In 2012 the joint LibreOffice/re-lab team implemented libcdr, a library for reading CDR files from version 7 to X3 and CMX files. The library has extensive support for shapes and their properties, including support for color management and spot colors, and has a basic support for text. The library provides a built-in converter to SVG, and a converter to OpenDocument is provided by writerperfect package. The libcdr library is used in LibreOffice starting from version 3.6, and thanks to public API it can be freely used by other applications.
On the "Prepress" tab you have the option of activating "Bleed Limit". Even if the current document does not have an active bleed, you can activate it while creating the PDF. But remember that the objects must extend out from the page limit. Activating the "Bleed Limit" does not automatically increase the size of objects used to create the design. Another option which is often useful is to activate "Crop marks" to indicate the limits of our design. For this reason it is important that the page size is the real size.
