README.md

Preview

These files are a special class of Desk Accessory which reside in the PREVIEW subdirectory relative to DESKTOP2 (next to DESK.ACC). These DAs will be invoked automatically for certain file types when File > Open is run or the files are double-clicked.

show.text.file
- Handles text files (TXT $04)
show.image.file
- Handles image files (FOT $08)
- 8k Hires or 16k Double Hires images are supported
show.font.file
- Handles MGTK font files (FNT $07)

The files can optionally be copied into the DESK.ACC directory to allow direct invocation from the Apple menu. This can be useful to preview files of different file types e.g. image files saved as BIN $06.

See API.md for programming details.

See the DA README.md for build and installation details.

NOTE: ProDOS file type FNT $07 is reserved for Apple /// SOS font files, but given their scarcity the type is re-used here.
