Template sources

Aspose.OMR for C++ 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.
BMP	Bitmap image file. Supported by almost any device, but the file size can be very large.

Printable forms

Once the template source code is ready, you can generate a printable form from it. Aspose.OMR for C++ creates 2 files for each form:
