Frequently Asked Questions

Is the conversion process lossy?

Yes, converting from the vector-based CALS format to the raster-based SUN format is inherently lossy. Some detail may be lost during the rasterization process. The quality of the resulting SUN image depends on the resolution settings used during conversion.

What is the maximum file size I can upload?

The maximum file size for uploads is 50MB. If your CALS file exceeds this limit, please consider splitting it into smaller parts or using a desktop conversion tool.

How long does the conversion take?

The conversion time depends on the size and complexity of the CALS file. Smaller files typically convert within seconds, while larger files may take a few minutes.

About CALS and SUN Formats

CALS (Computer-Aided Layout System) is a document format originally developed for technical documentation, particularly in the aerospace and defense industries. It's known for its ability to handle complex layouts and graphics. SUN, on the other hand, is a raster graphics format commonly used for storing images. Converting from CALS to SUN allows you to transform vector-based CALS documents into a more universally viewable image format. This is useful for archiving, sharing, or displaying CALS content on platforms that don't natively support the CALS format. The conversion process essentially rasterizes the CALS document, creating a pixel-based image representation.
