Description
Copies current image to the specified destination.
| Parameter | Description |
| dest | The TIEVisionImage to copy from |
| mask | A TIEVisionImage specifying which pixels to copy (pixels > 0 in the mask will be copied) |
| srcRect | The area of this image to copy |
| dstRect | The area where the copied image will be drawn |
| destPtr | Copy to a buffer rather than an image |
| rowLen | The row length for the buffer |
Example
// overload nr.1: copies image1 to destination, using specified mask (only pixels with mask > 0)
destination := IEVisionLib.createImage();
image1.copy(destination, mask);
// overload nr.2: copies image1 to destination
destination := IEVisionLib.createImage();
image1.copy(destination);
// overload nr.3: copies specified rectangle of image1 to destination
destination := IEVisionLib.createImage();
image1.copy(IEVisionRect(10, 10, 200, 200), destination);
// overload nr.4: creates a new image from the specified rectangle
destination := image1.copy(IEVisionRect(10, 10, 200, 200));
// overload nr.5: copies specified rectangle of image1 to specified rectangle of destination
destination := IEVisionLib.createImage();
image1.copy(IEVisionRect(10, 10, 200, 200), IEVisionRect(50, 50, 200, 200), destination);
// overload nr.6: copies specified rectangle to destination buffer
image1.copy(IEVisionRect(10, 10, 200, 200), destPointer, destRowLen);
