Scientific readers and browser explorer
The package exposes 33 explicit readers across microscopy, whole-slide, AFM and surface metrology, medical volumes, spectroscopy, detector, and raw numeric interchange. Numeric samples remain separate from RGB display pixels; range selection, palettes, slices, projections, and relief are explicit operations.
Ready.
Quantitative source values remain unchanged. Palette, stretch, scale, and relief affect only the streamed display pixels shown above.
The PNG is the current display rendering, not a converted scientific dataset.
Generated package reader surface
The package surface is broader than the interactive explorer above. The explorer currently wires only 5 readers; it does not claim to open every newly supported format. Applications can register any explicit reader export listed below.

Real public data
These research, university, and government collections publish ENVI, FITS, MRC, and CBF files. Large files should be downloaded before opening them above.
Direct directory of ENVI .hdr + .img reflectance cubes. Individual images range from about 951 MiB to 13 GiB.
The FITS Support Office publishes image, table, and conformance samples for testing FITS readers.
Browse NASA FITS samples ↗The CCP-EM mrcfile project maintains real MRC and CCP4 maps used to test MRC2014 readers.
Browse CCP-EM maps ↗Real PILATUS detector frames with x-CBF_BYTE_OFFSET compression for CBF compatibility testing.
Browse PSI CBF files ↗Five complete imaging-spectrometer products covering vegetation, cities, geology, calibration, and high-resolution data.
Browse free AVIRIS data ↗Cataloged ENVI .hdr + .bin products with 224 bands from roughly 400–2500 nm. Earthdata sign-in may be required.
ENVI .hdr + .dat flight scenes with 256 thermal-infrared bands from 7.5–12 µm.

FITS, MRC, and CBF examples are single-file downloads. For a paired ENVI example, download both numbered files and select them together above.

Open a single-file download: choose its FITS, MRC, or CBF tab, then select the downloaded file. Open an ENVI download: unpack the archive, choose its .hdr file under ENVI header, choose the matching .img, .bin, or .dat file under Associated binary, then click Open paired files. A browser may save a header as .hdr.txt; the explorer accepts that filename too. GSF is commonly exported from AFM/SPM software rather than distributed by institutional archives.
Scientific raster formats
GSF, ENVI, FITS, MRC, and CBF remain scientific datasets rather than photographic codecs. Their numeric samples use the same dataset API as OME-TIFF planes. FITS and MRC volumes share lazy cross-sections and bounded Z projections.
