- Virtual Art Gallery 1.0
- Copyright Jason Harper 1993 All rights reserved.
-
- DESCRIPTION:
- A walkthru of your own personal art gallery, with any standard IIgs pictures
- you have displayed as if hanging on the walls, in true 3D perspective.
-
- USAGE:
- After a short delay during which the program precalculates some of the math
- results it will need later, you will get a standard file selection dialog which
- you use to locate a folder containing any IIgs graphics files you have. The
- exact file that you select is irrelevant: the program loads all pictures from
- the same folder in the order that it finds them, until memory is full. Once
- the display starts, you can add and remove pictures using the controls at the
- bottom of the screen. As usual, you exit the program by selecting Quit from
- the File menu, or typing Apple-Q.
-
- SYSTEM REQUIREMENTS:
- Apple IIgs
- System software 5.0 or higher
- About 1MB RAM (minimum RAM requirements not tested)
-
- SYSTEM RECOMMENDATIONS:
- Accellerator card (a 7 MHz/8k cache TransWarp more than doubles the speed)
- 2MB+ RAM (each additional meg allows 32 more pictures)
-
- FILE COMPATIBILITY:
- Loads the following standard IIgs graphics file types:
- Type $C1, auxtype 0: uncompressed screen images (all)
- Type $C0, auxtype 0: Paintworks 320 mode images (top half only)
- Type $C0, auxtype 1: PackBytes/Eagle format (all)
- Type $C0, auxtype 2: Apple Preferred format (must be one screen wide,
- and at least one screen high: loads top screen only)
- All loaded pictures are converted to grayscale, since arbitrary color
- palettes can't be displayed side-by-side on the screen.
-
- CONTROLS:
- Pause, Speed: these should be obvious.
- Remove this picture: available after selecting a picture by clicking on it
- (this is easier when paused). Removes the picture from the display.
- Show more pictures: available if there wasn't enough memory to hold all
- pictures in the folder you selected. Removes pictures (no choice over which
- ones) and replaces them with additional pictures from disk.
- New picture set...: removes all pictures and allows you to select a folder from which to load new pictures.
- Add pictures to set...: available if there is at least 100K of free memory.
- Allows you to select a folder from which to load additional pictures.
- Close all NDAs, under the Apple menu: since the display can't be generated
- while there are any desk accessories open that might obscure it, this option
- is available for you to quickly get any open accessories out of the way.
-
- DISTRIBUTION:
- You may redistribute this program under the following conditions: all three
- files (program, background image, and this text file) must be present in their
- original, unaltered condition, and there must be no charge for it other than
- reasonable media or connect time costs.

- I am particularly interested in hearing any suggestions you may have on future
- uses of this display technology. Note that programs using this technology
- will not necessarily require an accellerator card: by reducing the area of the
- display (down to 25% of the screen, perhaps), the speed can be made reasonable
- even on an unenhanced IIgs.
