Graphics.EnumerateMetafile Method (Metafile, Point(), Rectangle, GraphicsUnit, Graphics.EnumerateMetafileProc, IntPtr)
Sends the records in a selected rectangle from a Metafile, one at a time, to a callback method for display in a specified parallelogram.
Assembly: System.Drawing (in System.Drawing.dll)
Public Sub EnumerateMetafile ( metafile As Metafile, destPoints As Point(), srcRect As Rectangle, srcUnit As GraphicsUnit, callback As Graphics.EnumerateMetafileProc, callbackData As IntPtr )
Array of three Point structures that define a parallelogram that determines the size and location of the drawn metafile.
Rectangle structure that specifies the portion of the metafile, relative to its upper-left corner, to draw.
Member of the GraphicsUnit enumeration that specifies the unit of measure used to determine the portion of the metafile that the rectangle specified by the srcRect parameter contains.
Graphics.EnumerateMetafileProc delegate that specifies the method to which the metafile records are sent.
This method enumerates the records contained in the specified metafile. Each record is individually sent to a callback method specified by the callback parameter. Typically, the callback method calls the PlayRecord method to "play back", or draw, the record.
The destPoints parameter specifies three points of a parallelogram. The three Point structures represent the upper-left, upper-right, and lower-left corners of the parallelogram. The fourth point is extrapolated from the first three to form a parallelogram. The drawn metafile is scaled and sheared to fit the parallelogram.
Any drawing that takes place outside of the rectangle specified by the srcRect parameter is ignored.
