Get or Set CGM File Information via C++
Aspose.PDF for C++ also allows you to get information about your CGM document and lets you take informed decisions before your conversion process. In order to get file specific information of a CGM file, you first need to call the get_Info() method of Document class. Once the DocumentInfo object is retrieved, you can get the values of the individual properties. Furthermore, you can also set the properties by using respective methods of DocumentInfo class.
| // supports PDF, CGM, EPUB, TeX, PCL, PS, SVG, XPS, MD, MHTML, XML, and XSLFO file format | |
| // load the PDF. | |
| auto doc = MakeObject<Document>(L"DocumentInfo.pdf"); | |
| // get document informtion object | |
| info = doc->get_Info(); | |
| // set author | |
| info->set_Author(L"John Doe"); | |
| // set subject | |
| info->set_Subject(L"Working with Document Info"); | |
| // set title | |
| info->set_Title(L"Get/set document's info"); | |
| // get and print document information | |
| Console::WriteLine(L"Author: {0}", info->get_Author()); | |
| Console::WriteLine(L"Subject: {0}", info->get_Subject()); | |
| Console::WriteLine(L"Title: {0}", info->get_Title()); |
Save XLTM File Format to Stream via C++
Aspose.Cells for C++ allows saving XLTM file format to stream. To save files to a stream, create a MemoryStream or FileStream object and save the file to that stream object by calling the IWorkbook object’s Save method. Specify the desired file format using the SaveFormat enumeration when calling the Save method.
| // supports CSV, XLSB, XLSM, XLT, XLTX, XLTM, XLAM, TSV, TXT, ODS, DIF, MD, SXC, and FODS file format | |
| // load sample CSV file | |
| intrusive_ptr<IWorkbook> workbook = Factory::CreateIWorkbook("sampleExcelFile.csv"); | |
| // create FileStream object | |
| intrusive_ptr<FileStream> stream = new FileStream("outputSavingFiletoStream.csv"), FileMode_CreateNew); | |
| // save the Workbook to Stream | |
| workbook->Save(stream, SaveFormat_Csv); | |
| // working with stream.. |
