virtual L_INT LBitmapBase::RectToBitmap(nViewPerspective, pRect)
L_INT nViewPerspective; |
/* source view perspective*/ |
LPRECT pRect; |
/* pointer to the RECT structure to be translated*/ |
Translates a Windows RECT structure from a specified view perspective to the bitmap's view perspective.
Parameter |
Description |
nViewPerspective |
Source view perspective from which the rectangle coordinates should be translated. |
pRect |
Pointer to the RECT structure to be translated. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
To use this function, do the following:
1. |
Declare a Windows RECT structure and a pointer to it. |
2. |
Assign the values of the rectangle. |
3. |
Call this function, passing the pointer to the RECT structure, and specifying the source view perspective. (The function gets the destination view perspective from the bitmap handle.) |
4. |
Get the translated rectangle from the RECT structure, which this function has updated. |
