``Save'' - write a volume to disk

VFX name:

save.

IMPROMPTU name:

Save.

purpose:

Save a volume to disk as an ANALYZE-format volume(.img) or compresses a volume using the Run Length Encoding technique (.rle).

input:

Volume in IMPROMPTU memory.

output:

Volume is written to specified file (compressed or not).

parameters:

Default parameters menu is

compress_image? = N or Y

This function saves the specified volume to disk as an ANALYZE-format volume by creating an ``img'' file to hold the data and a ``hdr'' file to store the header information. If the compress option is set to ``Y'' then compresses and saves the specified volume to disk by creating an ``compression.rle'' file to hold the compressed data and an ``compression.hdr'' file to store the header information of the UNCOMPRESSED image.

comments:

The Run Length Encoding technique is very image-dependent, and it works better with segmented images. It can be the case where the compressed image is biger than the original image if this one is a very detailed one.
