Modifies and analyzes Bitmap image
Syntax
Remarks
Image property contains an internal representation of the image. All image processing methods are applied to this image.
Before use, it should be assigned an initialized CiImage object or initialized using CiImage.Open, CiImage.Copy, CiImage.Create or CiImage.CreateBpp methods.. Alternatively, Image can be initialized by using ImageEditor(Bitmap) constructor or assigning Bitmap property.
When processing is done save the image to a file using CiImage.SaveAs or CiImage.Append methods and/or obtained through Bitmap property.
Alternatively read barcode on pre-processed image using BarcodeReader.Read(ImageEditor) method.
Image also can be assigned ClearImage.CiRepair.Image or ClearImage.CiTools.Image properties to perform lower level image processing functions, not exposed in ImageEditor class.
