TIEVisionImage.convertScale
Declaration
function convertScale(dest: TIEVisionImage; scale: double = 1.0; shift: double = 0.0): TIEVisionImage; overload; safecall;
function convertScale(channelFormat: TIEVisionChannelFormat; scale: double = 1.0; shift: double = 0.0): TIEVisionImage; overload; safecall;
Description
Convert an image to another datatype with optional scaling.

Second overload updates the current image. It returns itself.
| Parameter | Description |
| dest | Container used to store results |
