public void OptimizeDirectory(RasterCodecs codecs,string inputDirectory,string outputDirectory,ImageOptimizerOptions options,string fileExtensions,bool includeSubDirectories,ImageOptimizerDirectory directoryCallback)
codecs
The Leadtools.Codecs.RasterCodecs object used internally in the optimization operation to load an image and optimize it.
inputDirectory
A System.String that contains the full directory path to the images to be optimized.
outputDirectory
A System.String that contains the full directory path to be used when saving the optimized image(s).
options
The options used in the optimization process.
fileExtensions
A System.String that contains the extensions of the files to be optimized. For example:
includeSubDirectories
true to optimize sub-directories, false otherwise.
directoryCallback
Optional callback function that provides user information about the image(s) being optimized, such as the completion percentage for the current image being optimized, and the completion percentage for all files being optimized.
For more information, refer to Image Optimization Using The ImageOptimizer Class.
This example will optimize all Jpg files found in a specific directory, and save them into a separate folder
