Saving a Displayed Image

Saving to a File

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.

Saving to a SAS Data Set

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.
