Parameters

image
The UIImage/NSImage to be converted

options
Instance of LTConvertFromImageOptions to control the conversion operation.

error
Pointer to an NSError

Return Value

A LTRasterImage object representing the converted image.

Remarks

iOS / macOS

Use the ConvertFromImage method to convert either a UIImage or an NSImage into a LEADTOOLS LTRasterImage (**see note below). 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 UIImage/NSImage.
