For a graphical display of these attributes see the end of this supplement The Seed Point When dropped a seed point will fill up to either the boundary of the page or a solid line Use this facility with caution as an error may have strange results For example dropping a seed point inside a rectangle with a dotted boundary will cause the entire page to be filled OZPRINT The print utility OZPRINT 13 in reality driver programme that uses the FIG drawing system to draw the user s figures OZPRINT parses the parameters and then calls FIG and spawns it into the background A source of error is calling OZPRINT twice or more in rapid succession This error is caused by FIG using a scratch file to store some intermediate data When more than one OZPRINT is executing at one time collisions over this scratch file may occur thus leading to errors Therefore to avoid this error allow several minutes between calls to OZPRINT This should not be too inconvenient as OZPRINT allows more than one file to be printed at a time Refer to the OZDRAW Users manual for further discussion Drawing a Filled Figure When drawing a filled figure there are two considerations to be taken into account 1 OZPRINT cannot print a filled concave figure due to the fill algorithm it uses Unpredictable results may occur if this is done 2 Printing a figure that is filled with a dotted boundary will cause more than that figure to be g g filled The a

AW stores the user produced figures in a file that uses ASCII characters The actual file format is readily understandable by inspection of any OZDRAW file so no further description will be given here Using an ASCII file format gives the following advantages 1 the OZDRAW file can be edited by the user using any suitable text editor this approach is certainly only recommended for the experienced user as errors can produce unpredictable results 2 transferring binary files between systems such as between the IRIS and VAX 11 780 can be messy if systems use different sized data types and 3 the ASCII format lends itself to other programmes producing complex figures for use with OZDRAW that would normally be impractical to draw with OZDRAW EXAMPLES OF FIGURES PRODUCED USING OZDRAW The next four pages are included to show to the new user what OZDRAW is capable of These figures were produced by students other than the author for their academic theses 16 Fig 1 1 Two contours on adjacent parallel planes Qj surface patch defined by Qj Qk Pk Example 1 bounding box for 1 1 Fig 3 10 Vector radiating from center coordinate through the interior coordinate towards the outer contour for tentative mapping inner outer distance coord coord large relative change in distance and mapped coordinate number sequencing Example 2 Set 7717 au H SR E 111 HET
