- Programme: SLIDE.EXE; QSLIDE.EXE
- Author: TapirSoft Gisbert W.Selke, 11 Jan 1989
- Additions: Stefan Kaufmann, 24 Nov 1988
- Language: TurboPascal 5.0, under MS-DOS 3.3.
- Usage: slide <filename> [options]
-
- These programmes are copyrighted but may be distributed and used for free.
-
- Display pictures stored in <filename> as stored by, e.g.,
- MapView 2.0. The first time through, it will try to read
- the whole file into memory and later display from there;
- however, if there are too many pictures (depending on your
- PC's available memory and the pictures' size), they will be
- read from disk. Pressing any key quits the programmes;
- however, cf. the /K option below.
-
- SLIDE does clean screen swapping at all stages; QSLIDE,
- is less smooth while reading from disk, but is about
- 5 times as fast when displaying from memory. Also, QSLIDE
- will work only on CGA and Hercules adapters, due to 80x86
- segment sizes.
-
- The programmes check whether the slides in the file were
- produced on the same kind of display adapter.
-
- Default file extension is '.PIC'.
-
- Options are: /R<repeatcount> /D<delay> /K
-
- where <delay> is a delay in milliseconds between each two
- slides, and the whole series is repeated <repeatcount> times.
- If /K is specified, pressing Q, ESC or Ctrl-C only will
- abort the programmes; any other key will immediately switch
- to the next picture. This is useful for occasional
- shortening of large delay times.
- Defaults are no delay and one repetition; maxima are
- /D65535 and /R65535. In the special case of <delay>=0, the
- delay time is set to 655350 milliseconds; if <repeatcount>=0,
- the series is repeated indefinitely, or until a key is
- pressed.
-
- There is a hard limit on the maximum number of screens that
- can be stored in memory; it is currently set at 75. More
- pictures can be displayed, but will have to be read from disk.
-
- SLIDE and QSLIDE need the appropriate Borland graphics
- driver (BGI) for operation.
