and other TIFF tags as they are described in the TIFF documentation.
GeoTIFF tags:

GeoASCIIParams (string)
Read-only support for EXIF tags as they are described in the EXIF 2.2 documentation. See http://www.exif.org/
DNG tags as they are described in the DNG documentation. See http://www.adobe.com/br/products/dng/
Tags BlackLevel, DefaultCropOrigin and DefaultCropSize are incorrectly interpreted by libTIFF so they are ignored.
Raw image is loaded in place of the thumbnail image in the main IFD.
SubIFDCount IM_USHORT (1) [Number of subifds of the current image.]
SubIFDSelect IM_USHORT (1) [Subifd number to be readed. Must be set before reading image info.]
(other attributes can be obtained by using libTIFF directly using the Handle(1) function)
Comments:
LogLuv is in fact Y'+CIE(u,v), so we choose to always convert it to XYZ.
SubIFD is handled only for DNG.
Since LZW patent expired, LZW compression is enabled. LZW Copyright Unisys.
libGeoTIFF can be used without XTIFF initialization. Use Handle(1) to obtain a TIFF*.
Changes:
"tiff_jpeg.c" - commented "downsampled_output = TRUE" in 2 places.
New file "tif_config.h" to match our needs.
New file "tiff_binfile.c" that implement I/O rotines using imBinFile.

Internally the lines are arranged from top down to bottom.
Attributes:

Comments:
In fact ASCII is an expansion, not a compression, because the file will be larger than binary data.

Data Types: Byte
Color Spaces: RGB, MAP and Binary (Gray saved as MAP)
Compressions:
NONE - no compression [default]
Can have more than one image. But writing is limited to 5 images,
and all images must have different sizes and bpp.
Can have an alpha channel (only for RGB)
Internally the components are always packed.
Internally the lines are arranged from bottom up to top.
Attributes:
TransparencyIndex IM_BYTE (1)
Comments:
If the user specifies an alpha channel, the AND mask is loaded as alpha if
the file color mode does not contain the IM_ALPHA flag.
For MAP imagens, if the user does not specifies an alpha channel
the TransparencyIndex is used to initialize the AND mask when writing,
and if the user does specifies an alpha channel
the most repeated index with transparency will be the transparent index.
Although any size and common bpp can be used is recomended to use the typical configurations:
16x16, 32x32, 48x48, 64x64 or 96x96
2 colors, 16 colors, 256 colors, 24bpp or 32bpp

Color Spaces: Gray
Compressions:
NONE - no compression [default]
Only one image.
No alpha channel.
Internally the lines are arranged from top down to bottom.
Attributes:
Description (string)
Comments:
The format is very simple, inspired by PNM.
It was developed because PNM does not have support for INT and FLOAT.
Remeber that usually convolution operations use kernel size an odd number.
Format Model:
IMKERNEL
Description up to 512 characters
