When processing large numbers of sprites, the manual system of creating extraction instruction (using "Add to List") and setting the sprite for them can be extremely slow and laborious. So, to avoid this there are two other methods other than the manual system. Semi-Automatic and Automatic. The part of the menu structure needed is this:
Extract ⇨ Manual ⇨ {et cetera}
Semi-Auto ⇨ {sprite list}
Automatic
Semi-Automatic
~~~~~~~~~~~~~~
This option replaces the two stages mentioned above ("Add to List" and select sprite) with a single mouse click. You use the sprite list shown above to select a sprite to be extracted from and Extractor creates a new extraction instruction from the previously selected one, set to extract the whole of the new sprite. Although the section boundaries may be different from the original extraction instruction, the mask definitions and the extraction style are the same. Therefore if your original sprite extraction uses a mask and the sprite you select from the menu has no mask then an error will occur and the new extraction instruction will not be created.
Automatic
~~~~~~~~~
Selecting this from the menu will make Extractor go through the process used in the Semi-Automatic system for each of the sprites in memory, in the order they appear in memory. Also as above, if the original extraction instruction requires a mask then an error will occur for each sprite in memory that has no mask. This process may take a short time to complete if you have a lot of sprites in memory.
An example is unsuitable for this chapter but I recommend that Extractor users get familiar with the time saving systems by experimenting. Little can go wrong and the time saving systems are quite handy.
