Stiskanje

  Ta možnost omogoča določitev algoritma za stiskanje slike.

  Brez

    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].

  Pack Bits

    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.

    | Opomba
    These two compression modes can only be selected, if the image is in indexed mode and reduced to two colors. Use Image → Mode → Indexed to convert the image to indexed mode. Make sure that “Use black and white (1-bit) palette” is checked.

Save layers

  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.

  | Opomba
  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.

Crop layers

  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.

Shrani barvne vrednosti iz prosojnih slikovnih točk

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

Export as 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.

Metadata (edit)

  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.

Save Exif data

  When this option is enabled, EXIF metadata will be saved in the exported image.

Save IPTC data

  When this option is enabled, IPTC metadata will be saved in the exported image.

Shrani podatke XMP

  When this option is enabled, XMP metadata will be saved in the exported image.

Save color profile

  When this option is enabled, the color profile will be saved in the exported image.

Save thumbnail

  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.

Save GeoTIFF data

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

Save comment

  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.
