Parameter |
Description |
|
hRgn |
Windows region representing one of the holes of the hole punch pattern. It is the programmers responsibility to delete this region (using DeleteObject())when it is no longer needed. |
|
pBoundingRect |
Pointer to a RECT structure that contains the bounding rectangle of one of the holes in a hole punch pattern. |
|
iHoleIndex |
Index of the hole within a hole punch pattern. The holes are numbered from 1 to n, where n is the total number of holes in the hole punch pattern. |
|
iHoleTotalCount |
The total number of holes that make up the hole punch pattern. This value will not change for a particular call to LBitmap::HolePunchRemove(). |
|
iWhiteCount |
Total number of white pixels in one of the holes of a hole punch pattern. |
|
iBlackCount |
Total number of black pixels in one of the holes of a hole punch pattern. |
Returns
|
SUCCESS_REMOVE |
Remove the hole. |
|
SUCCESS_NOREMOVE |
Do not remove the hole. |
|
Otherwise |
An error occurred. Refer to Return Codes. |
Comments
This function is called once for each occurring hole in the hole punch configuration. For example, if there are three holes, the callback gets called three times. Return SUCCESS_REMOVE to have a particular hole removed. Return SUCCESS_NOREMOVE to leave the hole unchanged. Pass any other value to abort. This value will be the return value of the LBitmap::HolePunchRemove(). If HOLEPUNCH_IMAGE_UNCHANGED and HOLEPUNCH_SINGLE_REGION are being used, then the return value of this function affects only the internal single region that contains all the changes.
