EnhMetaFileProc
The EnhMetaFileProc
function is an application-defined callback function that processes
enhanced-format metafile records. This function is called by the EnumEnhMetaFile function.
int CALLBACK EnhMetaFileProc(
|
HDC hDC, |
// handle to device
context |
|
HANDLETABLE FAR *lpHTable, |
// pointer to
metafile handle table |
|
ENHMETARECORD FAR *lpEMFR, |
// pointer to
metafile record |
|
int nObj, |
// count of objects
|
|
LPARAM lpData |
// pointer to
optional data |
|
); |
|
Parameters
hDC
Identifies
the device context passed to EnumEnhMetaFile.
lpHTable
Points to a
table of handles associated with the graphics objects (pens, brushes, and so
on) in the metafile. The first entry contains the enhanced-metafile handle.
lpEMFR
Points to one
of the records in the metafile. This record should not be modified. (If
modification is necessary, it should be performed on a copy of the record.)
nObj
Specifies the
number of objects with associated handles in the handle table.
lpData
Points to any
application-supplied data.
Return Values
This function
must return a nonzero value to continue enumeration; to stop enumeration, it
must return zero.
Remarks
An
application must register the callback function by passing its address to the EnumEnhMetaFile
function.
EnhMetaFileProc is a placeholder for the application-supplied
function name.
