNG的上下文中,这一步是多余的。通常,你会直接使用SKBitmap的Encode和SaveTo方法来保存文件,如方法一所示。 综上所述,对于大多数将SKBitmap保存为...
We save the bitmap to a file. SkiaSharp lines Lines are drawn withDrawLine. Program.cs using SkiaSharp; using SKBitmap bmp = new(640, 480); using SKCanvas canvas = new(bmp); canvas.Clear(SKColor.Parse("#003366")); using SKPaint p1 = new() { Color = SKColors.FloralWhite, StrokeWidt...

在上面的代码中,我们首先加载一张图片和一个水印图片。然后,我们定义了水印的位置和大小。接下来,我们创建一个绘图表面,并使用DrawBitmap函数在表面上绘制原始图片和水印。最后,使用Save函数将带有水印的图片保存为PNG格式。 图片缩放 图片缩放是一项常见的操作,它允许我们调整图片的大小。SkiaSharp库提供了用于缩放的函...
