Noch´n Programm von Nico Francois ist das vorliegende PPShow, welches in der Lage ist, gecrunchte(!) ILBM-Bilder anzuzeigen! PPShow kann sowohl von der Workbench wie auch vom CLI aus gestartet werden. Die Tab-Taste beinhält ein Color-Cycling. Rechte Maustaste (oder irgendein Tastendruck) zum Verlassen des Bildes. h- Option für HAM-Bilder ohne CAMG beachten! Anschließend die Originalanleitung! ........................................................................... PPShow 1.0 User Manual Jan 1, 1990 Preface ======= This program is freeware, this means that you can copy it freely as long as you don't ask any more money for it than a nominal fee for copying. If you want to distribute this program you should keep this document with it. If you have suggestions or remarks about this program, or if you find any bugs, please let me know. Write to the following address: Nico François Corbielaan 13 3060 Bertem BELGIUM Contents ======== 1. An introduction 2. Usage 3. Features 4. Note on crunching 1. An introduction ================== PPShow was written to complement one of my other utilities, PowerPacker (a command and data cruncher). It is used to show normal IFF ILBM files or ILBM files crunched with PowerPacker. The decrunching is done automatically so the user doesn't have to know if a file is crunched or not. If you haven't got PowerPacker you are of course missing one of the main features of this program. You can try to find it in your favourite public domain library or you can get it by writing to my address and adding $15 US (if you live in Europe), $20 US (if you live elsewhere). Send money in cash, by international money order or by EuroCheck (only in Belgian Francs (BF) !!) (Please don't send other checks). PowerPacker was published in the November 89 issue of JumpDisk and can be found on one of the Antares RD or Fish disks as well as on several other PD disks. 2. Usage ======== PPShow can be used in three different ways. - First of all via the CLI: If you enter PPShow without arguments you will get a usage template. You use PPShow like this: PPShow [] The program will then load the ILBM file and display it. If the file was crunched using PowerPacker 2.0 or higher PPShow will first decrunch it for you. If the file was encrypted you will be prompted for the password. There is only one option in this version: '-h'. This option is used to force HAM mode when no CAMG chunk is found. If you don't specify this option PPShow will assume a 6 plane screen is extra half brite. (Note that it is wrong for an Amiga IFF ILBM file not to have a CAMG chunk, especially when there can be doubt about what display mode to pick !) PPShow can be made resident so it doesn't have to be loaded every time you use it, use the ARP ARes command or the WB1.3 Resident command for this. You can't make PPShow resident when it is crunched !! The file is supplied as an uncrunched command file with the pure bit set. PPShow is reentrant as well, so you can run it from several CLI's at the same time. (Not that this is very useful, but it's possible :-D) Example: '1> PPShow -h dh0:pics/HAMpicWithoutCAMG.pic' - Via the WorkBench: There are three different ways of using PPShow via the workbench: you can set the default tool of the (crunched) ILBM file to 'PPShow', you can single click the PPShow icon and then double click the picture icon or you can double-click the PPShow icon and enter the filename in the string gadget you will be presented with. You set the default tool by single clicking the icon of the picture and selecting 'Info' from the workbench menu. You will get a window with several gadgets in it, click in the string gadget where it says 'Default tool' and enter ':ppshow'. PPShow should be in the root directory of your disk for this to work, if e.g. it's in the system directory you should enter ':system/ppshow'. Last of all select the 'Save' gadget. NOTE: - PPShow will add '.pp' to the filename when the file wasn't found. This is very useful in the WorkBench enviroment: you can make an icon for 'house.pic' but name the file 'house.pic.pp'. Now the WorkBench will show an icon with 'house.pic' as name, but if you doubleclick it 'house.pic.pp' will be displayed. (As long as there is no 'house.pic' file in the directory !) 3. Features =========== - Abort PPShow by pressing any key (except or 'P') or the right mouse button. The screen can be dragged by an invisible drag bar at the top. - The pesky little mouse will be removed while displaying. - PPShow offers full overscan support, PAL or NTSC. As far as I know this is the first ILBM viewing program to do so, looks like PAL Amiga owners still get forgotten. All Amiga display modes (like HAM, EHB) are of course also supported. - Deluxe Paint cycling is supported, press to (de)activate. Up to 8 cycles are supported (DPaint III currently only supports 6). - PPShow has the ability to print the screen it is displaying, all you have to do is press 'P' on the keyboard and wait. The mouse pointer will be visible while printing. Please note that the printer.device has to be in the 'devs:' directory for PPShow to be able to print, you should also have a correct system-configuration for your printer. 4. Note on crunching ==================== A lot of IFF ILBM files are already crunched with the standard ByteRun1 compression. PowerPacker will crunch these files even further (most of the time) but will not crunch them as well as uncrunched ILBM files. So save IFF files uncrunched (if you can, e.g. with PixMate) before crunching them, this way you will get the best crunching results. As always, I hope you find this program useful !
