LBitmapBase::Shear
#include "ltwrappr.h"
virtual L_INT LBitmapBase::Shear(nAngle, bHorizontal=TRUE, crFill=0)
L_INT nAngle; |
/* angle of slant */ |
L_BOOL bHorizontal; |
/* flag that indicates the direction of the shear*/ |
COLORREF crFill; |
/* COLORREF value for the fill color */ |
Moves the corners of the class object's bitmap in the fashion of a parallelogram.
Parameter |
Description |
|
nAngle |
The angle of slant. Positive values are for clockwise angles; negative values are for counterclockwise angles. The angle is expressed in hundredths of degrees, with a limit of 4500 (45 degrees). |
|
bHorizontal |
Flag that indicates the direction of the shear. Possible values are: |
|
|
Value |
Meaning |
|
TRUE |
Horizontal shear. |
|
FALSE |

Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
You specify an angle of slant, horizontal or vertical shear, and the fill color for the created space. The following is a horizontal example:
The angle is expressed in hundredths of degrees, with a limit of 4500 (45 degrees).
