- Compresión
-
This option allows you to specify the algorithm used to compress the image.
- Ninguna
-
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.
![[Nota]](images/note.png)
Nota Estos dos modos de compresión sólo se pueden seleccionar, si la imagen está en modo indexado y reducida a dos colores. Use → → para convertir la imagen a modo indexado. Asegúrese de marcar “Usar paleta en blanco y negro (1-bit)”.
- 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.
Nota 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
-
Cuando se marca Guardar capas, esta opción, que está activada de manera predeterminada, cambiará el tamaño de todas las capas al tamaño de la imagen. Las imágenes TIFF no pueden tener desplazamientos negativos. Esta opción le permite importar el TIFF nuevamente sin tener que cambiar la posición de las capas que tenían un tamaño diferente al de la imagen original.
- Guardar los valores de color de los píxeles transparentes
-
Cuando esta opción está activada, los valores de color se guardan incluso si los píxeles son completamente transparentes.
- 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.
- Metadatos (editar)
-
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.
- Guardar los datos Exif
-
When this option is enabled, EXIF metadata will be saved in the exported image.
- Guardar los datos IPTC
-
When this option is enabled, IPTC metadata will be saved in the exported image.
- Guardar los datos 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.
- Guardar los datos GeoTIFF
-
Cuando esta opción está activada, los metadatos GeoTIFF que estaban presentes en la imagen original se guardarán en la imagen TIFF exportada.
- Save comment
-
Aquí puede activar guardar un comentario que está asociado con la imagen. El comentario se puede introducir en el cuadro de texto situado debajo de esta opción.
