L_LTANN_API L_INT L_AnnConvert(hContainer, pPoints, pAnnPoints, nCount, nConvert)
HANNOBJECT hContainer; |
handle to the annotation container |
LPPOINT pPoints; |
array of points in client coordinates |
pANNPOINT pAnnPoints; |
array of points in container coordinates |
L_INT nCount; |
number of points in the arrays (pPoints, pAnnPoints) |
L_INT nConvert; |
direction of conversion |
Use this function to convert back and forth between container coordinates and client coordinates.
| Parameter | Description | |
| hContainer | Handle to the annotation container | |
| pPoints | Array of points in client coordinates. Client coordinates factor in the current zoom factor, and the horizontal and vertical scrolling | |
| pAnnPoints | Array of points in container coordinates. Container coordinates are typically the same dimensions of the underlying bitmap, and are independent of zooming and scrolling. | |
| nCount | Number of points in the arrays (pPoints, pAnnPoints) | |
| nConvert | A value that specifies the direction of the conversion. Possible values are: | |
| Value | Meaning | |
| ANNCONVERT_TO_CONTAINER | [1] Convert to container coordinates | |
| ANNCONVERT_TO_CLIENT | [2] Convert to client coordinates | |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Use this function to convert back and forth between container coordinates and client coordinates.
The number of elements in both the pPoints and pAnnPoints arrays must be AT LEAST equal to nCount.
When nConvert is ANNCONVERT_TO_CONTAINER, the pPoints array must contain valid entries. If successful, pAnnPoints will contain the converted points.
When nConvert is ANNCONVERT_TO_CLIENT, the pAnnPoints array must contain valid entries. If successful, pPoints will contain the converted points.
