<Image variable>.EndDrawing (Function)

In french: <Variable Image>.FinDessin

Frees the image from memory.

Note: The call to <Image variable>.EndDrawing is optional. The resources are automatically freed when the window or the page is closed.

Caution: A specific configuration is required to use this function in Linux. See The drawings for more details.

Example

MyImage is Image = "Test.gif"
// Destruction of the image
MyImage.EndDrawing()

Syntax

<Image variable>.EndDrawing()

<Image variable>: Image variable

Name of Image variable to use.

Remarks

Use in object syntax

<Image>.StartDrawing must be called before using the drawing functions. <Image>.StartDrawing makes it possible to define the drawing options used on the Image control.

For an Image control:

The drawing functions operate on a copy ("bitmap") of the image. You can use the drawing functions of Windows (via API or CallDLL32) but these Windows functions must use the DC (Device Context) returned by <Image>.StartDrawing.
- <Image variable>.EndDrawing and <Image>.StartDrawing must not be called in the same process.
  The drawing will not be displayed if <Image variable>.EndDrawing and <Image>.StartDrawing are called in the same process: it will be automatically erased.
