OMR 表单的结构和布局在一个使用特殊符号的纯文本文件中定义。您可以使用任何文本编辑器（包括记事本）创建它。只需 4 行代码即可生成 150 个问题的机器可读答题纸：
如何设计答题纸
?answer_sheet=answers elements_count=150 answers_count=5 columns_count=3
完成表单结构和布局后，您只需要 3 行代码即可构建一个简单的实用程序，从中生成可打印的页面：
如何生成可打印的表格
// Initialize Aspose.OMR engine OmrEngine engine = new OmrEngine(); // Generate machine-readable form from the markup GenerationResult res = engine.generateTemplate("template.txt"); // Save printable OMR form as an image res.Save("print", "answer-sheet");光学标记读取器
使用 Aspose.OMR for Java，您只需 5 行代码即可创建功能齐全的可编程光学标记读取器。您可以使用现有的办公室复印机，甚至智能手机摄像头来代替昂贵的 OMR 扫描仪。受访者可以使用钢笔、铅笔或记号笔填写表格，并使用任何类型的标记。
如何识别已完成的表格
// Initialize Aspose.OMR engine OmrEngine engine = new OmrEngine(); // Apply the recognition template TemplateProcessor processor = engine.getTemplateProcessor("pattern.omr"); // Load the scanned or photographed form RecognitionResult result = processor.recognizeImage("completed-form.png"); // Output the recognition result String resultCsv = result.getCsv(); System.out.println(resultCsv);
