AcMapQueryPE:: transformBy Method
Transforms the entity (projection transformation during query and save back, and rubber-sheeting).
virtual Acad::ErrorStatus transformBy(
AcDbEntity * pEnt,
bool bMirror,
bool bSimple,
Acad::ErrorStatus (*getMatrixInPoint) (AcGeMatrix3d &mat, bool bUniScaleOrtho, const AcGePoint3d &p)
);|
Parameters |
Description |
|
pEnt |
The entity. |
|
bSimple |
Output true if transformation matrix is constant, and you can call regular transformBy(). |
|
bMirrow |
Output true if you are rubber-sheeting and you need to swap all angles and bulges. |
|
getMatrixInPoint |
Callback function to calculate transformation matrix at the specified point. |
|
mat |
Output the result matrix. |
|
bUniScaleOrtho |
Output true if you need the matrix to be isUniScaledOrtho() because rubber-sheeting will create a non-orthogonal matrix. |
|
p |
The point to calculate matrix at. |
Returns
Returns Acad::eOk on success.
Remarks
This is non-linear transformation, where matrix is different in the different points. Default implementation calculates a constant matrix at some middle point on the entity, and calls AcDbEntity::transformBy() with that constant matrix.
