Contrast Stretch

Description:

This simple RCO provides interactive contrast stretching on an image. This can sometimes make features not easily visible in the original image stand out better.

The instructor must provide an image in a standard web format (such as .gif or .jpg).

The sample XML file provided below must be populated with appropriate data (in this case, the image file name is all that is required) and placed in the same location as the HTML file used to access and present this RCO.
