- FEATURES
- --------
-
- - All known formats of IFF pictures (including Overscan, HAM, Halfbrite,
- S-HAM) are supported. If a picture is larger than the screen, you may use
- the mouse to scroll around (If you have enough CHIP memory...)
-
- - Runs from both Workbench and CLI, creates an AppIcon under Kickstart 2.x
-
- - Uses double-buffering for best results if enough CHIP RAM is available
-
- - Can be used for demonstrations and slide-shows, see below
-
- - Powerful command option, for copying, deleting or archiving pictures
-
-
-
- REQUIREMENTS
- ------------
-
- ShowIFF requires the arp.library and, of course, the iff.library. These
- two files should be located in the LIBS: directory.
-
-
-
- WORKBENCH USAGE
- ---------------
-
-
- Under Kickstart 1.3:
-
- Select all pictures you wish to view while pressing the SHIFT key, then
- double-click the ShowIFF icon.
-
- You can also set the picture's default tool to 'ShowIFF' using WorkBench's
- 'Info' feature.
- If you wish to display all the pictures in a drawer, select the drawer, and
- while depressing the SHIFT key, double-click the ShowIFF icon. This works
- even with disk icons!
- If a drawer or disk contains another drawer, the pictures in that drawer
- will also be displayed.
-
-
- Under Kickstart 2.x:
-
- Under Kickstart 2.x you have an additional possibility, which you may
- prefer once you are familiar with Kickstart 2.x: You can put ShowIFF in
- your WBStartup drawer. When you boot your Amiga, ShowIFF is automatically
- started and creates an "AppIcon". This icon looks like any other icon, and
- you can freely chose it's name and it's position (see below). But this
- icon has an interesting feature: You can view a picture by simply dragging
- the icon of that picture on ShowIFF's AppIcon. This works for drawers and
- disks too, of course.
- If you wish to remove the ShowIFF AppIcon, simply start ShowIFF again.
-
-
- Tool Types:
-
- ShowIFF understands several tool types. You can edit them using the
- "Show Information" or "Info" commands from the Workbench menu. Here's
- a list of the recognized tool types:
-
- ICONXPOS Specifies the x coordinate of ShowIFF's AppIcon. This works
- only under Kickstart 2.x and above.
- Example: ICONXPOS=620
-
- ICONYPOS Specifies the y coordinate of ShowIFF's AppIcon. This works
- only under Kickstart 2.x and above.
- Example: ICONYPOS=120
-
- ICONNAME Specifies the name of ShowIFF's AppIcon (Only Kickstart 2.x).
- Example: ICONNAME=IFF Viewer
-
- OPTIONS Here you can specify several options, in the same format as
- if you would enter them from CLI. Works under 1.3 too.
- Example: OPTIONS=ALL DELAY 5 NOOVERSCAN LOOP
-
-
-
- CLI USAGE
- ---------
-
-
- The template is:
-
- Patterns/...,ALL/s,L=LOOP/s,D=DELAY/k,NB=NOBREAK/s,NO=NOOVERSCAN/s,COMMAND/k
-
- ShowIFF [files or patterns] [ALL] [LOOP] [DELAY delay] [NOBREAK]
- [NOOVERSCAN] [COMMAND "Command %s args"]
-
-
- Example: ShowIFF Lo-Res/Pic* Hi-Res/foo RAM:#? ALL DELAY 7
-
-
- files can be any number of file names, directories or disk names.
- All of the ARP wildcards can be used. (?,*,#?,...)
-
- ALL if this keyword is specified, pictures in sub-directories
- will also be displayed.
-
- LOOP if specified, repeatedly displays the pictures, which is
- useful for creating slide-shows or presentations.
-
- DELAY seconds specifies the delay between two pictures in seconds. If not
- specified, the delay is infinity. Note that you can always go
- to the next picture by pressing the left mouse button.
-
- NOBREAK disables the breaking features described below. Together with
- the LOOP keyword, a neverending and un-stoppable slideshow
- can be created.
-
- NOOVERSCAN display all pictures in the size of the Workbench screen, and
- never in overscan. This is useful if you want to see every
- pixel of a picture. NOOVERSCAN is automatically activated if
- the picture is too large to fit on an overscan screen. In
- this case you can use the mouse to scroll around.
-
- COMMAND cmd %s command to execute whenever the user presses the 'C' key
- while the picture is displayed. Examples:
-
- - You have a large collection of pictures and want to copy the
- best of them to to another disk. To do this, type
-
- ShowIFF * ALL COMMAND "Copy %s to DF1:"
-
- and hit the 'C' key on every picture you want to copy.
-
- - You want to delete the pictures you don't like. Type
-
- ShowIFF * COMMAND "Delete %s" ALL
-
- and hit 'C' on each picture you want to delete.
-
- The special parameter "%s" is automatically converted to the
- actual file name.
-
-
-
- KEYS AND MOUSE-BUTTONS
- ----------------------
-
- While a picture is displayed, you can press the following keys:
-
-
- LEFT MOUSE BUTTON
-
- Display the next picture. If there are no more pictures to show, ShowIFF
- closes its window and terminates.
- If in AppIcon mode, ShowIFF closes its window and waits for new pictures.
-
-
- RIGHT MOUSE BUTTON
-
- Abort immediately
-
-
- Ctrl-C (if the ShowIFF window or the CLI window is active)
-
- Abort immediately
-
-
- Ctrl-E (if the ShowIFF window or the CLI window is active)
-
- If you started ShowIFF from Workbench, ore enabled the "ALL" option from
- CLI, pressing Ctrl-E will skip all pictures in the current sub-directory,
- and return to the parent-directory (like in the CLI "Dir" command).
-
-
- 'C' key
-
- If you specified a command using the COMMAND keyword, this command is
- executed. If no command was given, nothing happens.
-
-
- MOVE THE MOUSE
-
- If the actual picture is larger than the screen, the visible portion will
- scroll according to your mouse movement.
-
- Note: HAM pictures may have color distortions on the left side. This is
- a hardware limitation of the HAM mode, and not a bug in ShowIFF.
