#include "ltwrappr.h"

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.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

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.

Not supported in DirectX engine.

Example

This example opens an image, rotates it, and saves the result as a .dxf file.

The vector is saved as transformed.
