Classic.tif

+

+ Classic.tif is a basic Classic TIFF file. All files in this package have the same actual image content, + so this TIFF file serves as a reference. +

+

+ Format: Classic TIFF
+ Byte Order: Intel
+ Ifd Offset: 12302
+     ImageWidth (1 Short): 64
+     ImageLength (1 Short): 64
+     BitsPerSample (3 Short): 8, 8, 8
+     PhotometricInterpretation (1 Short): RGB
+     StripOffsets (1 Short): 8
+     SamplesPerPixel (1 Short): 3
+     RowsPerStrip (1 Short): 64
+     StripByteCounts (1 Short): 12288
+

+

BigTIFF.tif

+

+ BigTIFF.tif ressembles Classic.tif as close as possible. Except that it's a BigTIFF, that is... +

+

+ Format: BigTIFF
+ Byte Order: Intel
+ Ifd Offset: 12304
+     ImageWidth (1 Short): 64
+     ImageLength (1 Short): 64
+     BitsPerSample (3 Short): 8, 8, 8

+     StripOffsets (1 Short): 16
+     SamplesPerPixel (1 Short): 3
+     RowsPerStrip (1 Short): 64
+     StripByteCounts (1 Short): 12288
+

+

BigTIFFMotorola.tif

+

+ BigTIFFMotorola.tif reverses the byte order. +

+

+ Format: BigTIFF
+ Byte Order: Motorola
+ Ifd Offset: 12304
+     ImageWidth (1 Short): 64
+     ImageLength (1 Short): 64

+     RowsPerStrip (1 Short): 64
+     StripByteCounts (1 Short): 12288
+

+

BigTIFFLong.tif

+

+ All previous TIFFs specify DataType Short for StripOffsets and StripByteCounts tags. This BigTIFF instead specifies DataType Long, for these tags. +

+

+ Format: BigTIFF
+ Byte Order: Intel
+ Ifd Offset: 12304
+     ImageWidth (1 Short): 64
+     ImageLength (1 Short): 64

+     RowsPerStrip (1 Short): 64
+     StripByteCounts (1 Long): 12288

+

BigTIFFLong8.tif

+

+ This next one specifies DataType Long8, for StripOffsets and StripByteCounts tags. +

+

+ Format: BigTIFF
+ Byte Order: Intel
+ Ifd Offset: 12304
+     ImageWidth (1 Short): 64
+     ImageLength (1 Short): 64

+     StripByteCounts (1 Long8): 12288
+

+

BigTIFFMotorolaLongStrips.tif

+

+ This BigTIFF has Motorola byte order, plus, it's divided over two strips. StripOffsets and StripByteCounts tags have DataType Long, so their actual value fits inside the IFD. +

+

+ Format: BigTIFF
+ Byte Order: Motorola
+ Ifd Offset: 12304

+

BigTIFFLong8Tiles.tif

+

+ BigTIFFLong8Tiles.tif is a tiled BigTIFF. TileOffsets and TileByteCounts tags specify DataType Long8. +

+

+ Format: BigTIFF
+ Byte Order: Intel

BigTIFFSubIFD4.tif

+

+ This BigTIFF contains two pages, the second page showing almost the same image content as the first, except that the black square is white, and text color is black. + Both pages point to a downsample SubIFD, using SubIFDs DataType TIFF_IFD. +

Classic.tif

-

- Classic.tif is a basic Classic TIFF file. All files in this package have the same actual image content, - so this TIFF file serves as a reference. -

BigTIFFLong.tif

-

- All previous TIFFs specify DataType Short for StripOffsets and StripByteCounts tags. This BigTIFF instead specifies DataType Long, for these tags. -

BigTIFFMotorolaLongStrips.tif

-

- This BigTIFF has Motorola byte order, plus, it's divided over two strips. StripOffsets and StripByteCounts tags have DataType Long, so their actual value fits inside the IFD. -

BigTIFFSubIFD4.tif
