32 New Features in PMView 0.90
==============================
Here are some of the neat new things in PMView 0.90:
1. The shareware (unregistered) version is now fully functional. You
can now test all the features before registering (except the ability to
turn off the logo).
2. There is a new dialog for file saves. In addition to being able to
save BMP files and PMView slideshows, you can now save a bitmap using
GIF, JPEG, PCX, PIC, TGA, TIFF, or PBMPlus (PBM, PGM, and PPM) formats.
(And BMPs can now be saved in OS/2 1.x, OS/2 2.x, or Windows 3.x
format).
3. There is fully context-sensitive online help (just hit F1).
4. There is a new Convert to-> command on the File Open and Save popup
menus. This makes it convenient to batch convert images as a background
task.
5. You can now print! You can print an image across multiple pages,
adjust gamma for your printer, set up your printer, set up your page
margins using millimeters, inches, or percentages.
6. There are new filters, including user-definable filters. NOTE&colon.
The filter file format will change significantly in the next release of
PMView, so you should be prepared.
7. There is a palette editor, so that you can change the palette
entries on non-deep-color images.
8. You can now drag a rectangular area to cut, crop, or paste. An
optional Track Info dialog box tells you the exact size and location of
the selected area, and lets you type in a new location or size.
9. There is new support for reading and writing PBMPlus files (PBM,
PGM, and PPM).
10. Kodak Photo CD PRO files (6144x4096) can now be read.
11. There is support for more TIFF formats&colon. FAX3/2D, FAX4, and
Thunderscan compressions.
12. There is a completely new multithreaded method for painting the
PMView window. This usually requires 3-4 times less RAM(!) than the old
method and lets PMView display arbitrarily large bitmaps. (The old
method used a shadow bitmap and would have required approximately 120MB
of virtual memory to display a 40MB TIFF file. This is, in fact, more
than OS/2 PM can handle; trying to use a bitmap this large usually
makes the system hang. With the new method, you can display the same
bitmap with 45MB of free virtual memory.) However, since the new method
may be slower on certain display drivers, the old method is available
as an option in the settings notebook. Additionally, you can set an
image-size threshold to choose between display methods depending on the
image you want to view.
13. The new Edit mode allows you to load, view, and save images with
more colors than you can display. (View mode discards extra colors to
save memory, speed painting, and give the best display quality for your
screen mode.)
14. Dithering (to the screen or when reducing colors) is now
multithreaded.
15. Long file name support has been improved. PMView now displays the
long file name in the title bar and in all info dialogs. PMView also
handles the .LONGNAME extended attribute in full. So, for instance, you
can copy an image from an HPFS drive to a FAT drive (using the Drives
object), and PMView will display the long file name. It also means you
can give your images arbitrarily long names, even on FAT drives, and
PMView (and OS/2's drive object) will display these names. (Note that
OS/2's DIR command and many other programs will *not* display the long
names.)
16. If you wish, PMView can display physical file names instead of Long
File Names.
17. Support for 16-color systems has been improved. You can choose from
a variety of optional fixed palettes and dithering methods.
18. Support has been improved for 256 color systems without palette
manager. You can choose from a variety of optional fixed palettes and
dithering methods.
19. There is a new Solarize special effect.
20. You can now adjust Gamma for your screen. This can be very useful
when displaying images created on other computer systems (which often
look too dark or too bright).
21. You can reduce to black/white, 16 colors, or 256 colors. (The last command
includes an option to let you choose any number of colors between 0 and 256.)
22. The new "complete" Undo/Redo works on any operation that has
modified the image.
23. The bulky old progress bar has been replaced by an animated clock
mouse pointer. This saves screen space, RAM, and time.
24. You can now see color adjustments (brightness/contrast, gamma,
etc.) in real-time on systems with deep color or without palette
manager!
25. All the transform functions have been enhanced. The clock pointer
will show your progress, and you can cancel the operation at any time
by pressing ESC.
26. Transform functions now run in idle-time (with priority boost).
27. Priority boost has been enhanced to be less sensitive to "CPU hogs"
once the process has started. (Previous versions of PMView could boost
load priority unnecessarily due to a temporary "CPU hog".)
28. There are new command-line options. For instance, /WPOS lets you
control the initial size and position (including Z-order!) of PMView's
window.
29. There are new pages in the options notebook. The Confirmations lets
you choose whether to be warned when deleting files, discarding
changes, or stopping a batch conversion. The logo page (disabled on the
unregistered version) lets you select how long to display the opening
logo (or you can turn it off). And, by popular demand, a second page
has been added to the Slideshow page of the options notebook, so you
can set the defaults for new slides.
30. PMView can now interpolate pixels when resizing or rotating images.
This is a little slower, but the results look much better.
31. The File Open Container and Slideshow Container will now "auto
scroll" when you keep the left mouse button pressed and move outside
the container. This is very handy for selecting multiple files.
32. PMView has better support for national language conventions. For
instance, PMView will sort the names in the File Open box correctly
according to the country selected in OS/2. Dates, times, and numbers
will be displayed in the way that you have configured OS/2.
