Tag Image File Format (TIFF)

TIF is one of most popular graphics file formats. It is used in lots of applications for different purposes. The following parameters are used to adjust settings of this format:

bpp

Bpp parameter specifies the number of bits used to transfer the color of one pixel. Its allowed values are:

The default value is: 32.

Example:

-convertto tiff bpp:48

compression

Compression specifies compression algorithm for resulting files. Its allowed values are:

The default value is: LZW.

Example:

-convertto tiff compression:JPEG

jpeg_quality

Jpeg_quality parameter specifies image quality. The higher is its value, the better is image quality. It can accept whole numbers from 25 to 100. The default value is: 85.

Example:

-convertto tiff jpeg_quality:73

jpeg_sample

Jpeg_sample parameter specifies channels of image compression. Today most JPEG files have YcbCr format (where Y-channel stands for brightness while Cb and Cr channels stand for color). Human eye is built in such a way that it perceives brightness change of neighboring pixels first and color change next. If we write an average true color image of photo quality into JPEG format, we can skip every second horizontal value of color channels and still have an image of nearly same quality. Each two pixels of the saved image will have two values of Y channel and one value of Cb and Cr channels. In Image Converter Command Line, this write mode is specified with “sample 4:2:2” parameter. Jpeg_sample parameter can accept the following values:

The default value is: 111.

Example:

-convertto tiff jpeg_sample:422

compression_level

Compression_level parameter specifies compression level for resulting files. Its allowed values arewhole numbers from 0 to 9. the lower is the value of compression_level, the better is image quality and the larger is file size.

Example:

-convertto tiff compression_level:3

multipage

Multipage parameter specifies whether resulting files should be saved as separate files or as one multipage file. Its allowed values are:

The default value is: as_is.

Example:

-convertto tiff multipage:separate_pages

quant

Quant parameter reduces the number of distinct colors used in an image while preserving visual image quality. Allowed values of quant parameters are whole numbers from 0 to 8.

The default value is: 8.

Example:

-convertto tiff quant:4

dither

Dither is a form of noise, or 'erroneous' signal or data which is added to sample data to minimize quantization error. Allowed values of dither parameter are: yes and no.

The default value is: yes.

Example:

-convertto tiff dither:no

byte_order

Byte_order parameter specifies byte order in the resulting file. It can accept two values: little_endian � big_endian.

The default value is: little_endian.

Example:

-convertto tiff byte_order:big_endian

thumbnail

Thumbnail parameter specifies whether thumbnails should be created for converted images. Thumbnails are used to preview images in browsers and graphics viewers. Its allowed values are: yes and no.

The default value is: No.

Example:

-convertto tiff thumbnail:Yes

strip

Strip parameter specifies whether the file should be split into stripes. Its allowed values are:

The default value is: Multistrip.

Example:

-convertto tiff strip:Singlestrip

exif

Exif parameter specifies whether EXIF (information on shooting parameters of the camera used) will be saved in resulting files. Its allowed values are:

The default value is: No

Example:

-convertto tiff exif:Yes

iptc

Iptc parameter specifies whether IPTC (metadata - name, copyright, category) will be saved in resulting files. Its allowed values are:

The default value is: No.

Example:

-convertto tiff iptc:Yes

general example

ICPCL.exe -convertto tiff bpp:48 compression:JPEG jpeg_quality:60 jpeg_sample:422 compression_level:3 multipage:separate_pages byte_order:big_endian thumbnail:Yes strip:Singlestrip exif:Yes iptc:Yes quant:4 dither:no -source "C:\Original files" -dest "C:\Converted files"

tips

  1. Jpeg_quality and jpeg_sample parameters should only be used with JPEG, JBIG and JPEG 6+ compression algorithms.

    Example:

    ICPCL.exe -convertto tiff bpp:48 compression:JPEG jpeg_quality:60 jpeg_sample:422 -source "C:\Original files" -dest "C:\Converted files"
  2. Compression_level parameter should only be used with FLATE compression algorithm.

    Example:

    ICPCL.exe -convertto tiff bpp:48 compression:FLATE compression_level:3 -source "C:\Original files" -dest "C:\Converted files"
  3. EXIF information is saved in resulting files only if it exists in source files.

  4. IPTC data are saved in resulting files only if they exist in source files.

  5. When creating multipage files, the order of their pages is specified by the order of source file conversion (sorting specified with the help of -sort key).
