我目前正在制作精灵表制作器，但在拼接目录中的所有图像时遇到了麻烦。到目前为止，我的代码可以读取用户输入的目录中所有文件的名称，并将它们放在字符串列表中。但是我不确定如何将它们缝合在一起。
我现在添加了用于拼接图像的代码，并在程序保存拼接图像时出现异常
。我拉入的图像是 *.png，输出也是如此。图像需要水平缝合。
我当前的代码：
static void Main()
{
bool cont = false;
bool skip = false;
while (cont == false)
{
Console.WriteLine("Enter a Folder name(end to end):");
string fold = Console.ReadLine();
if (fold.Equals("end"))
{
break;
}
try
{
string[] files = Directory.GetFiles(@"sprites\" + fold, "*.PNG");
foreach (string file in files)
{
Console.WriteLine(file);
}
skip = false;
}
catch (Exception)
{
Console.WriteLine("Folder not Found!");
Console.WriteLine("Try Again!");
cont = false;
skip = true;
}
if (skip != true)
{
try
{
string[] files = Directory.GetFiles(@"sprites\" + fold, "*.PNG");
System.Drawing.Bitmap stitchedImage = Combine(files);
Console.WriteLine("save filename (no extention)");
string fil = Console.ReadLine();
stitchedImage.Save(@"/sheets/"+fil+".png", System.Drawing.Imaging.ImageFormat.Png);
cont = true;
}
catch (Exception ex)
{
Console.WriteLine("Error Creating Sprite Sheet");
Console.WriteLine(ex);
Console.WriteLine("Please Try Again!");
}
}
}
Console.WriteLine("Done!");
Console.WriteLine("Program will now exit(Enter to continue)");
Console.ReadLine();
}
public static System.Drawing.Bitmap Combine(string[] files)
{
//read all images into memory
List<System.Drawing.Bitmap> images = new List<System.Drawing.Bitmap>();
System.Drawing.Bitmap finalImage = null;
try
{
int width = 0;
int height = 0;
foreach (string image in files)
{
//create a Bitmap from the file and add it to the list
System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(image);
//update the size of the final bitmap
width += bitmap.Width;
height = bitmap.Height > height ? bitmap.Height : height;
images.Add(bitmap);
}
//create a bitmap to hold the combined image
finalImage = new System.Drawing.Bitmap(width, height);
//get a graphics object from the image so we can draw on it
using (System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(finalImage))
{
//set background color
g.Clear(System.Drawing.Color.Black);
//go through each image and draw it on the final image
int offset = 0;
foreach (System.Drawing.Bitmap image in images)
{
g.DrawImage(image,
new System.Drawing.Rectangle(offset, 0, image.Width, image.Height));
offset += image.Width;
}
}
return finalImage;
}
catch (Exception ex)
{
if (finalImage != null)
{
finalImage.Dispose();
}
Console.WriteLine(ex);
throw ex;
}
finally
{
//clean up memory
foreach (System.Drawing.Bitmap image in images)
{
image.Dispose();
}
}
}
