7.2.2.3 Embedding bitmaps in a font
You can specify a font for which you want certain characters changed to in-line bitmaps in the WinHelp file. You embed bitmaps in the font as follows:
1. Choose a font to represent bitmaps.
2. Assign a different character in that font to each bitmap.
3. Place the assigned characters--in that font--in your FrameMaker document, wherever you want the bitmaps to appear in WinHelp.
In the configuration file you identify the font (BitmapFont=fontname), then map the characters. You can represent a character either as itself or as its decimal numeric value. For example:
; BitmapFont = name of font to check for chars to map here
; following chars are remapped when in BitmapFont in WinHelp only
; sample mappings are all to bitmaps supplied in Help Workshop
; * = bullet, using the decimal numeric value of the character
; A = arrow, using the character itself (printable, not ";" or "[")
Add a line for each character you want to map, such as:
to make all asterisks in that font turn into in-line calls for a bullet image. Any characters you do not map remain themselves. To use the semicolon ";" or the left bracket "[", you must precede the character with a backslash to avoid conflict with configuration-file conventions.
Make sure you tag only one character at a time with the bitmap font, and watch out for preceding or following spaces in the same font, which would disable the bitmap usage.
When you use actual letters as [BitmapChars] keys, they are case insensitive; "A" is mapped the same as "a". Using the decimal numeric value of a character as the key instead has two advantages:
• You can map high-bit-set characters, which are often used for symbols.
• You can assign different bitmaps to uppercase and lowercase characters.
