_WinAPI_GetWorldTransform

Retrieves the current world-space to page-space transformation.

#Include <WinAPIEx.au3>
_WinAPI_GetWorldTransform ( $hDC )

参数

$hDC Handle to the device context.

返回值

Success $tagXFORM structure that contains the current world-space to page-space transformation.
失败: 返回 0 并设置 @error 标志为非 0 值.

注意/说明

The precision of the transformation may be altered if an application calls the _WinAPI_ModifyWorldTransform()
prior to calling _WinAPI_GetWorldTransform(). This is because the internal format for storing transformation
values uses a higher precision than a FLOAT value.
