PRIMER 22.1

Notes on Laser Plotting

Users on 3D devices should note that turning the laser on will temporarily force the graphics mode back to 2D. This is because a laser plot is intrinsically a 2D image and is computed in software.
Transient graphics added "dynamically" to the screen are never copied to laser files. Examples are cursor-pick symbols, and also the information added interactively with the DYNAMIC_LABEL function.
If an attempt to open a laser file fails because the file/directory refuses "write" permission, or the disk is full, you are warned and laser output is switched off.
You can switch laser output off and on at will in the course of assembling a file with multiple images. Sub-images will only be written when the laser is on.
Some of the defaults here may be preset outside PRIMER via preferences in the .oa_pref file: see Appendix M .
