31.7.1 Compressing an Image File
You can compress an uncompressed image (including images created by previous versions of
ZENworks) by 40 to 60 percent of the original file size.
You can compress an image in two ways:
"Compressing an Opened Image File" on page 470
"Compressing an Unopened Image File" on page 471
Compressing an Opened Image File
Use this dialog box to set compression options so that it takes less time to restore the image file or
less space to store the file on your Imaging server.
IMPORTANT: If you have used Delete to hide files in the image, they are removed from the image
during compression.
To compress the image file:
1 Click File > Open.
2 Browse for and select the image file.
Large image files might take a few moments to open.
3 Click File > Compress Image.
4 Fill in the fields:
Image File to Compress: Specifies the name of the existing imaging file to compress.
Save Compressed Image As: Click the browse button next to this field to specify the location
and filename under which to save the image.
Compression Level: Specify an image-compression level:
Compress for Speed: Takes the least amount of time to compress but creates the largest
compressed image file.
Balanced Compression: Represents a compromise between compression time and image
file size. This option is used by default when an image is created.
Compress for Size: Creates the smallest image file but takes longer to compress.
5 Click Compress to compress the image file, using the settings you specified.
