- If you a load and view a GIF image on the Workbench screen with the
- V42 "picture.datatype" this happens:
-
- 1.) "gif.datatype" loads chunky image.
-
- 2.) "gif.datatype" converts it to planar format.
-
- 3.) "picture.datatype" converts image to chunky format to be able to
- apply color mapping.
-
- 4.) "picture.datatype" applies color mapping.
-
- 5.) "picture.datatype" converts image to planar format to be able to
- display it.

- With V43 this happens:
-
- 1.) "gif.datatype" loads chunky image.
-
- 2.) "picture.datatype" applies color mapping.
-
- 3.) "picture.datatype" converts image to planar format to be able to
- display it.

- [Both benchmarks on an A4000/040 without using a graphics board.]
