Syntax

FUNCTION IsInfinite (BYVAL pGraphics AS CGpGraphics PTR) AS BOOLEAN

Parameters

Name		Description
`pGraphics`		Pointer to a Graphics object that contains the world and page transformations required to calculate the device coordinates of this region.

Return value

If this region is infinite, this method returns TRUE; otherwise, it returns FALSE.

Description

Determines whether this region is infinite.

Example

' ======================================================================================== ' The following example uses the default constructor to create an infinite region. Then the ' code tests the region to determine if it is infinite and performs a task based on the result. ' ======================================================================================== SUB Example_IsInfinite (BYVAL hdc AS HDC)

' // Create a graphics object from the window device context DIM graphics AS CGpGraphics = hdc ' // Get the DPI scaling ratios DIM rxRatio AS SINGLE = graphics.GetDpiX / 96 DIM ryRatio AS SINGLE = graphics.GetDpiY / 96

graphics.SetPageUnit(UnitInch) DIM solidBrush AS CGpSolidBrush = ARGB_RED

' // The default constructor creates an infinite region. DIM region AS CGpRegion

IF region.IsInfinite(@graphics) THEN

' // The region is infinite. Perform some task.
  PRINT "Region is infinite"

ELSE

' // Perform a different task.

END IF

graphics.FillRegion(@solidBrush, @region)

END SUB ' ========================================================================================
