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.

VIFF (Visualization Image File Format) is a scientific image format developed by Khoral Research (originally at the University of New Mexico), first appearing around 1990 with the Khoros visual programming environment for image processing and data visualization. VIFF files use a 1024-byte header followed by optional color map data, and the image data itself, with the header containing detailed specifications: data storage type (bit, byte, short, integer, float, double, complex), data encoding (none, CCITT Group 3/4), color space model (none, generic, RGB, HSI, CMYK, and others), and support for multi-band (multi-channel) images with arbitrary numbers of bands. The format accommodates one-dimensional signals, two-dimensional images, three-dimensional volumes, and location data (sparse pixel coordinates), making it versatile beyond simple image storage. VIFF was designed for the Khoros/VisiQuest visual dataflow programming environment, where users constructed image processing pipelines by connecting processing nodes in a graphical canvas — an approach that influenced later systems like AVS, MATLAB Simulink, and LabVIEW. One advantage is scientific data fidelity: VIFF supports the full range of numeric types used in scientific computing (including complex numbers and double-precision floats), stores multi-band datasets natively, and carries calibration metadata — making it suitable for remote sensing, medical imaging, and spectral analysis applications where generic image formats lose information. The format's connection to the Khoros visual programming paradigm provides another notable dimension — VIFF was the standard I/O format for one of the most influential early visual programming environments for scientific image analysis. VIFF files can be read by ImageMagick and legacy Khoros/VisiQuest installations.

Frequently Asked Questions

Why convert T11 to VIFF?

VIFF is used by the Khoros/VisiQuest visualization framework for scientific image analysis. Rendering T11 glyphs as VIFF integrates text into these workflows.

How do I open a VIFF file?

VIFF files are processed by Khoros/VisiQuest, ImageMagick, and XV image viewer. Some scientific visualization toolkits also support the format.

What kind of data can VIFF store?

VIFF supports multiple image bands, various bit depths, and complex data types — designed for flexible scientific visualization needs.

Is VIFF commonly used today?

VIFF is a niche format primarily found in academic and scientific visualization contexts. For general images, more common formats are preferred.

Is T11 to VIFF free?

Yes — Convertio handles this conversion at no cost, entirely cloud-based from any browser.
