Graphics.EnumerateMetafileProc Delegate

Definition

Namespace:

System.Drawing

Assembly:

System.Drawing.Common.dll

Provides a callback method for the EnumerateMetafile method.

public: delegate bool Graphics::EnumerateMetafileProc(EmfPlusRecordType recordType, int flags, int dataSize, IntPtr data, PlayRecordCallback ^ callbackData);

public delegate bool Graphics.EnumerateMetafileProc(EmfPlusRecordType recordType, int flags, int dataSize, IntPtr data, PlayRecordCallback? callbackData);

type Graphics.EnumerateMetafileProc = delegate of EmfPlusRecordType * int * int * nativeint * PlayRecordCallback -> bool

Public Delegate Function Graphics.EnumerateMetafileProc(recordType As EmfPlusRecordType, flags As Integer, dataSize As Integer, data As IntPtr, callbackData As PlayRecordCallback) As Boolean 

Parameters

recordType

EmfPlusRecordType

Member of the EmfPlusRecordType enumeration that specifies the type of metafile record.

flags

Int32

Set of flags that specify attributes of the record.

dataSize

Int32

Number of bytes in the record data.

data

IntPtr

nativeint

Pointer to a buffer that contains the record data.

callbackData

PlayRecordCallback

Not used.

Return Value

Boolean

Return true if you want to continue enumerating records; otherwise, false.

Examples

For an example see EnumerateMetafile.

Remarks

This method is used in conjunction with the EnumerateMetafile method of the Graphics class. Certain overloads of the EnumerateMetafile method call an application-defined callback method of this type for each record in a specified metafile. The callback function can display each record (or selected records) by calling the PlayRecord method of the Metafile that is being enumerated.

A user declaration of this callback method must have the same parameters as the Graphics.EnumerateMetafileProc delegate declaration.
