About formats

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.

DOT is the binary template format for Microsoft Word, using the same OLE2 compound document structure as DOC files. A DOT file contains a complete document framework — styles, page layout, margins, headers and footers, boilerplate text, macros, AutoText entries, toolbar customizations, and keyboard shortcuts — that serves as a reusable foundation for creating new documents with consistent formatting. When a user creates a new document based on a DOT template, Word generates a fresh untitled DOC pre-populated with the template's content and styling while leaving the original template file unmodified. The format supports every feature available in DOC, including complex formatting, embedded objects, form fields, and VBA macro code. The Normal.dot file holds particular significance as Word's global template, storing default styles, macros, and customizations that apply to all new blank documents. DOT templates became essential to enterprise document management, ensuring that legal contracts, business letters, technical reports, and corporate communications consistently adhered to organizational formatting standards. One advantage is brand and compliance consistency — distributing DOT files across an organization guarantees uniform document appearance without relying on individual users to manually configure styles and layouts. While the XML-based DOTX format has replaced DOT for modern workflows, the binary template format remains in use in environments requiring Word 97-2003 compatibility and in legacy template libraries.
