PixFolio - Windows Image Viewer and Catalog Manager (Shareware)
PixFolio (formerly ShowGif) is a Microsoft Windows program that can view a
variety of bitmapped graphics formats and maintain multiple catalogs of
images. Version 1.01 is being distributed as Shareware for $25.00 by the
author, Allen C. Kempe. You are free to use PixFolio for a 30 day period.
After that time, you are expected to register your copy and pay the $25.00
registration fee.
The graphics formats currently supported are:
IFF - IFF/LBM (Amiga) used by Computer Eyes frame grabber.
TIFF- Tag Image Format. Most formats including 24 bit color
are supported.
PCX - Microsoft Paint & PC Paintbrush
TGA - Targa
GIF - CompuServe Graphics Interchange Format
BMP - Windows Bitmap
RLE - Windows Run Length Encoded
Note: Not all variations that may be possible in the above file formats have
been tested due to lack of suitable test files.
The major feature of PixFolio is the ability to build catalogs of
images, that may reside on different disks. The catalog can then be searched
and images can be easily located. Provisions are made for saving a primary and
backup location for the image concurrently. To enhance searching for a
particular image the program can display postage stamp images in a matrix.
The ability to read an image in one format and to save it in another allows
the program to be used as a file conversion utility.
PixFolio version 1.01 is Shareware (see the accompanying file "PIXREGST.ME").
PixFolio may be freely distributed on Bulletin Boards so long as all files
are included along with this file.

THIS PROGRAM'S FITNESS OR SUITABILITY FOR ANY PURPOSE. ALL USERS SHOULD USE
IT AT THEIR OWN RISK.
The author will make a reasonable effort to correct problems and software
bugs relating to documented features of the program for registered users.
The author intends to make continuing improvements to the program including
supporting additional file formats. To this end, comments and suggestions are
welcomed.

******** Equipment Requirements **********
While PixFolio will execute in a minimal Windows installation, for example, a
286 with 1 megabyte of memory, program operation will be severely inhibited by a
lack of memory. On such a configuration, large bitmaps, especially 8 or 24
bit images will fail. Other applications could be adversely affected as well.
Actual results will vary depending upon the amount of memory used by other
applications running concurrently.
PixFolio was developed and tested on a 20-MHz 386 with 8 megabytes of memory.
It is recommended that PixFolio be run on a machine with at least 2 and pre-
ferrably, 4 megabytes of memory. Running in 386-Enhanced mode will also
make available the benefits of virtual memory.
The display of images containing more than 16 colors requires that you have
a Super VGA or better video display and a 256 color Windows device driver.
Future versions of PixFolio may incorporate dithering functions that would
allow display of a 256 color image using a 16 color driver such as the
standard VGA driver distributed with Windows. This version of PixFolio will
display such images using whichever of the 16 colors that Windows uses are
closest. The results of this can be disappointing.
********** Program Limitations *************
PixFolio has no limit on the number of catalogs that can be created or the
size of these catalogs. However, the following points should be noted:
1. Catalog indexes are read into memory whenever a new catalog is selected.
Large catalogs with many entries could result in lengthy delays whenever
a catalog is opened or a search is initiated. The author has maintained
catalogs with over 150 entries without encountering unacceptable delays.
2. The size of a catalog is otherwise limited by the amount of disk space
where it resides. Catalog records are variable length and depend upon
the type of image and how big the comments are.
3. PixFolio may encounter difficulty with extremely large images, those in
excess of 1024 x 768 pixels. This is particularly true of color images
and even more so by 24 bit color or gray scale images. This is primarily
due to the increased memory requirements. There is a known problem creating
the "postage stamp" image for a large bitmap; this is believed to be a
problem with the video device driver's StretchBlt function.
4. While PixFolio and Windows supports 24 bit color and gray scale images,
the display of such images using a video driver that only displays 256
colors, can result in some lengthy delays whenever windows has to realize
the 24 bit RGB data to an 8 bit palette. It may take 15 to 20 minutes to
realize a 640 x 480 image depending upon the speed of your machine.
5. The support for GIF animation in PixFolio requires large amounts of free
memory. GIF animation files with a large number of frames or overlays may
unexpectedly fail when PixFolio runs out of memory.
6. PixFolio has not been tested nor has it been designed to work in a network
environment. The affect of network operations and more than one user
accessing PixFolio files concurrently cannot be predicted.
7. Not all graphics formats are supported equally with respect to reading and
saving a file. For example, none of the compression options are currently
supported for saving TIFF images. GIF images can only be saved in GIF87a
format. Likewise, some of the more obscure or obsolete formats such as 4
color CGA formats for PCX cannot be written although they can be read.
8. Other program limitations, if any, can be determined by accessing the
online context-sensitive help.
******** NOTE **********
If you have previously loaded Showgif (the former name of this program), you
should edit your WIN.INI file changing the section name [Showgif] to
[PixFolio]. Catalog file names, e.g. SHOWGIF.CAT need not be renamed but if
you do, be sure to rename the index file, SHOWGIF.CIX also!
****** Installation and Getting Started*******
It is suggested that the files which constitute PixFolio be placed in their
own subdirectory on your hard disk. These files are:
PIXFOLIO.EXE
PIXFOLIO.HLP
SPIN.DLL
METER.DLL
Not necessary for program operation are this file PIXREAD.ME, PIXREGST.FRM
and PIXREGST.ME. PIXPACK.LST is a list of files included in this zip file.
Once the above files have been located in the subdirectory of your choice,
start Windows and then use the Program Manager "Add" command to add PixFolio
to the desired program group.
When PixFolio runs for the first time, it will establish a section in
your WIN.INI file with program variables. These default options should enable
you to start using PixFolio immediately. Once PixFolio is running you may
access the online Help command for specific instructions and explanation of
PixFolio menu commands.
A quick review of PixFolio features and operating procedures can be gained by
selecting "User Guide" under "Help".
****** Credits ******
The author of PixFolio would like to recognize the efforts of Mr. Paul Hachey,
(CompuServe Id 76247,3716) who performed an invaluable service by getting
deeply involved in the extensive testing that went on over a period of months.
Paul is responsible for the design of the PixFolio cover page, Icon and
"About" dialog box and his many suggestions greatly influenced the "look and
feel" of PixFolio.
