Tips

• When you construct a class that inherits from the ImageAdapter class, you must implement this method.

• blockproc does not call the close method. If your image adapter opens file handles or requires other class clean-up responsibilities, then you must call the close method explicitly in your image processing pipeline.

Version History

Introduced in R2010a

R2026b: ImageAdapter.close is not recommended

The close method of the ImageAdapter class is not recommended. Instead of ImageAdapter, use a blockedImage object. The blockedImage provides several advantages, including built-in adapters for common image formats. For non-standard formats, you can create a custom adapter by using the images.blocked.Adapter class.
