typedef struct _PAINTTRANSFORM
{
L_INT nRotate;

} PAINTTRANSFORM, * pPAINTTRANSFORM
The PAINTTRANSFORM structure contains information used to transform (scale and rotate) coordinates.
Member | Description | |
nRotate | Rotation angle. The angle is in degrees, counter-clockwise. | |
Scale | Scaling factor. | |
cx will be used to scale the coordinates in the horizontal direction. | ||
cy will be used to scale the coordinates in the vertical direction. | ||
Valid values are between 1 and 10000, For example: | ||
Value | Meaning | |
100 | the same. | |
110 | 1.1 times the original dimensions | |
120 | 1.2 times the original dimensions up to | |
10000 | 100 times larger than the original dimensions. | |
99 | 0.99 times the original dimensions, | |
98 | 0.98 times the original dimensions | |
