CorelDraw (CorelDRAW style) is a vector graphics editor developed and marketed by Corel Corporation. This is also the name of Corel's Graphics Suite, which combines CorelDraw with Corel Photo-Paint bitmap-image editor and other graphical related programs (see below). The latest version is marketed as CorelDraw Graphics Suite 2018 (equivalent to version 20), and released on April 10, 2018. CorelDraw is designed for editing two-dimensional images such as logos and posters.

Histori
In 1987, Corel engineers Michel Bouillon and Pat Beirne undertook the development of a vector-based illustration program to be combined with their desktop publishing system. The program, CorelDraw, was originally released in 1989. CorelDraw 1.x and 2.x run under Windows 2.x and 3.0. CorelDraw 3.0 comes on its own with the release of Microsoft Windows 3.1. The inclusion of TrueType in Windows 3.1 transforms CorelDraw into a serious illustration program capable of using system-installed outline fonts without the need for third-party software such as Adobe Type Manager; paired with photo editing programs (Corel Photo-Paint), font management and some other software, it's also part of the first all-in-one graphics suite.

Features
Supported platforms
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, 2017, was released on April 11, 2017.
Versions for Mac OS and Mac OS X at one time are available, but because of poor sales this is discontinued. The last port for Linux is version 9 (released in 2000, it does not run natively, on the contrary, it uses a modified Wine version to run) and the final version for OS X is version 11 (released in 2001). Also, up to version 5, CorelDraw was developed for Windows 3.1x, CTOS and OS/2.
With version 6, CorelDraw introduces task automation using the proprietary Corel script language, COREL Script. With version 10, support for VBA (Visual Basic for Applications) was introduced for scripting by what Corel is now called macros . Corel advises to no longer use COREL Script language but only VBA.
CDR file format
Structure
In its first version, the CDR file format is a fully proprietary file format that is primarily used for vector graphics, recognizable by the first two bytes of the "WL" file. Starting with CorelDraw 3, the file format is converted to an envelope of Resource Interchange File Format (RIFF), identified by the first four bytes of the "RIFF" file, and "CDR * vrsn" in bytes 9 through 15, with the asterisk "*" in initial version, just empty. Starting with CorelDraw 4 it includes the version number of the hexadecimal writing program ("4" which means version 4, "D" which means version 14). The actual data deduction from the RIFF remains a Corel proprietary format.
From the active X4 (14) version, the CDR file is a ZIP-compressed directory of several files, including XML files and RIFF structured riffdata.cdr with the familiar version signature in X4 (CDREvrsn) and X5 (CDRFvrsn ), and a root.dat with CorelDraw X6, where bytes 9 through 15 look slightly different - "CDRGfver" in files created with X6. "F" is the last valid hex digit, and "fver" now indicates that the previous letter is no longer standing for hex digits.
There is no specification of the publicly available CDR file format.
Format file CorelDraw lainnya termasuk CorelDraw Compressed (CDX), CorelDraw Template (CDT) dan Corel Presentation Exchange (CMX).
Penggunaan file CDR di program lain
In December 2006 the open source project team sK1 started to reverse-engineer the CDR format. The first results and snapshots of the CDR importers were presented at the 2007 Libre Graphics Meeting that took place in May 2007 in Montreal (Canada). Then the team parses other Corel format structures with the help of open source CDR Explorer. In 2008, the sK1 project claims to have the best import support for CorelDraw file formats among open source software programs. The sK1 project also developed UniConvertor, a command-line open source tool that supports the conversion of CorelDraw ver.7-X4 (CDR/CDT/CCX/CDRX/CMX) formats to other formats. UniConvertor is also used in the open source project Inkscape and Scribus as an external tool for importing CorelDraw files.
In 2007, Microsoft blocked the CDR file format in Microsoft Office 2003 by releasing Service Pack 3 for Office 2003. Microsoft later apologized for not accurately blaming the CDR file format and other formats for security issues in Microsoft Office and released several tools to solve this problem..
In 2012, the LibreOffice/re-lab merge team is applying libcdr, a library for reading CDR files from v1 to X7 and recent CMX files. The library has extensive support for its forms and properties, including support for spot color and color management, and has basic support for text. The library provides an integrated converter to SVG, and a converter to OpenDocument is provided by the author package. The libcdr library is used in LibreOffice starting from version 3.6, and thanks to the public API it can be freely used by other apps.
