- USING THE SSC, FOC, AND THUMBNAILS: A Tutorial on PMView 0.86
- =============================================================
-
- This tutorial will help show off the power, flexibility, and ease of
- use of the new File Open Container, Slideshow Container, and
- thumbnails.
-
- Start by entering PMVIEW at an OS/2 prompt. (Or, if you've made an
- icon, double-click the icon). Don't specify a filename. PMView will
- start up, with an empty black window.
-
- The black window means that we are in Image mode. One major difference
- between PMView 0.86 and earlier versions is that there are two main
- modes: image mode and slideshow mode. (Older versions only had image
- mode.)
-
- Let's load an image. Select _File _Open from the menu bar, or type
- Ctrl+O. This will bring up the File Open dialog. If there aren't any
- image files in your current directory, please change to a directory
- that has several image files.
-
- PMView's file open dialog should look much like the standard OS/2
- file open dialog, with one major exception -- the large white area in
- the lower left corner shows icons and text, rather than just a list of
- text. This large white area is the File Open Container, and it's one
- of the major new features of PMView 0.86.
-
- The File Open Container (FOC) is a standard OS/2 container. It
- has its own settings that you reach in the standard way. Please try
- that now: Move the mouse to a part of the FOC that doesn't have any
- icons, and right-click. A menu will pop up that will have "Views" as
- its top item. (If you get a menu that starts with "Open," you've got
- the menu for an icon. Move to an empty spot and try again. If you
- can't find an empty spot, try resizing the File Open dialog; when the
- FOC resizes, you'll probably find an empty spot.)
-
- By default, PMView started with the FOC in icon view. Try switching to
- text view (by clicking "Views" and then selecting "Text." This takes
- the icons away and gives you a single column of filenames: It looks
- almost exactly like the standard OS/2 file open dialog. Try some of
- the other views, picking the one you like best. (My preference is
- "Icon"; one of my friends prefers "Detail.")
-
- While the standard-sized OS/2 icons are okay, PMView's new thumbnails
- are better. To see them, go into a FOC view mode other than text (or
- text, flowed ;-) and select "Views" from the FOC popup. Click
- _Thumbnails to turn it on (it's at the bottom of the menu). The small
- OS/2 icons will be replaced by larger, more legible thumbnails.
-
- All the thumbnails currently say, "No Thumbnail Available," but we'll
- fix that now. Right-click on one of the images to bring up its popup
- menu. Click "_Thumbnail" (for now, *don't* click on the arrow). The
- thumbnail will turn blue, and it will say "Creating Thumbnail." After
- a few seconds (or minutes, depending on the size of the file), you
- will see a small version of the image. A thumbnail is attached to the
- file's extended attributes; it takes up 9540 bytes. Note that PMView
- also attaches a standard icon to the file; if you look at the file
- using a Drives object, you can see it. (Or, of course, you can toggle
- the Thumbnail view off for the FOC.) This icon behaves just like you'd
- expect; for example, you can set a desktop object's icon by dragging
- the file from a Drives object to the icon on the _General page.
-
- There are three other things you can pick off an icon's popup menu. If
- you click on the arrow to the right of _Thumbnail, you can also choose
- to delete the object's current thumbnail (thus freeing up the 9K the
- thumbnail takes). Or you can click Delete to delete the file. (PMView
- will ask for verification). Finally, you can click Open to load the
- image into PMView. Try that now (preferably with an image that won't
- take too long to load).
-
- There's one other thing you can do to an icon, though not by clicking a
- menu item: Just like on the OS/2 desktop, you can rename a file by
- Alt+Left mouse click on the filename. You might want to try this now.
-
- Let's get back to the FOC popup menu. Click "Thumbnails." You can
- choose _Manual Create, _Automatic Create, or _Loading Creates. The
- first means that thumbnails are created only if you right-click on the
- icon and choose _Thumbnail Create. If you choose _Automatic Create,
- then whenever you enter a directory, PMView will split off threads to
- automatically create thumbnails for every image file in that directory.
- This can be convenient, but it can also bog down your system! My
- preference is to use _Loading Creates: This creates a thumbnail
- automatically for each file you open and view in PMView.
-
- The other option under _Thumbnails is Transparent _Fill. If it's on,
- PMView creates square thumbnails with "transparent" areas where there's
- no image. If it's off, these areas are created black.
-
- The other two commands on the FOC's menu should be self-explanatory:
- _Refresh rereads the files in the current directory (in case you've
- added or deleted files from another OS/2 session). S_elect gives you a
- quick way to select (or deselect) all the files in the current
- directory.
-
-

-
- We've discussed thumbnails and the FOC; time to talk about the
- SlideShow Container (SSC, with apologies to physicists). To open the
- SSC, select _File _New _Slideshow from PMView's menu bar (or PMView's
- RMB popup menu). PMView's main window will turn white, which shows that
- you're in Slideshow mode. Now do Ctrl+O to get to the FOC. To add
- images to your current slideshow, drag them from the FOC. To change
- their ordering, drag them around. If you drop an icon on top of another
- icon, it will go after that icon in the slideshow. Thus, moving an icon
- to the beginning of the slideshow takes two operations: You should drop
- it on the first icon, and then drop the first icon on top of it. (This
- is easier done than said.)
-
- I could say more about the SSC's popup menu but I'll leave it to you to
- discover. The only item I'll point out is R_un, which runs the
- slideshow. Click on the arrow to the right of R_un to set the slideshow
- run options. (The slideshow run options are documented in detail in
- PMVIEW.DOC.)
-
- As with the FOC, each separate image has its own settings, and you
- click the right mouse button to bring up the appropriate menu. Then
- click Settings.... The three things you can do are change whether the
- slideshow will wait for you to press a key before advancing to the next
- image (this is "manual") or it will move forward automatically after a
- time delay that you specify. You can also enter notes for each image.
- Finally, you can check the "Display Notes" box if you want the notes to
- appear onscreen during the slideshow.
-
- Whew! There's more I could say but it's getting *really* late. The best
- way to learn more about PMView's new slideshow/file open features is to
- experiment. Hope you have fun!
