如何将图像融入 .NET 中的网络或摩萨格式

int columns = 4, rows = 3; // Change as needed
string[] files = Directory.GetFiles("./input", "*.jpg");

var images = files.Take(columns * rows).Select(f => Image.Load(f)).ToList();
int thumbWidth = 200, thumbHeight = 200;
foreach (var img in images) img.Resize(thumbWidth, thumbHeight, ResizeType.LanczosResample);

int totalWidth = columns * thumbWidth;
int totalHeight = rows * thumbHeight;
using (var outImg = Image.Create(new PngOptions(), totalWidth, totalHeight))
{
    var graphics = new Aspose.Imaging.Graphics(outImg);
    for (int row = 0; row < rows; row++)
    {
        for (int col = 0; col < columns; col++)
        {
            int idx = row * columns + col;
            if (idx >= images.Count) break;
            graphics.DrawImage(images[idx], new Aspose.Imaging.Rectangle(col * thumbWidth, row * thumbHeight, thumbWidth, thumbHeight));
        }
    }
    outImg.Save("./output/mosaic.png");
}
images.ForEach(img => img.Dispose());
