Parameters

iOS / macOS

This method converts a LEADTOOLS LTRasterImage object to either a UIImage or an NSImage asynchronously.

The conversion works by copying the image data over to the new destination. Currently, there is no support for sharing memory between an LTRasterImage and an UIImage/NSImage. This method returns immediately and does the image conversion asynchronously in a queue
