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.

AZW3, also known as Kindle Format 8 (KF8), is Amazon's advanced ebook format introduced in November 2011 alongside the first Kindle Fire tablet. It replaced the older MOBI-based AZW format with a substantially more capable layout engine built on HTML5 and CSS3 subsets, enabling fixed layouts, embedded fonts, SVG graphics, drop caps, and other typographic refinements that were impossible in earlier Kindle formats. Internally, an AZW3 file packages content in a structure derived from EPUB, wrapped in Amazon's proprietary Palm database container with optional DRM protection. The format supports both reflowable text for novels and fixed-layout pages for comics, cookbooks, and children's titles. One major advantage is rich formatting fidelity — publishers can produce visually sophisticated ebooks with complex page designs, nested tables, and precise font control that render consistently across the Kindle ecosystem. Another strength is backward compatibility: AZW3 files can bundle a MOBI fallback section so older Kindle hardware still displays the content, even without full KF8 rendering. The format integrates tightly with Amazon's Kindle platform, supporting features like X-Ray, Whispersync page tracking, and in-book dictionary lookups across millions of devices and apps worldwide.
