.NET을 사용하여 이미지와 경계 또는 라벨을 추가하는 방법

bool mergeHorizontal = true; // or false for vertical
string[] files = Directory.GetFiles("./input", "*.jpg");

var images = files.Select(f => Image.Load(f)).ToList();
int borderThickness = 5;
Color borderColor = Color.Black;
Font labelFont = new Font("Arial", 24, FontStyle.Bold);
Color labelColor = Color.Blue;
string[] labels = files.Select(Path.GetFileNameWithoutExtension).ToArray();

int labelHeight = 40;
int totalWidth = mergeHorizontal ? images.Sum(i => i.Width + borderThickness * 2) : images.Max(i => i.Width) + borderThickness * 2;
int totalHeight = mergeHorizontal ? images.Max(i => i.Height) + borderThickness * 2 + labelHeight : images.Sum(i => i.Height + borderThickness * 2 + labelHeight);

using (var outImg = Image.Create(new PngOptions(), totalWidth, totalHeight))
{
    var graphics = new Aspose.Imaging.Graphics(outImg);
    graphics.Clear(Color.White);
    int x = 0, y = 0;
    for (int i = 0; i < images.Count; i++)
    {
        var img = images[i];
        int drawX = mergeHorizontal ? x : (totalWidth - img.Width) / 2;
        int drawY = mergeHorizontal ? (totalHeight - img.Height - labelHeight) / 2 : y;
        // Draw border
        graphics.DrawRectangle(new Pen(borderColor, borderThickness), drawX - borderThickness, drawY - borderThickness, img.Width + borderThickness * 2, img.Height + borderThickness * 2);
        // Draw image
        graphics.DrawImage(img, drawX, drawY, img.Width, img.Height);
        // Draw label
        graphics.DrawString(labels[i], labelFont, new SolidBrush(labelColor), drawX, drawY + img.Height + 5);
        if (mergeHorizontal)
            x += img.Width + borderThickness * 2;
        else
            y += img.Height + borderThickness * 2 + labelHeight;
    }
    outImg.Save("./output/merged_with_borders_labels.png");
}
images.ForEach(img => img.Dispose());
