About formats

T11 (Type 11) is a PostScript font type defined by Adobe Systems as part of the CID-keyed font architecture, combining CID glyph addressing with TrueType outline data wrapped in a Type 42 PostScript shell. In Adobe's font type numbering, Types 9, 10, and 11 are CID-keyed counterparts to Types 1, 3, and 42 respectively — so Type 11 is essentially a CID-keyed Type 42, designed for TrueType fonts that contain very large glyph sets, particularly CJK (Chinese, Japanese, Korean) character collections. The format allows PostScript interpreters with TrueType rasterizer support to render CJK TrueType fonts while using CID numeric indexing instead of glyph names, which is critical for character sets numbering in the tens of thousands. Glyph outlines remain in native TrueType quadratic spline format, preserving the original hinting instructions, while the CID layer provides efficient glyph access and subsetting through CMap resources. One advantage is direct TrueType rendering quality — unlike converting TrueType outlines to PostScript cubics, Type 11 passes the original outlines to the rasterizer intact, preserving hand-tuned grid-fitting instructions. The CID indexing provides another benefit by supporting multiple encoding schemes (Unicode, national standards) mapped to the same glyph collection without data duplication. Type 11 fonts appear primarily in professional CJK print production and PDF document workflows where large TrueType-based character sets must be embedded in PostScript-derived output.

RGB is a raw (headerless) image format that stores pixel data as a flat sequence of red, green, and blue sample values with no container structure, compression, or metadata. Each pixel is represented by three consecutive bytes (in 8-bit mode) — one for red intensity, one for green, and one for blue — written in scanline order from the top-left corner of the image to the bottom-right. Because there is no header, the image dimensions and bit depth must be specified externally when reading the file. The format supports multiple bit depths: 8-bit (0-255 per channel), 16-bit (0-65535 per channel), and floating-point variants, with 8-bit being the most common. The RGB color model itself reflects how display hardware produces color — by mixing red, green, and blue light at varying intensities — and raw RGB files represent this model in its most direct digital form. With 8-bit channels, three bytes per pixel yield a 24-bit color palette capable of representing 16,777,216 distinct colors. One advantage is zero-overhead processing: without headers or compression to parse, raw RGB data can be memory-mapped, fed directly into GPU textures, or piped between processing stages with minimal latency — valuable in real-time imaging, scientific instrumentation, and computer vision pipelines where every millisecond matters. The format's universal simplicity provides another practical strength — any programming language can read or write raw pixel data with just basic file I/O, making it a reliable interchange format between custom software that may not share support for structured image containers. Raw RGB files are handled by ImageMagick, FFmpeg, and various scientific and graphics tools.

Frequently Asked Questions

Why convert T11 to RGB?

SGI RGB is used in professional 3D and VFX studios, particularly on IRIX workstations. Rendering T11 glyphs as RGB integrates typography into these pipelines.

How do I open an RGB file?

RGB files open in Photoshop, GIMP, ImageMagick, Blender, and professional compositing tools like Nuke. IRIX systems handle SGI RGB natively.

Is SGI RGB the same as raw RGB data?

No — SGI RGB is a specific image format (also called SGI or IRIS) with its own header and optional RLE compression, not simply raw pixel bytes.

Does RGB support alpha?

For alpha transparency, use the RGBA variant instead. The RGB format stores three color channels without a transparency component.

Is T11 to RGB free?

Yes, this conversion is entirely free on Convertio — cloud-based, no registration or installs.
