About formats

ODT (OpenDocument Text) is the word processing format defined by the OpenDocument Format (ODF) standard, developed by the OASIS technical committee and first published as ODF 1.0 on May 1, 2005, later adopted as international standard ISO/IEC 26300. An ODT file is a ZIP archive containing XML documents that describe text content, formatting styles, metadata, and settings using a vendor-neutral, royalty-free specification. The document body resides in content.xml with styling rules in styles.xml, while embedded images, fonts, and other resources are stored alongside in the package. The format supports rich word processing features including paragraph and character styles, tables, footnotes, tracked changes, table of contents generation, bibliography management, mail merge fields, and embedded vector and raster graphics. ODT serves as the native format for LibreOffice Writer, Apache OpenOffice Writer, and Calligra Words, and can be imported by Microsoft Word, Google Docs, and other commercial tools. One advantage is vendor independence — ODT is governed by an open standard rather than a single company, ensuring long-term document accessibility free from proprietary lock-in. This makes ODT particularly important for government agencies, educational institutions, and organizations with archival mandates. The XML-based architecture provides another strength, enabling programmatic document generation and processing using standard tools in any programming language.

Initial release: May 1, 2005
RGBO is a raw pixel data format designation used by ImageMagick, the open-source image processing suite first released in 1990, representing images as a flat sequence of Red, Green, Blue, and Opacity (inverted alpha) sample values with no header, container, or compression. The RGBO channel ordering specifies that the fourth channel is opacity rather than alpha — where alpha represents transparency (0 = transparent, max = opaque), opacity represents the inverse (0 = opaque, max = transparent). This distinction matters in compositing pipelines where the mathematical convention for the fourth channel varies between systems: some compositing models work with alpha (transparency), while older conventions including portions of ImageMagick's internal processing historically used opacity. RGBO files contain raw sample data at a user-specified bit depth (8-bit, 16-bit, or floating-point per channel), with pixels stored in scanline order. Because there is no header, the image dimensions, bit depth, and endianness must be specified externally when reading the file — typically via ImageMagick command-line arguments. One advantage is direct compatibility with processing pipelines that use the opacity convention: RGBO eliminates the need for channel inversion when interfacing with systems that expect opacity rather than alpha, preventing subtle compositing errors that occur when transparency conventions are mixed. The format's raw-data nature provides another practical benefit — with no encoding overhead, RGBO data can be memory-mapped, processed with SIMD instructions, or piped between processes with minimal latency. RGBO is primarily used within ImageMagick processing chains and can be converted to any other format using ImageMagick's extensive format support.

Frequently Asked Questions

Why convert ODT to RGBO?

RGBO stores SGI images with opacity — convert when document visuals need transparency in SGI workflows.

What is RGBO format?

RGBO is a variant of the SGI image format that stores RGB data with an opacity channel.

What opens RGBO files?

SGI-compatible tools, ImageMagick, and specialized graphics applications can process RGBO files.

Is ODT to RGBO free?

Yes — Convertio handles this conversion for free. Premium plans offer additional capacity for heavy users.

How quick is the process?

Cloud processing renders your image in seconds — no waiting for local software to do the heavy lifting.

Can I convert many files at once?

Yes — batch-upload your ODT documents and receive them all as RGBO files in a single pass.
