# CropImage Method of the ImageDocument Object

This method finds the edges of a document on the image and then crops the image. We recommend that you call this method at the beginning of image preprocessing, before making any other modifications.

<Note>
  This method does not work with black-and-white image documents (those for which [ImageColorType](/fine-reader/engine/api-reference/image-related-objects/imagedocument#imagecolortype) is ICT\_BlackWhite).
</Note>
