Parameters

iOS / macOS

Use the ConvertFromCGImageAsync method to convert a CGImage into a LEADTOOLS LTRasterImage asynchronously. The conversion works by copying the image data over to the new destination. Currently, there is no support for sharing memory between a LTRasterImage and a CGImage. This method returns immediately and does the image conversion asynchronously in a queue
