Template sources
Aspose.OMR for .NET supports a specialized markup language for designing OMR forms. Form layout can be provided in one of the following formats:

Once the template source code is ready, you can generate a printable document from it. Aspose.OMR for .NET intellectually selects the file format based on the provided extension:
| Extension | Details |

| Portable Document Format, the de facto industry standard for printed documents. | |

| .PNG | Portable Network Graphics, an open, extensible image format with lossless compression. |
| .TIFF or .TIF | Tag Image File Format, abbreviated as TIFF or TIF. The most popular high-quality graphics format among artists, photographers and the publishing industry. |
| .GIF | Small-sized image files that are limited to 256 colors. Best suited for websites and slow networks. |
| .BMP | Bitmap image file. Supported by almost any device, but the file size can be very large. |
