Syntax
FUNCTION GdipCloneImageAttributes (BYVAL imageattr AS CONST GpImageAttributes PTR, BYVAL cloneImageattr AS GpImageAttributes PTR PTR) AS GpStatus
Parameters
| Name | Description | |
|---|---|---|
imageattr | [in] Pointer to the ImageAttributes object. | |
cloneImageattr | out] Pointer to a variable that receives a pointer to the new ImageAttributes object. |
Description
Makes a copy of an ImageAttributes object.
Example
' ======================================================================================== ' This example loads an image, creates an ImageAttributes object with a wrap mode, ' clones it using GdipCloneImageAttributes, and draws the same image twice using ' the original and cloned attributes. ' ======================================================================================== SUB Example_CloneImageAttributes (BYVAL hdc AS HDC)
DIM hStatus AS LONG
' // Create a graphics object from the device context DIM graphics AS GpGraphics PTR hStatus = GdipCreateFromHDC(hdc, @graphics)
