CorelDraw (CorelDRAW) is a vector graphics editor developed and marketed by Corel Corporation. It is also the name of the Corel graphics suite, which includes the bitmap-image editor Corel Photo-Paint as well as other graphics-related programs (see below). The latest version is marketed as CorelDraw Graphics Suite 2019 (equivalent to version 21), and was released in 12 March, 2019. CorelDraw is designed to edit two-dimensional images such as logos and posters.
In 1987, Corel engineers Michel Bouillon and Pat Beirne undertook to develop a vector-based illustration program to bundle with their desktop publishing systems. That program, CorelDraw, was initially released in 1989. CorelDraw 1.x and 2.x ran under Windows 2.x and 3.0. CorelDraw 3.0 came into its own with Microsoft's release of Windows 3.1. The inclusion of TrueType in Windows 3.1 transformed CorelDraw into a serious illustration program capable of using system-installed outline fonts without requiring third-party software such as Adobe Type Manager; paired with a photo-editing program (Corel Photo-Paint), a font manager and several other pieces of software, it was also part of the first all-in-one graphics suite.
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.
CorelDraw Graphics Suite 2019 for Mac OS X was released on March 12, 2019, after an 18-year absence (the last version for OS X was version 11, released in 2001).
With version 6, CorelDraw introduced the automation of tasks using a Corel proprietary scripting language, COREL Script. With version 10, support for VBA (Visual Basic for Applications) was introduced for scripting by what Corel calls now macros. Corel recommends to no longer use the COREL Script language but only VBA.
In its first versions, the CDR file format was a completely proprietary file format primarily used for vector graphic drawings, recognizable by the first two bytes of the file being "WL". Starting with CorelDraw 3, the file format changed to a Resource Interchange File Format (RIFF) envelope, recognizable by the first four bytes of the file being "RIFF", and a "CDR*vrsn" in bytes 9 to 15, with the asterisk "*" being just a blank in early versions. Beginning with CorelDraw 4 it included the version number of the writing program in hexadecimal ("4" meaning version 4, "D" meaning version 14). The actual data chunk of the RIFF remains a Corel proprietary format.
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 (CDRFvrsn), and a root.dat with CorelDraw X6, where the bytes 9 to 15 look slightly different -- "CDRGfver" in a file created with X6. "F" was the last valid hex digit, and the "fver" now indicates that the letter before no longer represents a hex digit.
There is no publicly available CDR file format specification.
Other CorelDraw file formats include CorelDraw Compressed (CDX), CorelDraw Template (CDT) and Corel Presentation Exchange (CMX).
CDR file format import is partially or fully supported in following applications:
Adobe Illustrator - CorelDraw 5, 6, 7, 8, 9, 10
Corel PaintShop Photo Pro
Corel WordPerfect Office
Inkscape with UniConvertor installed; partial support
LibreOffice with libcdr installed - CorelDraw 7 to X3
Adobe FreeHand - CorelDraw 7, 8
Microsoft Visio 2002 - CorelDraw! drawing file versions 3.0, 4.0, 5.0, 6.0 and 7.0 (.cdr), Corel Clipart (.cmx)
sK1 - partial support
Xara Designer Pro and Xara Photo & Graphic Designer - early versions of CorelDraw CDR and CMX.
In December 2006 the sK1 open-source project team started to reverse-engineer the CDR format. The results and the first working snapshot of the CDR importer were presented at the Libre Graphics Meeting 2007 conference taking place in May 2007 in Montreal (Canada). Later on the team parsed the structure of other Corel formats with the help of the open source CDR Explorer. 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 UniConvertor, a command line open source tool which supports conversion from CorelDraw ver.7-X4 formats to other formats.
