The CONV2JPG.EXE is a Win32 command-line program that converts and/or resizes
almost any image or graphics file format to a 24-bit JPEG (JFIF compliant) file
with specified compression quality. It can for example be used to create low 
resolution previews (thumbnails) for WWW-server applications. It's ideal for 
automated batch or single graphics file conversions. The program works under 
Windows NT and Windows 95.

Usage: CONV2JPG.EXE [sourcefile] [destinationfile] [compression] [size]

	[sourcefile]: filename of the input graphics file (MANDATORY)
	[destinationfile]: filename of the output JPEG file (MANDATORY)
	[compression]: compression quality, 2-255 (255 is maximum compression)
		      default=50 (OPTIONAL)
	[size]: maximum horisontal/vertical size in pixels, if omitted, the 
		infiles horisontal/vertical size is used (OPTIONAL)

NOTE! Only the destination filename will accept wildcards and only in the
      following formats: "*.ext" "*.*" "*." "filename.*"

Example:CONV2JPG e:\images\jordan.gif e:\images\*.jpg 150 128
    this example creates a file called jordan.jpg with the height or width of 
    128 pixels depending on which side is the longest. The file is compressed
    with a compression factor of 150. With this resize-feature it is easy to 
    create previews or thumbnails that fits into a predefined grid, like an 
    imagebrowser.

See the file EXAMPLES.TXT for further examples on how to use CONV2JPG.
	
System requirements:
-Any system which can run Intel Win32 applications.
-Enough RAM memory to hold the image data. If the computers RAM is full, then
the program stores the temporary imagedata in the TEMP directory. This 
greatly slows the conversion speed down.
The CONV2JPG.EXE uses the supplied LEAD52N.DLL which have to be reachable.

The program does not care about file extensions. We recommend that you name 
the output JPEG-file with the extension .JPG or .JIF for compability with 
other applications. This program has a 10-second termination time delay in 
order to make you more motivated to purchase the fully working version. 
The full version can also be "quiet", without file information.

The program supports the following graphics formats:

PCD  Kodak PhotoCD files.
JFIF JPEG File Interchange Format. 
JPEG Joint Photographers Expert Group file format.

It does not however support every flavour of all the fileformats listed. 
You have to try out the program to see if it solves your specific problem.

If you are interested, we have a program which can output not only JPEG 
images, but any of the fileformats listed above. It's called XCONVERT.

We also have a "watermark"-program that superimposes a "relief" image, for 
example a logo, over an image for copyright purposes. Lets say you would like 
to publish pictures on the internet but you don't want the client to be able 
to use the preview images.

RANG Microsystems has a long experiance in Internet/Intranet, communications
and graphics solutions. We are especially experianced in solutions for 
newspapers and newsagencies (IPTC is our second language).

NOTE! This shareware version writes a special "tag" on the output JPEG image
which is invisable to other programs. This is not done on the full version.
We have done this in order to track the spread of this program on the Internet.
