打印画布以形成 silverlight 图像

我已使用 WritebleBitmap 类成功地将画布添加到位图，然后尝试使用位图通过 SaveFileDilogue 将图像保存在客户端系统上。我正在使用 FluxJpegCore 图像编码方法，其中我们使用栅格数组按像素生成图像。下面是完成这项工作的代码部分。

        byte[][,] raster = new byte[bands][,];

        for (int i = 0; i < bands; i++)
        {
            raster[i] = new byte[width, height];
        }

        for (int row = 0; row < height; row++)
        {
            for (int column = 0; column < width; column++)
            {
                int pixel = bitmap.Pixels[width * row + column];
                raster[0][column, row] = (byte)(pixel >> 16);
                raster[1][column, row] = (byte)(pixel >> 8);
                raster[2][column, row] = (byte)pixel;
            }
        }

图像保存一切顺利，但是当我缩放图像然后打印它时，代码在“raster[i] = new byte[width, height];”行失败。出现系统内存不足错误。谁能帮我找到这个问题的解决方案？

I have scuccesfully added canvas to bitmap using WritebleBitmap class and then trying to use the bitmap to save image on client system through SaveFileDilogue. I am using the method of FluxJpegCore image encoding where we use raster arrays to generate image pixel-wise.
Below is the part of the code which does the job.

        byte[][,] raster = new byte[bands][,];

        for (int i = 0; i < bands; i++)
        {
            raster[i] = new byte[width, height];
        }

        for (int row = 0; row < height; row++)
        {
            for (int column = 0; column < width; column++)
            {
                int pixel = bitmap.Pixels[width * row + column];
                raster[0][column, row] = (byte)(pixel >> 16);
                raster[1][column, row] = (byte)(pixel >> 8);
                raster[2][column, row] = (byte)pixel;
            }
        }

All goes fine with image saving, however when i zoom the image and then print it, the code fails at the line "raster[i] = new byte[width, height];". System out of memory error is raised. Can anyone help me to find the solution on this?
