  "description": "The Contrast And Brightness function enhances the appearance of raster data by modifying the brightness and contrast within the image. Brightness increases the overall lightness of the image\u2014for example, making dark colors lighter and light colors whiter\u2014while contrast adjusts the difference between the darkest and lightest colors.<div><br />Using this function alters the pixel values; therefore, this function should be used when you want to enhance the appearance of the data and not if you intend to use the data as part of an analysis that would require the raw pixel values. This function is useful when publishing the data as an image service that may be used in applications without the ability to alter the contrast and brightness of the imagery, or to ensure that it displays using your preferred settings.<\/div>",
