TIEVisionImage.addWeighted
Declaration
procedure addWeighted(alpha: double; rhs: TIEVisionImage; beta: double; gamma: double; dest: TIEVisionImage); overload; safecall;
Description
Calculate the weighted sum of two images, executing: dest = this*alpha + rhs*beta + gamma
| Parameter | Description |
| alpha | Weight for the first image pixels |
| rhs | Second source image of the same size and channel number |
| beta | Weight for the second image pixels |
| gamma | Scalar added to each sum |
| dest | Container for the resulting image |
Note:
◼The source images must be the same size and color depth
◼You should allocate the destination image to the same size as the source images
