## Specifications used
1616
This library was created using the specifications lay out in ["PDF 32000-1:2008, Document management – Portable document format – Part 1: PDF 1.7"](https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/PDF32000_2008.pdf).

The full specifications are not implemented. This library currently only supports placements of images and setting the different boxes.

The full specifications are not implemented. This library currently only supports placements of images, drawing of vector shapes (CMYK, RGB & gray scale), and setting the different boxes.

## Remarks
2121
Unlike most PDF libraries this library does not create the entire PDF model in memory before writing the PDF to a (file)stream. Most libaries support editing capabilities, because this libary only supports creating files, it was not necessary to keep the PDF model in memory. This results in less memory usage.
