在 IronOCR 中保存具有不同处理效果的图像

Updated: 2026年6月29日

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.
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")
Next p
