The the values in the example above refer to A4 format: 210 x 297 mm = 595 x 842 points; US "letter" paper would give 8.5" x 11" = 612 x 792 points. Clearly a smaller bounding box would select only a subset of the image. For more information on encapsulated postscript see the "PostScript Language Reference Manual, 2nd edition" by Adobe Systems Incorporated. (Published by Addison Wesley, ISBN 0-201-18127-4) 7.3.5 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 D3PLOT via preferences in the .oa_pref file: see Appendix II Next section Page 7.19
