virtual L_INT LVectorBase::ApplyTransformation(L_VOID)
Applies the current transformation to the vector image. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
This function will apply 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 opens an image, rotates it, and saves the result as a .dxf file.
The vector is saved as transformed.
