CorelDRAW

CorelDraw (styled CorelDRAW) is a vector graphics editor developed and marketed by Corel Corporation. It is also the name of Corel's Graphics Suite, which includes additionally 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 2018 (equivalent to version 20), and was released in April 10, 2018[1]. CorelDraw is designed to edit two-dimensional images such as logos and posters.

History

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.

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 .[31] The latest version, 2018, was released on 11 April 2018.

Versions for Mac OS and Mac OS X were at one time available, but due to poor sales these were discontinued. The last port for Linux was version 9 (released in 2000, it did not run natively; instead, it used a modified version of Wine to run) and the last version for OS X was version 11 (released in 2001). Also, up until version 5, CorelDraw was developed for Windows 3.1x, CTOS and OS/2.

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

Structure
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 in early versions just a blank.[33] 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 does no longer stand for a hex digit.

There is no publicly available CDR file format specification.[34][35]

Other CorelDraw file formats include CorelDraw Compressed (CDX), CorelDraw Template (CDT)[36] and Corel Presentation Exchange (CMX).[37]
