About formats

CMX (Corel Presentation Exchange) is a vector graphics exchange format developed by Corel Corporation, introduced with CorelDRAW 5 in September 1994. Designed as a cross-application interchange format within the Corel product suite, CMX stores vector objects, text, bitmaps, and rendering attributes in a structure accessible to CorelDRAW, Corel PHOTO-PAINT, Corel Presentations, and other Corel applications without requiring each program to understand the full CDR native format. The format uses a chunk-based architecture that encodes geometric primitives, fill patterns, outline properties, and color definitions in a standardized way, supporting both 16-bit and 32-bit variants. CMX gained significance beyond the Corel ecosystem through its adoption by third-party applications and its role in clipart distribution — many vector art collections from the mid-to-late 1990s shipped in CMX format. One advantage is interoperability within design workflows: CMX provided a practical bridge for moving vector content between different Corel applications while preserving visual fidelity, gradients, and transparency attributes. The format's inclusion of both vector and bitmap data within a single file is another strength, allowing complex mixed-media illustrations to be exchanged as self-contained units. Microsoft also added CMX import support to some Office applications, expanding the format's reach. While modern Corel applications primarily use CDR for native work and export to SVG, PDF, or EPS for interchange, CMX files from the CorelDRAW era remain widely encountered in legacy asset libraries.

SUN is a raster image format associated with Sun Microsystems workstations, encompassing both the Sun Raster format (.ras) and the Sun Icon format used for window system icons and cursors on SunOS and Solaris systems. Sun Raster files, identifiable by their 0x59a66a95 magic number, store bitmap images in 1-bit monochrome, 8-bit indexed color, 24-bit BGR, or 32-bit XBGR modes, with optional run-length encoding compression and a 32-byte header. The Sun Icon subset is a simpler text-based format used for small monochrome bitmaps — window icons, cursor images, and toolbar graphics — stored as C-language data arrays that could be directly compiled into X Window and SunView applications. These icon files begin with a comment block specifying width, height, and optionally hot spot coordinates (for cursor images), followed by hexadecimal pixel values in a format readable by both the C compiler and the iconedit tool. Sun workstations running SunOS and later Solaris were foundational platforms for Unix computing, networking, and the early internet, and the SUN image formats were integral to their graphical environments. One advantage is the format's dual text/binary nature: Sun Icons are valid C source code that can be #included directly into applications, a practical approach to resource embedding that predates modern asset management systems. The Sun Raster variant's simplicity provides another strength — the 32-byte header and straightforward encoding make it one of the easiest binary image formats to parse. SUN format files are supported by ImageMagick, GIMP, XnView, and Unix image viewing tools.
