OMR 表单的结构和布局在一个纯文本文件中，使用一种特殊的符号来指定。您可以使用任何文本编辑器（包括记事本）创建它。只需 4 行代码即可生成一份包含 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 System::SharedPtr<Api::OmrEngine> engine = System::MakeObject<Api::OmrEngine>(); // Generate machine-readable form from the markup System::SharedPtr<Generation::GenerationResult> result = engine->GenerateTemplate(u"template.txt"); // Save printable OMR form to an image file result.Save("target", "omr-form");光学标记读取器
使用 Aspose.OMR for C++，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 OMR engine System::SharedPtr<Api::OmrEngine> engine = System::MakeObject<Api::OmrEngine>(); // Load recognition pattern file System::SharedPtr<Api::TemplateProcessor> processor = engine->GetTemplateProcessor(u"omr-form.omr"); // Recognize completed survey System::SharedPtr<Model::RecognitionResult> result = processor->RecognizeImage(u"IMG_20220401.jpg"); // Get results in CSV format System::String resultCsv = result->GetCsv();
