Save Images with Different Processing in IronOCR

Updated: July 6, 2026

How can I save an image with different image processing/image filters applied?

Apply the following simple code example:

// Create a new instance of OcrInput and load the image from a text box input for file path.
OcrInput input = new OcrInput();
input.LoadImage(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.GetPages())
{
    // 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 and load the image from a text box input for file path.
OcrInput input = new OcrInput();
input.LoadImage(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.GetPages())
{
    // Save each processed page as an image with a unique timestamped filename.
    p.SaveAsImage($"{outputPath}\\{DateTime.Now.ToString("yyyyMMddHHmmss")}.png");
}
