Parameters

iOS / macOS

Use the ConvertToCGImageAsync method to convert a LEADTOOLS LTRasterImage into a CGImage 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 CGImage. This method returns immediately and does the image conversion asynchronously in a queue
