Manipulating font records using OpenScrape

Figure 4.6‑18 OpenScrape Create Font button

The “Create Font” button on the Table Map Editor window is used to create new font records. This button is only available if a Text transform is specified for the selected region record.

To create new font records:

1. Select a Region record that has a text transform

2. Ensure that the Region’s color parameters provide good separation of foreground and background pixels (preview in the Pixel Separation field)

3. Click the “Create Font” button

Note: The number of the text transform in the region (Text0, Text1, Text2, or Text3) determines which Font record group (0 to 3) the new fonts will be added to.

Assuming that some of the pixels in the selected region represent unknown font characters, then the following window will appear when the “Create Font” button is clicked:

On this window, a list of the individual font characters that OpenScrape thinks it has found is displayed in the list on the left side. As we have not told OpenScrape what character each of these pixel groups represent, they are displayed as question marks. (Note that the question mark can be considered a valid font character as well, so if you use this character in your Table Map, be aware of this fact).

For each unknown character in the list on the left, click to select it, then either:

§ Enter which character is represents in the “Character” field (in this example, it is evident that the grouping of foreground pixels represents the capital letter P), or

§ Click on the “Delete” button if this is not a character you want stored in the Table Map for some reason, such as it is a duplicate, or the automatic character separation didn’t work quite correctly

Clicking on the “Sort” button will arrange the characters alphabetically in the list, which might make them easier to process.

When you dismiss this window by clicking on the “OK” button, OpenScrape will add each of the characters in the list on the left, their ASCII representation, and their pixel layout to the list of Table Map records. This includes duplicates, and unknowns (question marks), so be sure to remove these prior to clicking “OK”, or your Table Map might get filled with superfluous Font records.
