- DrawShape
- ¯¯¯¯¯¯¯¯¯
- by D. Salt
-
- Version 1.06 (15 Jun 1995)
-
- Takes path objects from Draw and moulds them to fit between two other paths.

- How to use
- ¯¯¯¯¯¯¯¯¯¯
- When DrawShape is loaded, it puts two icons on the iconbar. Both appear as
- raised slabs.
- The left-hand slab has on it two cyan lines, one above the other. This is
- the mould icon.
- The right-hand slab has on it a pair of compasses. This is the image icon.
- It initially appears greyed out because DrawShape has no mould to use.
-
- 1. Select the two paths you wish to use as the template.
-
- 2. Export them to DrawShape (use 'Save selected'), dropping them on the
- mould icon.
-
- 3. Select the paths (or path groups) you wish to mould.
-
- 4. Export them to DrawShape (save selected), dropping them on the image
- icon. Or export the whole file if you want to process the whole file.
-
- 5. DrawImage will process the file, and exports the resulting file to Draw.
- This can now be combined with the original drawing.
-
- The two paths describe the upper and lower bounds of the moulded image.
- Whichever is used as the lower bound must be 'in front of' the other path.
- It is important that the paths used in the mould:
- - are individual path objects;
- - do not contain moves; and
- - are not grouped together.
- If the paths are rejected by DrawShape, you will be told why, and the
- previous mould (if there was one) will be retained.
-
- There is a maximum line segment length. This is currently defined the length
- of the bounding box diagonal divided by the number of line/curve segments in
- the upper part of the mould then by the number in the lower part. It is
- limited to the range 0.1pt to 7.2pt (0.1in).
-
-
- The main menu contains:
- - Info
- - Fast
- This controls whether the screen is blanked while moulding. When on,
- this option reduces the time taken by around 12%.
- - Shortcut
- This controls which of two line length calculation methods is used - the
- slower one is much more accurate, but the faster method appears to have
- little effect on the output quality. Using the faster method reduces
- the time taken by around 45%.
- With both options on, the time taken is around 49% of the time that
- would otherwise be taken.
- - Clear
- This causes DrawShape to forget about the current mould definition.
- - Quit

- "Round the Bend" (AU December 1992).
