如何保存应用了不同图像处理/图像滤镜的图像？
应用以下简单代码示例：
// Create a new instance of OcrInput from a text box input for file path.
OcrInput input = new OcrInput(browsFile_txt.Text);
// Apply a grayscale filter to the image.
input.ToGrayScale();
// Iterate through each page in the OcrInput object.
foreach (var p in input.Pages)
{
// Save each processed page as an image with a unique timestamped filename.
p.SaveAsImage($"{outputPath}\\{DateTime.Now.ToString("yyyyMMddHHmmss")}.png");
}' Create a new instance of OcrInput from a text box input for file path.
Dim input As New OcrInput(browsFile_txt.Text)
' Apply a grayscale filter to the image.
input.ToGrayScale()
' Iterate through each page in the OcrInput object.
For Each p In input.Pages
' Save each processed page as an image with a unique timestamped filename.
p.SaveAsImage($"{outputPath}\{DateTime.Now.ToString("yyyyMMddHHmmss")}.png")
Next p' Create a new instance of OcrInput from a text box input for file path.
Dim input As New OcrInput(browsFile_txt.Text)
' Apply a grayscale filter to the image.
input.ToGrayScale()
' Iterate through each page in the OcrInput object.
For Each p In input.Pages
' Save each processed page as an image with a unique timestamped filename.
p.SaveAsImage($"{outputPath}\{DateTime.Now.ToString("yyyyMMddHHmmss")}.png")
