                    options:(LTConvertToImageOptions)options  
                 completion:(void (^)(UIImage * __nullable image, NSError * __nullable error))completion 
macOS: 
+ (void)convertToImageAsync:(LTRasterImage *)image  
                    options:(LTConvertToImageOptions)options  
                 completion:(void (^)(NSImage * __nullable image, NSError * __nullable error))completion 

Parameters

image
The LTRasterImage to be converted

options
Instance of LTConvertToImageOptions to control the conversion operation.

completion
Handler that fires after conversion with the converted image if successful, or an error object if the conversion failed.

Remarks

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
