- This propagation can be a real pain - hence the need for version control
- on software projects. This is directly related to genetic axioms where
- "traits" (bugs, incorrect versions, mistakes etc) get propagated.
-
- Last year I produced all the colour graphics for a multimedia point-of-sale
- machine using touch-screen technology for a large bank.
-
- There were 130 colour images with graphic text to produce, with some elements
- whittled down from 500 meg of scans...
-
- If one image was used as a parent of child images then any errors or
- modifications that needed doing had to be applied to the entire family.
- It became clear that tracking these traits would become a major nightmare,
- as they wouldn't be really evident until the images were running in sequence,
- or would only be discovered in the process of modifying something else...
-
- My solution was to build a massive "parts list", from which the images could
- be created from scratch on demand, with the use of macros on the rare
- occasions I needed to sleep!! After three months of designing creating
- editing and refining the images and working out just what the hell was going
- on (palettes), the images were assembled semi-automatically in a week or so
- for final delivery.
-
- Perhaps there's a paradigm here...
