如何在 .NET 中使用 ChatGPT 创建 AI 增强的 PDF 工作流

using Aspose.Pdf.Plugins;

// 1. Extract text from the PDF
global::System.String inputPath = @"C:\Docs\input.pdf";
var extractor = new TextExtractor();
var textOptions = new TextExtractorOptions();
textOptions.AddInput(new FileDataSource(inputPath));
var extractionResult = extractor.Process(textOptions);
string extractedText = extractionResult.ResultCollection[0].ToString();

// 2. Send to ChatGPT (pseudo-code, insert your actual OpenAI client logic)
string aiPrompt = $"Summarize the key points and list all next steps from this PDF:\n{extractedText}";
string aiResponse = /* ChatGPT API call */;

// 3. Add AI response as annotation in PDF
var editor = new FormEditor();
var addOptions = new FormEditorAddOptions(/* set up annotation or text field with aiResponse */);
addOptions.AddInput(new FileDataSource(inputPath));
addOptions.AddOutput(new FileDataSource(@"C:\Docs\output-annotated.pdf"));
editor.Process(addOptions);
