SaveArgb32Pixels

RasterImage.SaveArgb32Pixels method

保存 32 位 ARGB 像素。

public void SaveArgb32Pixels(Rectangle rectangle, int[] pixels)
范围类型描述
rectangleRectangle保存像素的矩形。
pixelsInt32[]32 位 ARGB 像素阵列。

例子

以下示例使用 Aspose.Imaging.RasterImage.SaveArgb32Pixels 方法用黑色像素填充光栅图像的中心区域。

[C#]

string dir = "c:\\temp\\";

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    Aspose.Imaging.RasterImage rasterImage = (Aspose.Imaging.RasterImage)image;

    // 黑色方块
    int[] pixels = new int[(rasterImage.Width / 2) * (rasterImage.Height / 2)];
    for (int i = 0; i < pixels.Length; i++)
    {
        pixels[i] = Color.Black.ToArgb();
    }

    // 在图像中心绘制黑色方块。
    Aspose.Imaging.Rectangle area = new Aspose.Imaging.Rectangle(rasterImage.Width / 4, rasterImage.Height / 4, rasterImage.Width / 2, rasterImage.Height / 2);
    rasterImage.SaveArgb32Pixels(area, pixels);

    rasterImage.Save(dir + "sample.SaveArgb32Pixels.png");
}
