Display 39.11 (c) Copyright 1990-1999 Amiga, Inc. Display is a program for displaying IFF ILBM format image files. V39.x Display supports V39 and 8-bit-per-gun AA graphic modes, but still runs under 1.3 and 2.0 as long as iffparse.library is present. (2.04 Workbench's iffparse.library will run under 1.3.) The Display program can display single pictures, or can present a keyboard, mouse, or automatically advanced slide show. Display can also be used to print ILBM graphics. Under 2.0 and higher, Display supports overscan screens centered based on the user's Preferences, autoscroll screens, and explicit modeid for display if desired. Usage Summary ============= CLI Usage: Display [from filelist] OR file [file file...] [opt [mlbpaenvf][t=n][d=x]] opts: ouse (1 pic: mm) oop ack

CTRL/D to break a script Displaying a single ILBM file ============================= From CLI: Display filename [opt [mlbpaenvf][t=n][d=x]] (options explained later) From Workbench: either Use the left mouse button to click on (select) the Display icon, then shift/double-click the ILBM picture file icon. or single click the ILBM picture file icon then select the Workbench Icon menu "Information" item. Enter Display as the Default Tool in the Information requester and Save. Now double-clicking that ILBM picture icon will automatically load the Display program and display the picture. Closing the display: By default, clicking in the upper left corner or using CTRL-C will close the display. Other options described later allow mouse advance, looping, and automatically timed displays. Displaying multiple ILBM picture files as a "slide show" ======================================================== Display has the ability to do a slide show. There are several methods for doing a slide show. Some are more useful for on-the-fly situations, and others are more suitable for planned presentations. From CLI: (options explained later) either Display filename filename [filename [filename...]] [opt options] or Display from filelist [opt options] where filelist is a file which contains an ASCII text list of the ILBM filenames you want to display. A filelist file can be created with any plain ASCII text editor such as Ed or Memacs. The contents of an example filelist follows (assuming you have a directory called Pictures containing some ILBM graphic files): Work:Pictures/MonaLisa Work:Pictures/Max Work:Pictures/NewYork Certain per-picture options may also be specified on each line of a filelist (see Options section later). From Workbench: either Single-click on Display, then shift-click the pictures you wish to display, shift-double-clicking on the last picture. or Set up a slideshow file as follows: Create a text filelist as described above and place the file in a directory accessible from Workbench. Create a "Project" type icon for the file and save the Project icon in the same directory as your filelist file, giving it the same name as your filelist but with ".info" added to the name. Then select your Project icon (you may have to Update the window first) then select Information from the Workbench Icon menu. Enter Display as the Default Tool, and add the following tooltype: FILELIST=TRUE Also read about the additional Tooltype options below. You may wish to add some like MOUSE=TRUE (for a mouse-advanced show) or LOOP=TRUE and TIMER=seconds for an automatic show. Advancing the display: By default, you must click in the upper left corner or CTRL-C to advance from one displayed picture to the next. However, with simple options suchas MOUSE (m), LOOP (l), and TIMER (t), described in #3 below, you can advance and back up using the mouse, and create automatic looping timed displays. CTRL-D will terminate an entire slide show and exit Display. Options ======= From CLI, Display options are specified after the filename(s) by using the "opt" keyword followed by your options. Example: Display mypicture opt m In addition, certain options may be specified on a per-picture basis in a text filelist for Display. From Workbench, options are specified as ToolTypes in the icons of the Display program, or the ILBM file icons, or in the icon of a filelist. ToolTypes are entered using the "Information" selection in Workbench's "Icon" menu. (Single click an icon, then select the Workbench menu item). CLI Workbench Description === ========= =========== FROM filelist FILELIST=TRUE Display the pictures LISTED in the text filelist file attached to this icon (one picture and optional options listed per line) m MOUSE=TRUE Left mouse button advances slideshow, right goes backwards mm MMOUSE=TRUE Left mouse button advances slideshow, even if one one picture is being shown (i.e. click on picture and it goes away) l LOOP=TRUE Rather than exiting after the last picture, loop back to the first picture. b BACK=TRUE Causes pictures to remain as the back screen, unactivated. Useful when printing pictures while working. a AUTOSCROLL=TRUE If picture is bigger than visible display clip, enable autoscrolling - i.e. automatic scrolling when mouse reaches edge of visible display p PRINT=TRUE Cause Display to automatically print each picture that is displayed. Note that you can also print manually by pressing CTRL-P. e EHB=TRUE Treat unspecified (no CAMG) 6-bitplane pictures as Extra Halfbrite rather than HAM. n NOTRANSB=TRUE A 2.0 and ECS option. Causes borders to NOT be transparent when genlocked. v VIDEO=TRUE A 2.0 and ECS option. Causes picture to be displayed with full-video display clip. f BESTFIT=TRUE Ignore CAMG modeid if any and instead let OS decide best modeid to display in. s NOMONITOR Crudely strips monitor ID if any from CAMG r NOCENTER If picture is larger than Max Overscan for mode, will place upper left corner of screen at upper left corner of display clip (rather than centering screen around display clip. d=hhhhhhhh DISPLAYMODE=hhhhhhhh Ignore CAMG mode id if any and instead display using this mode id (where hhhhhhhh is hex mode id with no 0x or $) t=seconds TIMER=seconds For automatic advance when time elapses. The following options may be specified on a per-picture basis in a picture icon or in a line of a filelist: CLI opt Tooltype ======= ======== e EHB=TRUE n NOTRANSB=TRUE v VIDEO=TRUE a AUTOSCROLL=TRUE f BESTFIT=TRUE s NOMONITOR=TRUE r NOCENTER=TRUE d=hhhhhhhh DISPLAYMODE=hhhhhhhh Most other options are global and may only be specified on a CLI command line, or in the Display icon, or in a filelist Project icon. Examples ======== - Print three files as a background task: run Display file1 file2 file3 opt bp t=1 - Display a list of files as a looping (l) slide show, showing each picture for 5 seconds: Display from myshow opt l t=5 where the text file "myshow" contains: path/mypicture1 path/mypicture2 opt a d=00008004 (extra options for this picture) path/mypicture3 - Start a mouse-advance slideshow for a presentation Display from myshow opt ml Note - if you put a project icon on the file "myshow", set its Default Tool to Display, and enter the tooltypes MOUSE=TRUE and LOOP=TRUE, you could start the same slide show by double-clicking the Project icon.
