Type: Character

Details

WRITE writes the currently selected image to an external file. The file can be specified either directly (using its physical filename path) or by using the information that was returned by a previous LNAMEMK function call. The LNAMEMK function creates a character variable that contains information about the location of the image (even if it is to reside in a SAS catalog), as well as information about other image attributes.

The FORMAT= attribute (described in Attributes for Writing Image Files) must be specified if image-path does not include that information.

Examples

Write an image to a SAS catalog:

path=lnamemk
(5,'mine.images.sign','FORMAT=CAT');
rc=imgop(task-id,'WRITE',path);

Specify a file in the WRITE command. (Notice that file attributes are included.)

rc=imgop(task-id,'WRITE','/user/images/sign.tif',
   'FORMAT=TIFF COMPRESS=G3FAX');
