The latest version is marketed as CorelDraw Graphics Suite 2019 (equivalent to version 21), and was released in 12 March, 2019. CorelDraw is meant to edit two-dimensional pictures like logos and posters.

·        History

In 1987, Corel engineers Michel broth and Pat Berne undertook to develop a vector-based illustration program to bundle with their publication systems. That program, CorelDraw, was initially released in 1989. CorelDraw Onex and 2.x ran beneath Windows two’s and 3.0. CorelDraw three.0 came into its own with Microsoft's unleash of Windows three.1. The inclusion of TrueType in Windows three.1 remodeled CorelDraw into a heavy illustration program capable of mistreatment system-installed define fonts while not requiring third-party code like Adobe sort Manager; paired with a photo-editing program (Corel Photo-Paint), a font manager and several other other items of computer code, it was also part of the first all-in-one graphics suite.

·        Supported platforms

1. CorelDraw was originally developed for Microsoft Windows 3 and currently runs on Windows XP, Windows Vista, Windows 7, Windows 8 and Windows 10. The latest version, 2019, was released on March 12, 2019.
2. CorelDraw Graphics Suite 2019 for Macintosh OS X was free on March twelve, 2019, when Associate in Nursing 18-year absence (the last version for OS X was version eleven, released in 2001).
3. With version six, CorelDraw introduced the automation of tasks using a Corel proprietary scripting language, COREL Script. With version ten, support for VBA (Visual Basic for Applications) was introduced for scripting by what Corel calls currently macros. Corel recommends to now not use the COREL Script language however solely VBA.

·        CDR file format

·        Structure

1. In its first versions, the CDR file format was a totally proprietary file format primarily used for vector graphic drawings, recognizable by the primary 2 bytes of the file being "WL". Starting with CorelDraw three, the file format modified to a Resource Interchange File Format (RIFF) envelope, recognizable by the first four bytes of the file being "RIFF", and a "CDR*verse" in bytes nine to fifteen, with the asterisk "*" being just a blank in early versions. Beginning with CorelDraw 4 it included the version number of the writing program in hex ("4" which means version four, "D" which means version 14). The actual data chunk of the RIFF remains a Corel proprietary format.
2. From version X4 (14) on, the CDR file is a ZIP-compressed directory of several files, among them XML files and the RIFF-structured riffdata.cdr with the familiar version signature in versions X4 (CDREvrsn) and X5 (Carvers), and a root.dat with CorelDraw X6, where the bytes 9 to 15 look slightly different -- "Caregiver" in a file created with X6. "F" was the last valid hex digit, and also the "fever" currently indicates that the letter before now not represents a hex digit.
3. There is no in public on the market CDR file format specification.
4. Other CorelDraw file formats embrace CorelDraw Compressed (CDX), CorelDraw Template (CDT) and Corel Presentation Exchange (CMX).

·        Use of CDR files in other programs

1. In December 2006 the sK1 ASCII text file project team began to reverse-engineer the CDR format. The results and also the initial operating shot of the CDR bourgeois were bestowed at the Libre Graphics Meeting 2007 conference going down in mite 2007 in city (Canada). Later on, the team parsed the structure of other Corel formats with the help of the open source CDR adventurer. As of 2008, the sK1 project claims to have the best import support for CorelDraw file formats among open source software programs. The sK1 project developed conjointly the Unconverted, a command line open source tool which supports conversion from CorelDraw ver.7-X4 formats (CDR/CDT/CCX/CDRX/CMX) to other formats. Unconverted is also used in the Inkscape and Scribes open source projects as an external tool for importing CorelDraw files.
2. In 2007, Microsoft blocked CDR file format in Microsoft work 2003 with the discharge of Service Pack 3 for work 2003.Microsoft later apologized for inaccurately blaming the CDR file format and different formats for security issues in Microsoft workplace and discharged some tools for resolution this downside.
3. In 2012 the joint LibreOffice/re-lab team enforced libido, a library for reading CDR files from version seven to X3 and CMX files. The library has in depth support for shapes and their properties, together with support for color management and spot colors, and features a basic support for text. The library provides a constitutional convertor to SVG, and a convertor to OpenDocument is provided by writer perfect package. The libido library is used in LibreOffice starting from version 3.6, and thanks to public API it can be freely used by other applications.
