Standard Questions
Q: Is there a Win95 or WinNT version of GraphX?
A: GraphX is a 16-bit product, it will run under Windows
3.1, Win95, and WinNT 3.x. It has never been tested under NT 4.x. If you are interested
in a more robust 32-bit product, then we suggest checking out our commercial products,
most notably WebImage, a superset of GraphX.
Q: Can I redistribute GraphX?
A: You CANNOT redistribute or resell the product or use it as a value-added software component to any product
or service you are selling. You CANNOT distribute the product under any different name or distribute the product as your
own. Group 42, Inc. holds all rights, license, and trademark to the software and its name.

Q: Do you have any special terms for reselling?
A: If you are interested in distributing the product in a "for-profit"
capacity, please contact us at info@group42.com We can discuss
the terms of such a venture.
Known Problems
Q: GraphX is not able to load and display some of my JPEG
images?
A: There is a new version of the JPEG spec, v6, that was released after GraphX
was created. Some JPEG are now starting to appear in this format. GraphX cannot
read them. Our WebImage product does support JPEG v6.
Q: When building a catalog, I get a "Divide by Zero"
error?
A: The GraphX thumbnailer will crash when encountering images that have a very
large width dimension and a very small height dimension (i.e. 800x3). This is
often seen in images that are used as separators on web pages. You can load the
image into GraphX, you just cannot make a thumbnail of it. You will need to move
the offending image(s) into a different directory before being able to build a
thumbnail catalog.
Q: I cannot get the OPEN dialog to display?
Q: I get an "OWL Exception" error and the product crashes?
A: You are running into a conflict with our BWCC.DLL file and an older or invalid
version of BWCC.DLL on your system. Another product you are running is loading
an older version of BWCC.DLL. When GraphX starts, it recognizes BWCC.DLL as loaded
and tries unsuccesfully to utilize the incorrect version. Try the following:
- Search your hard drive for a BWCC.DLL file, you’ll most likely find it in
your \windows\system directory.
- Rename any BWCC.DLL files to BWCC.TMP
- You may have a program like Norton Desktop or a screen saver which has BWCC.DLL
loaded at startup. You'll need to exit these programs to rename the BWCC.DLL file.
- Reinstall GraphX Viewer.
- Restart Windows and then check the functionality of GraphX.
Product Functionality
Q: When I load an image, I only get a black square?
Q: When I load an image, I get strange colors in the image?
A: While it’s possible that the image is either a black square or has funky colors,
what your probably experiencing is running GraphX on a VGA display. GraphX requires
a minimum SVGA display. This provides 8-bit, 256 colors. Your display is probably
set to 4-bit VGA, 16 colors or is monochrome. It’s quite possible that your display
can be set to 256 colors. Consult your computer’s manual on adjusting your display
settings.
Q: I can't decode a file posted to a UseNet group?
A: UseNet postings are a hit/miss proposition. Unfortunately, a high number of
postings are performed incorrectly, get corrupted, or are invalid files. Keeping
that in mind, there is a new encoding method called Base64 that GV cannot decode.
Look at the downloaded text file in a text editor and see if you can located "Base64"
somewhere in the header information. If not, make sure that file starts with a
BEGIN statement and ends with an END statement. Also, check to verify the filename
given after the BEGIN statement is in a valid format (i.e. xxxxxxxx.xxx for Windows).
After that, you'll probably have to give it up for lost, since verifying an encoded
file is anything but easy.
Q: When I run another application, all my colors change
and/or shift?
A: If you are running on an 8-bit (256 color) display this is a common occurrence
among graphics packages. Only 256 colors can be made visible at one time, and
the current application will reset the palette to its desired color selections.
Some applications don't properly release the palette when toggling between products.
If so, try exiting that application for best results.
Q: My color reduction seems blotchy?
A: In GraphX, check the reduction method you are using. Dithering will produce
the best looking results, while Matching may create a blotchy appearance. Next,
verify the reduction level. Reducing a 24-bit image (16.7 million colors) to 4
colors is certainly going to show noticeable degradation. Last, some images (due
to color content) just don't reduce well. Try a variety of reductions. For example,
a reduction to 50 colors may just cross that acceptable threshold, but a reduction
to 55 colors may look amazingly better.
Q: When I resize an image, it gets blurry?
A: Sizing an image larger requires that content be interpolated and added. Decreasing
the size requires that content be removed. In both cases, a certain bluriness
might be detectable, notably on large changes. A good rule of thumb is to always
resize proportionally, and always resize within reasonable limits.
Q: If is save to 50 colors, why are fewer colors used?
A: Sometimes the color reduction routine requires fewer colors than the number
defined when color reducing an image.
Q: Does GraphX support postscript/EPS files?
A: GraphX will export a postscript or EPS file, but it does not read them.
Web Browsers
Q: How can I use GraphX with Netscape.
A: Define GraphX as the "helper" or "external viewer" in
your Web browser. You may need to do this for a number of the supported image
types including GIF, JPEG, PNG, and TIF. By doing this, when you select an image,
it will load directly into GraphX, allowing you to manipulate the image, resize,
or save in a variety of formats....things you can't do in Netscape/Mosaic.
Q: How can I download an in-line image from a web page?
A: Make sure that GraphX is defined as a "helper" or "external
viewer" in your Web browser. Using Netscape, right click on the image you
desire to download. From the pop-up menu, select "View this Image" or
"Save this Image As".
