| String dataDir = Utils.getSharedDataDir(ConvertWorksheettoImageFile.class) + "TechnicalArticles/"; | |
| // Create a new Workbook object | |
| // Open a template excel file | |
| Workbook book = new Workbook(dataDir + "book1.xlsx"); | |
| // Get the first worksheet | |
| Worksheet sheet = book.getWorksheets().get(0); | |
| // Define ImageOrPrintOptions | |
| ImageOrPrintOptions imgOptions = new ImageOrPrintOptions(); | |
| // Specify the image format | |
| imgOptions.setImageType(ImageType.JPEG); | |
| // Render the sheet with respect to specified image/print options | |
| SheetRender render = new SheetRender(sheet, imgOptions); | |
| // Render the image for the sheet | |

Using Aspose.Cells to Convert Worksheet to Image File by Page
This example shows how to use Aspose.Cells to convert a worksheet from a template workbook that has several pages to one image file per page.
| // For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
| // The path to the documents directory. | |
| String dataDir = Utils.getSharedDataDir(ConvertWorksheetToImageByPage.class) + "TechnicalArticles/"; | |
| // Create a new Workbook object | |
| // Open a template excel file | |
| Workbook book = new Workbook(dataDir + "ConvertWorksheetToImageByPage.xlsx"); | |
| // Get the first worksheet | |
| Worksheet sheet = book.getWorksheets().get(0); | |
| // Define ImageOrPrintOptions | |
| ImageOrPrintOptions options = new ImageOrPrintOptions(); | |
| // Set Resolution | |
| options.setHorizontalResolution(200); | |
| options.setVerticalResolution(200); | |
| options.setImageType(ImageType.TIFF); | |
| // Sheet2Image by page conversion | |
| SheetRender render = new SheetRender(sheet, options); | |
| for (int j = 0; j < render.getPageCount(); j++) { | |
| render.toImage(j, dataDir + sheet.getName() + " Page" + (j + 1) + ".tif"); | |
| } |
Result
After executing the above code, the worksheet named Sheet1 is converted into two image files (1 per page) Sheet 1 Page 1.Tiff and Sheet 1 Page 2.Tiff.
Generated image file (Sheet 1 Page 1.Tiff)
Generated image file (Sheet 1 Page 2.Tiff)
