Updated a bit ....
https://www.dpreview.com/forums/post/5394197 - see for LZW patent, I tested
rgba-float
project rendering one frame into LZW-compressed tiff, and it worked, at least
I can see image/alpha in GIMP (2.10.18).
I wonder how many tiff readers today ready to deal with lzma2 compressed tiffs?
I wonder if I should try to add png compression level to GUI :}

I tried few more compression schemas from libtiff 4.0.10 tiff.h:
#define TIFFTAG_COMPRESSION 259 /* data compression technique */
#define COMPRESSION_NONE 1 /* dump mode */
#define COMPRESSION_CCITTRLE 2 /* CCITT modified Huffman RLE */
#define COMPRESSION_CCITTFAX3 3 /* CCITT Group 3 fax encoding */
#define COMPRESSION_CCITT_T4 3 /* CCITT T.4 (TIFF 6 name) */
#define COMPRESSION_CCITTFAX4 4 /* CCITT Group 4 fax encoding */
#define COMPRESSION_CCITT_T6 4 /* CCITT T.6 (TIFF 6 name) */
#define COMPRESSION_LZW 5 /* Lempel-Ziv & Welch */
#define COMPRESSION_OJPEG 6 /* !6.0 JPEG */
#define COMPRESSION_JPEG 7 /* %JPEG DCT compression */
#define COMPRESSION_T85 9 /* !TIFF/FX T.85 JBIG
compression */
#define COMPRESSION_T43 10 /* !TIFF/FX T.43 colour
by layered JBIG compression */
#define COMPRESSION_NEXT 32766 /* NeXT 2-bit RLE */
#define COMPRESSION_CCITTRLEW 32771 /* #1 w/ word alignment */
#define COMPRESSION_PACKBITS 32773 /* Macintosh RLE */
#define COMPRESSION_THUNDERSCAN 32809 /* ThunderScan RLE */
/* codes 32895-32898 are reserved for ANSI IT8 TIFF/IT <[email protected]) */
#define COMPRESSION_IT8CTPAD 32895 /* IT8 CT w/padding */
#define COMPRESSION_IT8LW 32896 /* IT8 Linework RLE */
#define COMPRESSION_IT8MP 32897 /* IT8 Monochrome picture */
#define COMPRESSION_IT8BL 32898 /* IT8 Binary line art */
/* compression codes 32908-32911 are reserved for Pixar */
#define COMPRESSION_PIXARFILM 32908 /* Pixar companded 10bit LZW */
#define COMPRESSION_PIXARLOG 32909 /* Pixar companded 11bit ZIP */
#define COMPRESSION_DEFLATE 32946 /* Deflate compression */
#define COMPRESSION_ADOBE_DEFLATE 8 /* Deflate compression,
as recognized by Adobe */
/* compression code 32947 is reserved for Oceana Matrix <[email protected]> */
#define COMPRESSION_DCS 32947 /* Kodak DCS encoding */
#define COMPRESSION_JBIG 34661 /* ISO JBIG */
#define COMPRESSION_SGILOG 34676 /* SGI Log Luminance RLE */
#define COMPRESSION_SGILOG24 34677 /* SGI Log 24-bit packed */
#define COMPRESSION_JP2000 34712 /* Leadtools JPEG2000 */
#define COMPRESSION_LERC 34887 /* ESRI Lerc codec:
https://github.com/Esri/lerc */
/* compression codes 34887-34889 are reserved for ESRI */
#define COMPRESSION_LZMA 34925 /* LZMA2 */
#define COMPRESSION_ZSTD 50000 /* ZSTD: WARNING not registered
in Adobe-maintained registry */
#define COMPRESSION_WEBP 50001 /* WEBP: WARNING not registered
in Adobe-maintained registry */
Sadly, only deflate worked with 32-bit floating point session.
Others complained like
FileTIFF: Compression scheme 32908 scanline encoding is not implemented.
Also, GIMP complained a bit, but allow me to open image anyway:
tiff_io_warning: [TIFFReadDirectory] Sum of Photometric type-related color
channels and ExtraSamples doesn't match SamplesPerPixel. Defining non-color
channels as ExtraSamples.
tiff_io_warning: [TIFFReadDirectory] Sum of Photometric type-related color
channels and ExtraSamples doesn't match SamplesPerPixel. Defining non-color
channels as ExtraSamples.
tiff_io_warning: [TIFFReadDirectory] Sum of Photometric type-related color
channels and ExtraSamples doesn't match SamplesPerPixel. Defining non-color
channels as ExtraSamples.
tiff_io_warning: [TIFFReadDirectory] Sum of Photometric type-related color
channels and ExtraSamples doesn't match SamplesPerPixel. Defining non-color
channels as ExtraSamples.
bps: 32
load_contiguous
bytes_per_pixel: 16, format: 16
Probably for other compression schemas differet, non-scanline method of calling
libtiff must be used?
Also, a bit of nipicking (?) but Cinelerra doesn' show single-frame rendering
correctly in stats:
** rendered 0 frames in 14.170 secs, 0.000 fps
Render::render_single: Session finished.
** rendered 355 frames in 249.619 secs, 1.422 fps
Render::render_single: Session finished.
** rendered 0 frames in 3.640 secs, 0.000 fps
Shouldn't it be 1 frame, at least?
