47-464: 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

94-470: A ttcf table that allows access to the fonts within the collection by pointing to individual headers for each included font. The fonts within a collection share the same glyph-outline table, though each font can refer to subsets within those outlines in its own manner, through its cmap , name and loca tables. Collection files bear a .ttc filename extension. In classic Mac OS and macOS, TTC has file type ttcf . The suitcase format for TrueType

141-515: A " smart font " technology, named TrueType Open in 1994, later renamed to OpenType in 1996 when it merged support of the Adobe Type 1 glyph outlines. Opentype now contains all of the same functionality of Apple TrueType and Apple TrueType GX. TrueType has long been the most common format for fonts on classic Mac OS , Mac OS X , and Microsoft Windows , although Mac OS X and Microsoft Windows also include native support for Adobe's Type 1 format and

188-511: 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 13). 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

235-520: 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] Error: {{Lang}}: invalid parameter: |itallic= ( help ) library is used in LibreOffice starting from version 3.6, and thanks to public API it can be freely used by other applications. CDR file format import is partially or fully supported in following applications: TrueType TrueType

(24.0-24.2) MacOS (24.3) or MacOS 12, 13 (25) † CorelDraw 10 to X4 can open files of version 3 and later, but certain features may not be supported. ‡ The list of file formats that CorelDraw 10 to X4 can write may not be complete in this table. CorelDRAW was originally developed for Microsoft Windows 2.1 , and versions existed for Windows 3.1x , CTOS , OS/2 , and Power Macintosh . With

329-678: A new release for Apple silicon . A related web app and iPad app offers collaboration and markup online. In 2024, a new trial version was released available directly in the browser. With version 6, Corel introduced task automation using a proprietary scripting language, Corel SCRIPT. Support for VBA ( Visual Basic for Applications ) macros was added in version 9, and Corel SCRIPT was eventually deprecated. Support for VSTA ( Microsoft Visual Studio Tools for Applications ) has been integrated in Windows versions since X5, and currently requires Visual Studio 2017. Version 2019 added Javascript as an option for cross-platform scripting with MacOS support; however,

376-402: A regular TrueType font or an OpenType font with TrueType outlines. Windows end user defined character editor (EUDCEDIT.EXE) creates TrueType font with name EUDC.TTE. An OpenType font with PostScript outlines must have an .otf extension. In principle an OpenType font with TrueType outlines may have an .otf extension, but this has rarely been done in practice. In classic Mac OS and macOS, OpenType

423-543: 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, Corel Capture, and several other pieces of software, it was also part of the first all-in-one graphics suite. PowerMac PowerMac PowerMac Vista, 7, 8 For the first time, OpenType versions of Helvetica, Frutiger, Futura and Garamond #3 font families (32 fonts total) from Linotype foundry are included instead of

470-888: A small team of Ukrainian professionals in prepress , it was unambiguously focused on full support for PostScript , PDF , CMYK color model and color management at the expense of developing some advanced functions for illustrators . Informally the project is positioned as a free open source alternative to the commercial CorelDRAW . Compared to Inkscape , sK1 has a limited feature set, adequate for simple sketching, while its user interface remains clean. Drawable objects include circles and ellipses, rectangles, text, Bezier curves, and straight lines. Those can be transformed in typical manners and aligned in multiple ways. On 19 November 2006, On 19 November 2006, Bernhard Reiter and Bernhard Herzog asked Ihor Novikov to join Skencil development, stalled since 2005. On 31 October 2010, Skencil 1.0 alpha

517-604: Is an outline font standard developed by Apple in the late 1980s as a competitor to Adobe 's Type 1 fonts used in PostScript . It has become the most common format for fonts on the classic Mac OS , macOS , and Microsoft Windows operating systems. The primary strength of TrueType was originally that it offered font developers a high degree of control over precisely how their fonts are displayed, right down to particular pixels , at various font sizes. With widely varying rendering technologies in use today, pixel-level control

564-457: Is no longer certain in a TrueType font. TrueType was known during its development stage, first by the codename "Bass" and later on by the codename "Royal". The system was developed and eventually released as TrueType with the launch of Mac System 7 in May 1991. The initial TrueType outline fonts, four-weight families of Times Roman , Helvetica , Courier , and the pi font "Symbol" replicated

611-463: Is not possible to convert Type 1 losslessly to the TrueType format, although in practice it is often possible to do a lossless conversion from TrueType to Type 1. TrueType systems include a virtual machine that executes programs inside the font, processing the " hints " of the glyphs , in TrueType called “instructions”. These distort the control points which define the outline, with the intention that

658-458: Is now included, and MacOS is supported, requiring 10.12 (Sierra) or better. (22) 8.1, 10, MacOS Features include new AI-assisted PowerTRACE, bitmap upsampling, and bitmap artifact compression removal; new Stylized effects such as Pastel and Woodcut; nondestructive (lens) bitmap effects; another edge-finding mask tool; improved search and replace; and sliders to adjust OpenType variable fonts (Windows only). (23) MacOS A mid-year update added

705-605: Is one of several formats referred to as data-fork fonts, as they lack the classic Mac resource fork. TrueType Collection (TTC) is an extension of TrueType format that allows combining multiple fonts into a single file, creating substantial space savings for a collection of fonts with many glyphs in common. They were first available in Chinese, Japanese, and Korean versions of Windows, and supported for all regions in Windows 2000 and later. Classic Mac OS included support of TTC starting with Mac OS 8 .5. A TrueType Collection file begins with

752-399: Is used on classic Mac OS and macOS. It adds additional Apple-specific information. Like TTC, it can handle multiple fonts within a single file. But unlike TTC, those fonts need not be within the same family. Suitcases come in resource-fork and data-fork formats. The resource-fork version was the original suitcase format. Data-fork-only suitcases, which place the resource fork contents into

799-512: The OpenType extension to TrueType (since Mac OS X 10.0 and Windows 2000 ). While some fonts provided with the new operating systems are now in the OpenType format, most free or inexpensive third-party fonts use plain TrueType. Increasing resolutions and new approaches to screen rendering have reduced the requirement of extensive TrueType hinting. Apple's rendering approach on macOS ignores almost all

846-521: 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

893-612: The Bitstream counterparts. All but Garamond are in OpenType Pro format. Scripting is now also permitted in Visual Studio Tools for Applications . Corel X7 introduced 30-day and 365-day rentals (subscriptions) as an alternative to buying a perpetual license. Corel Content Exchange, an online source for fonts, fill patterns and other materials, required continuing payments for access to the full range of content. MacOS An online app

940-456: 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 CDR Explorer. Export into CDR and CMX file formats was presented at the Libre Graphics Meeting 2019 conference taking place in May 2019 in Saarbrücken (Germany). Since the project was started by

987-518: The Laserwriter II, Apple developed fonts like ITC Bookman and ITC Chancery in TrueType format. All of these fonts could now scale to all sizes on screen and printer, making the Macintosh System 7 the first OS to work without any bitmap fonts. The early TrueType systems — being still part of Apple's QuickDraw graphics subsystem — did not render Type 1 fonts on-screen as they do today. At

1034-632: 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). In December 2006,

1081-491: The TrueType hinting virtual machine were patented by Apple, a fact not mentioned in the TrueType standards. (Patent holders who contribute to standards published by a major standards body such as ISO are required to disclose the scope of their patents, but TrueType was not such a standard.) FreeType 2 included an optional automatic hinter to avoid the patented technology, but these patents have now expired so FreeType 2.4 now enables these features by default. The outlines of

1128-521: The Type 1 format was open for anyone to use. Meanwhile, in exchange for TrueType, Apple got a license for TrueImage , a PostScript -compatible page-description language owned by Microsoft that Apple could use in laser printing . This was never actually included in any Apple products when a later deal was struck between Apple and Adobe, where Adobe promised to put a TrueType interpreter in their PostScript printer boards. Apple renewed its agreements with Adobe for

1175-489: The backing store of characters necessary for spell checkers and text searching. However, the lack of user-friendly tools for making TrueType GX fonts meant there were no more than a handful of GX fonts. Much of the technology in TrueType GX, including variations and substitution, lives on as AAT ( Apple Advanced Typography ) in macOS . Few font-developers outside Apple attempt to make AAT fonts; instead, OpenType has become

1222-638: The best import support for CorelDraw file formats among open source software programs. The sK1 project also developed the UniConvertor, a command line open source tool which supports conversion from CorelDraw ver.7-X4 formats (CDR/CDT/CCX/CDRX/CMX) to other formats. UniConvertor is also used in the Inkscape and Scribus open source projects as an external tool for importing CorelDraw files. In 2007, Microsoft blocked CDR file format in Microsoft Office 2003 with

1269-463: The built-in IDE does not support it as of 2020. 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

1316-419: The characters (or glyphs ) in TrueType fonts are made of straight line segments and quadratic Bézier curves . These curves are mathematically simpler and faster to process than cubic Bézier curves, which are used both in the PostScript -centered world of graphic design and in Type 1 fonts. However, most shapes require more points to describe with quadratic curves than cubics. This difference also means that it

1363-424: The core fonts being bundled with PostScript equipment at the time. This included the fonts that are standard with Windows to this day: Times New Roman (compatible with Times Roman), Arial (compatible with Helvetica) and Courier New (compatible with Courier). In this context, "compatible" means two things. On an aesthetic level, it means that the fonts are similar in appearance. On a functional level, it means that

1410-646: The data fork, were first supported in macOS. A suitcase packed into the data-fork-only format has the extension dfont . In the PostScript language, TrueType outlines are handled with a PostScript wrapper as Type 42 for name-keyed or Type 11 for CID-keyed fonts. SK1 (program) sK1 is an open-source, cross-platform illustration program that seeks to be a substitute for professional proprietary software like CorelDRAW or Adobe Illustrator . Unique project features are CorelDRAW formats importers, tabbed multiple document interface, Cairo -based engine, and color management. A small team led by Igor Novikov started

1457-548: The dominant sfnt format, and all of the font variation technology is the de facto standard today in OpenType Variations. To ensure its wide adoption, Apple licensed TrueType to Microsoft for free. Microsoft added TrueType into the Windows 3.1 operating environment. In partnership with their contractors, Monotype Imaging , Microsoft put a lot of effort into creating a set of high quality TrueType fonts that were compatible with

1504-462: The edges of fonts at the expense of a slight blurring, and more recently subpixel rendering (the Microsoft implementation goes by the name ClearType ), which exploits the pixel structure of LCD based displays to increase the apparent resolution of text. Microsoft has heavily marketed ClearType, and sub-pixel rendering techniques for text are now widely used on all platforms. Microsoft also developed

1551-438: The font developer to make major changes (e.g., the point at which the entire font's main stems jump from 1 to 2 pixels wide) most of the way through development. Creating a very well-instructed TrueType font remains a significant amount of work, despite the increased user-friendliness of programs for adding instructions to fonts. Many TrueType fonts therefore have only rudimentary instructions, or have them automatically applied by

1598-447: The font editor, with results of various quality. The TrueType format allows for the most basic type of digital rights management  – an embeddable flag field that specifies whether the author allows embedding of the font file into things like PDF files and websites. Anyone with access to the font file can directly modify this field, and simple tools exist to facilitate modifying it (obviously, modifying this field does not modify

1645-400: The font license and does not give extra legal rights). These tools have been the subject of controversy over potential copyright issues. Apple has implemented a proprietary extension to allow color .ttf files for its emoji font Apple Color Emoji . A basic font is composed of multiple tables specified in its header. A table name can have up to 4 letters. A .ttf extension indicates

1692-448: The font), and encapsulation of code into functions. Special instructions called delta instructions are the lowest level control, moving a control point at just one pixel size. The hallmark of effective TrueType glyph programming techniques is that it does as much as possible using variables defined just once in the whole font (e.g., stem widths, cap height , x-height ). This means avoiding delta instructions as much as possible. This helps

1739-476: The fonts have the same character widths. This allows documents which have been typeset in one font to be changed to the other, without reflow . Microsoft and Monotype technicians used TrueType's hinting technology to ensure that these fonts did not suffer from the problem of illegibility at low resolutions, which had previously forced the use of bitmapped fonts for screen display. Subsequent advances in technology have introduced first anti-aliasing, which smooths

1786-496: The hints in a TrueType font, while Microsoft's ClearType ignores many hints, and according to Microsoft, works best with "lightly hinted" fonts. The FreeType project of David Turner has created an independent implementation of the TrueType standard (as well as other font standards in FreeType 2). FreeType is included in many Linux distributions. Until May 2010, there were potential patent infringements in FreeType 1 because parts of

1833-598: The launch of TrueType GX in 1994, with additional tables in the sfnt which formed part of QuickDraw GX . This offered powerful extensions in two main areas. First was font axes (today known as variations), for example allowing fonts to be smoothly adjusted from light to bold or from narrow to extended — competition for Adobe's " multiple master " technology. Second was Line Layout Manager, where particular sequences of characters can be coded to flip to different designs in certain circumstances, useful for example to offer ligatures for "fi", "ffi", "ct", etc. while maintaining

1880-405: The operating system, it became a de facto standard for anyone involved in desktop publishing . Anti-aliased rendering, combined with Adobe applications' ability to zoom in to read small type, and further combined with the now open PostScript Type 1 font format, provided the impetus for an explosion in font design and in desktop publishing of newspapers and magazines. Apple extended TrueType with

1927-492: The original PostScript fonts of the Apple LaserWriter. Apple also replaced some of their bitmap fonts used by the graphical user-interface of previous Macintosh System versions (including Geneva, Monaco and New York) with scalable TrueType outline-fonts. For compatibility with older systems, Apple shipped these fonts, a TrueType Extension and a TrueType-aware version of Font/DA Mover for System 6 . For compatibility with

1974-523: The project in 2003, based on the existing open source vector graphics editor Skencil . sK1 is a fork of the Skencil 0.6.x series which used Tk widgets for the user interface (this version had been dropped by the main Skencil developers who were working on a branch of the program based on GTK+ ). In 2007 the sK1 team reverse-engineered the CorelDRAW (CDR) format. The results and the first working snapshot of

2021-631: The rasterizer produce fewer undesirable features on the glyph. Each glyph's instruction set takes account of the size (in pixels) at which the glyph is to be displayed, as well as other less important factors of the display environment. Although incapable of receiving input and producing output as normally understood in programming, the TrueType instruction language does offer the other prerequisites of programming languages: conditional branching (IF statements), looping an arbitrary number of times (FOR- and WHILE-type statements), variables (although these are simply numbered slots in an area of memory reserved by

2068-408: The release of Corel Linux , CorelDRAW 9 was released with package support for Debian and Red Hat-based Linux . Version 11 was released for Mac OS X in 2001, but was then discontinued on both Linux and Mac. CorelDRAW was available only for Windows until the 2019 version became the first to support macOS. As of 2021, CorelDRAW Graphics Suite supports Windows 10 , Windows 11 , and macOS , including

2115-497: The release of Service Pack 3 for Office 2003. Microsoft later apologized for inaccurately blaming the CDR file format and other formats for security problems in Microsoft Office and released some tools for solving this problem. 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

2162-537: The time, many users had already invested considerable money in Adobe's still proprietary Type 1 fonts. As part of Apple's tactic of opening the font format versus Adobe's desire to keep it closed to all but Adobe licensees, Apple licensed TrueType to Microsoft . When TrueType and the license to Microsoft was announced, John Warnock , co-founder and then CEO of Adobe, gave an impassioned speech in which he claimed Apple and Microsoft were selling snake oil , and then announced that

2209-504: The use of PostScript in its printers, resulting in lower royalty payments to Adobe, who was beginning to license printer controllers capable of competing directly with Apple's LaserWriter printers. Part of Adobe 's response to learning that TrueType was being developed was to create the Adobe Type Manager software to scale Type 1 fonts for anti-aliased output on-screen. Although ATM initially cost money, rather than coming free with
