SAS/SPECTRAVIEW
allows you to save a displayed image to either a TIFF (Tagged Image File Format)
file or a PostScript file, for example, to use in presentations. To save an
image:
- Use a visualization technique to display an image,
and include customizations if desired.
- Select the [Save] global button.
- Specify the file format by
selecting either [PostScript file] or [TIFF file]. Note that TIFF
files can be used as input to other SAS procedures and products.
- Use the left mouse button and click the display
window you want to save. A message in the text window asks you to enter a
filename, and the cursor changes to the input cursor.
- In the text window, enter a one- or two-level
filename for the file. Pressing Enter without specifying a filename
cancels the save request.
You can save current data values to a new SAS data set.
Then, for example, you can use the new data set with other SAS System products.
The values that are saved depend on what is displayed, which in essence is
visual subsetting. That is, the data saved depends on what visualization technique(s)
are currently active and how they are displayed:
- If a cutting plane is displayed, only the data
points on that cutting plane are saved.
- If a point cloud is displayed, only the data points
in the point cloud are saved.
- If two or more images are displayed, then the
intersection of those images are saved. For example, if two cutting planes
are displayed, then only the data points along the intersection of the two
planes are saved. Likewise, if both a cutting plane and a point cloud are
displayed, only the data points on the cutting plane and in the point cloud
are saved.
- If no image is displayed or if all the data is
displayed, then all values are saved. In addition, if you loaded a SAS data
set for which you specified a WHERE clause to load a subset, you can save
the subset of data as a new data set.
Note that missing values are saved, unless the image
is a point cloud, then missing values are not saved.
To save data values:
- Use a visualization technique to
display an image,
and include customizations if desired.
- Select the [Save] global button.
- Select [SAS data
set]. A message
in the text window asks you to enter a filename, and the cursor changes to
the input cursor.
- In the text window, enter a one- or two-level
filename for the SAS data set. Pressing Enter without specifying a filename
cancels the save request.
