L_LVKRN_API L_INT L_VecApplyTransformation( pVector)
Applies the current transformation to the vector image. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.
Pointer to a vector handle referencing an image drawing.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
This function will apply the current transformation (Rotation, scaling and translation) to the vector image. The vector image objects will be changed.
After a call to this function, rotation, scaling and translation values will be reset.
Required DLLs and Libraries
This example loads a vector drawing, applies some transformation then saves it back.
