SIXEL to RB conversion is the process of transforming an image encoded in the SIXEL graphics format (a raster graphics encoding historically used by DEC terminals and some printers) into the RB image format, producing an RB-compatible raster file. This conversion decodes SIXEL's run-length and color palette data into pixel data and then encodes those pixels according to RB's specification, preserving color and layout where possible.

SIXEL files typically use the image/sixel MIME type and are mainly used for terminal-based graphics. RB files utilize the image/rb MIME type and incorporate advanced codecs for improved compression. The conversion process involves decoding SIXEL raster data and encoding it into the RB format for optimized performance.
The RB (.RB) format is commonly used for ebook. Understanding its characteristics can be helpful when converting to or from other formats like SIXEL.
While specific technical details aren't available here, RB files generally serve the purpose of storing ebook effectively within their domain.

SIXEL is an older image format primarily used for terminal graphics, while RB is a more versatile and compressed format suited for modern image processing. SIXEL files tend to be larger and less optimized compared to RB, which provides better efficiency and broader application support.
Keep optimal file size: for best speed and fidelity, use SIXEL inputs under 10 MB when possible; very large SIXEL streams (tens of MB) can slow decoding and increase memory use.
Preserve quality: convert using a high color-depth RB output (24-bit) and low compression to minimize irreversible color loss from palette remapping.
Batch conversion: process multiple SIXEL files in a batch using command-line tools or an API to conserve overhead; limit concurrent conversions to avoid running out of memory.
Format limitation: SIXEL is palette/run-length oriented and can contain terminal-specific control sequences, so some terminal-specific metadata or interleaved controls may need stripping before accurate conversion.
