Available Tools

The tools described below will help you create a RealPix presentation. These tools are public domain applications available from RealNetworks and many Internet software archives.

CJPEG

CJPEG is a JPEG compression tool you run from the command line on Windows 32-bit operating systems. It is useful if you have no other image editing software to create JPEG files. It takes as input Windows bitmap (.BMP) or Targa (.TGA) format files and compresses them into JPEG files (.JPG). Run the tool with this syntax:


cjpeg -outfile output.jpg -quality X -restart 1B input.bmp

Here, X is the quality of compression in the range from 1 to 100. The practical range of JPEG quality is approximately 40-90.

JPEGTRAN

JPEGTRAN optimizes existing JPEG (.JPG) images for streaming with RealPix. You can run this tool from the command line on Windows 32-bit operating systems. Process existing JPEG images with this tool before streaming them with RealPix. The JPEGTRAN syntax is:


jpegtran -restart 1B -outfile output.jpg input.jpg

Note
If you produced your JPEG images with CJPEG, you do not need to run JPEGTRAN on them.
