About formats

PLASMA is a procedural pseudo-format built into ImageMagick, the open-source image processing suite first released by John Cristy at DuPont on August 1, 1990. Rather than storing pixel data in a file, the PLASMA format algorithmically generates fractal plasma images on the fly using a recursive midpoint displacement algorithm: the image corners are seeded with random colors, then the midpoints of each edge and the center are assigned interpolated colors with random perturbation, and this process recurses until every pixel has been filled. The result is a smoothly varying, cloud-like pattern of blended colors that is unique with each generation. PLASMA images are invoked via ImageMagick's command-line syntax (e.g., convert -size 640x480 plasma: output.png) and the output can be saved to any supported raster format. The generation parameters — seed value, recursion depth, and color space — can be controlled to produce everything from soft pastel gradients to vivid high-contrast turbulence. One advantage is creative utility: PLASMA-generated images serve as excellent starting points for texture synthesis, background generation, displacement maps for 3D rendering, and procedural material creation in game development and digital art workflows. The format's integration into ImageMagick's processing pipeline provides another practical benefit — generated plasma images can be directly piped through ImageMagick's extensive image processing operations (color manipulation, distortion, compositing, morphology) without intermediate file I/O, enabling efficient procedural texture workflows entirely from the command line.

RB is the native ebook format of the Rocket eBook, one of the first commercially available dedicated e-reading devices, developed by NuvoMedia and released in October 1998. Founded by Martin Eberhard and Marc Tarpenning — who later co-founded Tesla Motors — NuvoMedia designed the Rocket eBook as a handheld device with a reflective LCD screen, capable of storing approximately ten books in its internal memory. The RB format packages HTML-based content along with embedded images, metadata, and a table of contents into a single binary container optimized for the device's limited hardware. Content was purchased and downloaded through NuvoMedia's RocketLibrarian desktop software. A notable advantage of the format was its early support for bookmarking, annotation, dictionary lookups, and adjustable font sizing — features now standard on modern e-readers but revolutionary in the late 1990s. The Rocket eBook demonstrated viable commercial demand for dedicated reading devices, paving the way for subsequent platforms from Sony, Amazon, and others. NuvoMedia was acquired by Gemstar-TV Guide International in 2000, which discontinued the device line in 2003. While RB files are largely a historical curiosity today, they can be converted to modern formats using ebook management tools, and the format remains significant as a pioneering chapter in the evolution of digital reading.

Frequently Asked Questions

Why convert PLASMA to RB?

RB embeds the image in a structured document layout, making PLASMA content easy to distribute, annotate, and print anywhere.

What programs open RB files?

View RB files using the appropriate reader application — free options exist for every major operating system and mobile platform.

Where do PLASMA files come from?

PLASMA images are generated algorithmically as fractal art. They produce colorful patterns from mathematical formulas rather than capturing real scenes.

Which platforms are supported?

Every platform with a modern browser works — Windows, macOS, Linux, ChromeOS, iOS, and Android all run the PLASMA to RB converter perfectly.

How many files can I convert at a time?

You can upload and convert multiple PLASMA files to RB in a single session. Each conversion processes in parallel for faster results.
