This chapter is really for the more experienced coder who wants more from Extractor.
The first option is to save a data file containing the offsets to the sprite data for each sprite. This option uses a standard saving system from this part of the menu structure:
Save ⇨ Offset List ⇨ {save box}.
The second option is to make the actual extracted data file provide more information, i.e. to create a data format which is more complex than just pure sprite data but still more manageable than the Acorn format. This is done using this part of the menu structure:
Save ⇨ Extracted ⇨ Set Format ⇨ {format window}
(The options are set on and off by clicking on the boxes down then left hand side, by the various options).
The first three options define the data to be at the start of the file (the file header). The sections of information will appear in the file header in the same order as they appear in the window.
The fourth and fifth option but the data they describe before each sprite/section in the screen data file. As before they appear in the order in which they are shown in the window.
The last option effects the way that the horizontal width is stored (from the third and fifth options) for mode 9 or 12 sprites. It stores the width of the sprite/section in numbers of bytes across instead of numbers of pixels.
All values are stored in words (4 bytes).
As this option is for the more experienced user an example has not been included, but it is not a particularly difficult part of Extractor to grasp.
