TIFF — Tagged Image File Format

TIFF — Tagged Image File Format

Banyak Image gambar yang dapat didukung dengan spesifikasi TIFF atau LibTIFF dapat dibaca oleh imread.

imread mendukung kemampuan TIFF berikut ini:
–  Setiap jumlah sampel-per-pixel

–  CCITT kelompok 3 dan 4 FAX, Packbits, JPEG, LZW, Deflate, kompresi ThunderScan, dan gambar tidak terkompresi.

–  Logis, grayscale, diindeks warna, truecolor dan gambar hyperspectral.

– RGB, CMYK, CIELAB, ICCLAB spasi warna.

If the color image uses the CMYK color space, A is an M-by-N-by-4 array. To determine which color space is used, use imfinfo to get information about the graphics file and look at the value of thePhotometricInterpretation field. If a file contains CIELAB color data, imread converts it to ICCLAB before bringing it into the MATLAB workspace because 8- or 16-bit TIFF CIELAB-encoded values use a mixture of signed and unsigned data types that cannot be represented as a single MATLAB array.

–  Data dikelompokan dalam tiles atau scanlines.

Berikut ini format-specific syntaxes untuk file TIFF.

A = imread(…) returns color data that uses the RGB, CIELAB, ICCLAB, or CMYK color spaces. If the color image uses the CMYK color space, A is an M-by-N-by-4 array.

[…] = imread(…, ‘Param1’, value1, ‘Param2’, value2, …) uses parameter/value pairs to control the read operation. The following table lists the parameters you can use.
Parameter    Value
‘Index’    Positive integer specifying which image to read. For example, if you specify the value 3, imread reads the third image in the file. If you omit this argument, imread reads the first image in the file.

Structure array returned by imfinfo.
