QMed_SetAreaImage

QMed_SetAreaImage(areaRef; imageRef):error
	areaRef	Longint	QMedical area reference
	imageRef	Longint	Image reference
	error	Longint	Error result

Assigns an image reference to a QMedical plug-in area.

The QMedical plug-in area is specified by areaRef. If areaRef is not a valid QMedical plug-in area reference, qmed_paramErr is returned.

Parameter imageRef must be a valid image reference created with the QMed_OpenImage command.

If the image is succesfully assigned, the area takes its ownership. This means that you don't have to call QMed_CloseImage to destroy the image reference; it is freed when the area is destroyed by 4D or when another command changes the area's content data.

Example

`Assign an image to a plug-in area

C_LONGINT($error)

C_LONGINT(gImageRef)

$error:=QMed_SetAreaImage (gAreaRef;gImageRef)

If ($error # qmed_noErr)
`Handle the error
End if
