About formats

CCX (Corel Compressed Exchange) is a compressed vector clipart format developed by Corel Corporation, introduced alongside CorelDRAW 5 in 1994. The format is essentially a compressed variant of CMX (Corel Presentation Exchange), packaging vector artwork, embedded bitmaps, and metadata into a smaller file suitable for distribution on CD-ROM clipart collections and online galleries. CCX files use the same underlying data structure as CMX but apply compression to reduce storage requirements — an important consideration during the 1990s when clip art libraries containing thousands of images shipped on capacity-limited media. Corel distributed vast collections of CCX clipart with CorelDRAW suites, and the format became synonymous with the extensive ready-made graphic libraries that distinguished Corel's product offerings. The artwork stored in CCX files ranges from simple geometric shapes to detailed illustrations, covering categories like business, nature, people, symbols, borders, and decorative elements. One advantage is compact storage — compression allows large clipart libraries to occupy significantly less disk space than equivalent uncompressed vector files. The ready-to-use nature of CCX content is another strength, providing designers with drag-and-drop artwork that scales cleanly to any size without quality loss, inheriting the resolution independence of the underlying vector data. While the format saw its peak usage during the CorelDRAW 5 through 12 era, CCX files remain openable in current versions of CorelDRAW and can be converted to modern formats.

OTB (Over-the-Air Bitmap) is a monochrome image format developed by Nokia as part of their Smart Messaging specification in 1997, designed for transmitting small graphics — operator logos, group graphics, and picture messages — to Nokia mobile phones via SMS. OTB files contain 1-bit (black and white) images at small fixed resolutions, typically 72x14 pixels for operator logos and 72x28 pixels for group graphics, encoded in a compact binary format suitable for embedding within the payload of SMS text messages. The format uses a simple structure: a header byte indicating whether the image is an operator logo or group graphic, width and height values, and the raw bitmap data where each bit represents one pixel packed eight per byte. The extremely tight format — designed to fit within a single SMS message (140 bytes maximum payload, shared with addressing overhead) — reflects the severe constraints of mobile communication in the late 1990s. Nokia's Smart Messaging system was one of the first commercial implementations of rich content delivery to mobile phones, and OTB images represented the entire visual content capability of Nokia handsets before MMS and mobile data browsing arrived. One advantage is the format's historical role as a pioneer of mobile visual messaging: OTB images were among the first graphics that ordinary consumers could send to each other's phones, predating MMS, camera phones, and smartphones by nearly a decade. The format's minimal footprint is another characteristic — entire images fit in a few dozen bytes, reflecting an era of extreme bandwidth constraints. OTB files are supported by ImageMagick, various Nokia phone management tools, and specialty mobile format utilities.
