Template sources
Aspose.OMR for Java supports a specialized markup language for designing OMR forms. Form layout is provided in a lightweight text markup language specifically tailored for describing machine-readable forms. It is content-focused, with minimal number of tags or formatting instructions.
The forms can be customized by adding images, such as logos or photos. The images are provided in the following formats:
| Format | Details |
|---|---|
| JPEG | A widely used format for digital images. Small file size, but image quality may be slightly reduced due to lossy compression. |
| PNG | An open, extensible image format with lossless compression. |
Printable forms
Once the template source code is ready, you can generate a printable form from it. Aspose.OMR for Java creates 2 files for each form:
| File | Details |
|---|---|
| {form name}.PNG | Printable form image in Portable Network Graphics (.PNG) format. |
| {form name}.OMR | A recognition pattern used by Aspose.OMR recognition engine, in a special .OMR format (JSON-based). |
