About formats

RGF (Robot Graphics Format) is a simple monochrome bitmap image format used by LEGO Mindstorms EV3 programmable robotics kits, introduced with the EV3 system on September 1, 2013. RGF files store 1-bit (black and white) images designed for display on the EV3 Intelligent Brick's 178x128 pixel monochrome LCD screen. The format uses a minimal structure: a header containing the image width and height as binary values, followed by the pixel data where each bit represents one pixel (1 for black, 0 for white), packed eight per byte in row-major order. RGF images are used as custom display graphics in EV3 programs — students and hobbyists create them for robot status displays, user interfaces, splash screens, and animation frames shown on the brick's screen during program execution. The images are typically designed using LEGO's EV3 software (which includes a built-in image editor) or converted from other formats using community tools. RGF fits within LEGO's broader educational robotics platform, where the Mindstorms system teaches programming, engineering, and computational thinking to students worldwide. One advantage is the format's role in educational technology: RGF provides a simple, concrete example of how digital images are represented as binary data — a concept that students working with Mindstorms can directly observe by examining the file contents and seeing the corresponding image on the brick's screen. The format's simplicity makes it accessible for young programmers learning about file formats and binary data. RGF files can be created and converted using ImageMagick, the EV3 development environment, and community tools like ev3dev.

VIPS is the native file format of the libvips image processing library, originally developed by John Cupitt and Kirk Martinez at the National Gallery in London during the VASARI project (1989-1993) for high-resolution digitization and analysis of paintings. The VIPS format stores large images in a simple, memory-mappable layout: a header containing image dimensions, number of bands (channels), data type (8/16/32-bit integer, float, double, complex), color interpretation, resolution, and offset metadata, followed by the raw pixel data in band-interleaved format. This straightforward layout allows the operating system's virtual memory manager to map the file directly into address space, enabling libvips to process images much larger than available RAM by paging portions in and out as needed — a technique called demand-driven evaluation. VIPS files support images with any number of bands at any of the supported numeric types, accommodating everything from standard RGB photographs to hyperspectral datasets with hundreds of bands. One advantage is large-image performance: libvips's architecture processes images in small tiles evaluated on demand, meaning a 100,000 x 100,000 pixel image can be cropped, resized, sharpened, and saved without loading the entire image into memory — a capability that makes VIPS the engine behind image processing services handling millions of web images. The format's scientific heritage is another strength — the VASARI project required analyzing paintings at ultra-high resolution with multispectral imaging, and the VIPS format's support for arbitrary band counts and floating-point precision reflects these computational imaging origins. VIPS files are primarily used with the libvips library (available for C, Python, Ruby, and other languages) and can be converted to other formats via vips command-line tools or ImageMagick.

Frequently Asked Questions

Why convert RGF to VIPS?

RGF files have limited software support. Converting to VIPS ensures your images are accessible on all modern devices and platforms.

What programs open VIPS files?

VIPS files open in most image viewers and editors — including web browsers, system preview tools, Photoshop, GIMP, and Paint on Windows.

Why is RGF not widely supported?

RGF was designed exclusively for LEGO Mindstorms brick displays — a very niche educational robotics platform with its own proprietary graphics format.

How many files can I convert at a time?

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

Is my RGF data kept private?

Uploaded files are deleted immediately after conversion, and converted files are removed within 24 hours. Your data stays private and secure.
