- #15: InstallFont and Big Fonts
-
- Revised by: Eric Soldan & Matt Deatherage July 1989
- Written by: Guillermo Ortiz June 1987
-
- When the Font Manager executes InstallFont, it may try to scale the selected
- font if bit 15 of the ScaleWord is clear; a font larger than 32K causes this
- call to fail.
- Changes since November 1988: Noted System Software 5.0 enhancements.
- _____________________________________________________________________________
-
- The Font Manager cannot scale a font which is larger than 32K, so InstallFont
- will fail if scaling is required and the desired font exceeds this limit. If
- the call fails for this reason, it will report an FMScaleSizeErr ($1B0C)
- error.
-
- This is not the same situation as when there is not enough memory available to
- hold a newly scaled font. The situation will generate Memory Manager errors.
-
- System Software 5.0 can scale fonts to be larger than 32K, so there is no
- longer the limit imposed by System Disk 4.0 and earlier. In addition, System
- Software 5.0 can handle font sizes up to 255 points, if memory is available.
- Note that this is a different situation than trying to scale a font which was
- originally larger than 32K, but both work under 5.0.
