Стиснення

За допомогою цього пункту ви можете вказати алгоритм, який буде використано для стискання зображення.

Немає

No compression is used. This is fast, and lossless, but the resulting file can be very large.

LZW

The image is compressed using the «Lempel-Ziv-Welch» algorithm, a lossless compression technique. This is efficient and fast. More information at [WKPD-LZW].

Упаковані біти

This is a fast, simple compression scheme for run-length encoding of data. Apple introduced the PackBits format with the release of MacPaint on the Macintosh computer.

A PackBits data stream consists of packets of one byte of header followed by data. (Source: [WKPD-PACKBITS])

Deflate

This is a lossless data compression algorithm that uses a combination of the LZ77 algorithm and Huffman coding. It is also used in Zip and Gzip files and PNG images. Source: [WKPD-DEFLATE].

JPEG

This is a very good compression algorithm but lossy. This is the same compression as used in JPEG images. Since it is lossy, you should not use this when image quality is important. This compression can not be used when your image is in indexed mode.

CCITT Group 3 fax, CCITT Group 4 fax

These are black and white formats developed to transfer images by FAX.

[Примітка] Примітка

These two compression modes can only be selected, if the image is in indexed mode and reduced to two colors. Use ImageModeIndexed to convert the image to indexed mode. Make sure that «Use black and white (1-bit) palette» is checked.

Зберегти шари

When enabled, each layer will be stored as a separate page in the TIFF image, starting from the bottom. When disabled, only the merged result will be stored.

[Примітка] Примітка

Not all image viewers support loading more than the first page of a TIFF image. Since the background layer is what we store first, it may be better to disable this setting if other programs you work with can't handle that.

Обрізати шари

When Save layers is checked, this option, which is enabled by default, will resize all layers to the size of the image. TIFF images can not have negative offsets. This option enables you to import the TIFF again without having to change the position of layers that had a different size as the image in the original.

Зберігати значення кольору прозорих точок

When this is enabled the color values are saved even if the pixels are completely transparent.

Експортувати як CMYK

If you have a CMYK profile assigned to your image as soft-proofing profile, this setting can be checked to have your image exported using that CMYK profile. This is sometimes required when you have your image professionally printed. Your printing company will tell you if this is needed.

If this setting is disabled, you don't have a soft-proofing profile set for this image yet. See assigning a Soft-Proof Profile.

The name of the CMYK profile that is assigned to this image will be shown below this setting.

Редактор метаданих

You can click the «(edit)» link to open the metadata editor to change or add any metadata that you want to be included in the image. Note: you will also still need to enable the relevant metadata saving options listed below.

The metadata settings in the export dialog override the default values set in your Metadata Export Preferences.

Зберегти дані Exif

Якщо позначено цей пункт, до експортованого зображення буде збережено метадані EXIF.

Зберегти дані IPTC

Якщо позначено цей пункт, до експортованого зображення буде збережено метадані IPIC.

Зберегти дані XMP

Якщо позначено цей пункт, до експортованого зображення буде збережено метадані XMP.

Зберегти колірний профіль

Якщо позначено цей пункт, до експортованого зображення буде збережено профіль кольорів.

Зберегти мініатюру

When this option is enabled a thumbnail will be saved in the exported image as part of the EXIF metadata. This will also cause certain EXIF tags to be saved, even if you have disabled saving EXIF metadata.

Зберегти дані GeoTIFF

When this option is enabled GeoTIFF metadata that was present in the original image will be saved in the exported TIFF image.

Зберегти коментар

Here you can enable saving a comment that is associated with the image. The comment can be entered in the text box below this option.
