RGBO to FICTIONBOOK conversion is the process of transforming images stored in the RGBO raster format (which encodes Red, Green, Blue and an opacity/alpha channel) into the FB2 (FictionBook) e-book format by embedding or converting image data and metadata into a structured XML-based FB2 document. This conversion typically packages images and text content into FB2's XML containers so image-heavy documents or illustrated books originally in RGBO form can be read in FictionBook-compatible readers.

RGBO files typically use a proprietary MIME type suited for specific reading software, often with limited codec support. FICTIONBOOK (FB2) files use the application/fb2+xml MIME type and are XML structured, making them ideal for eBook readers and applications that support advanced formatting and metadata. Converting RGBO to FB2 expands usability across platforms.
The FICTIONBOOK (.FB2) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like RGBO.
While specific technical details aren't available here, FICTIONBOOK files generally serve the purpose of storing image effectively within their domain.

RGBO is a less common eBook format primarily used in niche applications, while FICTIONBOOK (FB2) is an XML-based format widely supported by many eBook readers. FB2 offers better metadata handling and is easier to parse for digital libraries compared to RGBO, which can be more restrictive in terms of device compatibility.
Keep individual RGBO images under 10–20 MB for faster processing; very large bitmaps slow conversions and may exceed memory limits.
To preserve visual quality, prefer lossless embedding (PNG) inside FB2; if file size matters, choose moderate JPEG compression (quality 70–85).
For multi-page or multi-image books, batch-convert and then merge using a tool that preserves image order and FB2 sequence tags.
RGBO is primarily an image-oriented raster container; text must be OCRed or provided separately because FB2 is XML text-centric—automatic text extraction from RGBO is limited.
