Expand description

TIFF compression scheme identifiers.

We support JPEG (value 7) and JPEG 2000 (value 33003) compression. Other compression schemes will result in HTTP 415 Unsupported Media Type.

Variants§

§

None = 1

No compression

§

Lzw = 5

LZW compression (not supported)

§

OldJpeg = 6

“Old-style” JPEG (not supported, rarely used)

§

Jpeg = 7

JPEG compression (supported)

§

Deflate = 8

Deflate/zlib compression (not supported)

§

AdobeDeflate = 32_946

Adobe Deflate (not supported)

§

Jpeg2000 = 33_003

JPEG 2000 (supported)
