Assembly:  MediaCy.IQL.Engine (in MediaCy.IQL.Engine.dll) Version: 10.0.6912.0
Syntax
VB
Copy
Function PutLine ( 
	vLine As Object,
	y As Integer
) As Integer

Parameters

vLine
Type: SystemObject
VARIANT : A VARIANT containing a SAFEARRAY containing the new pixel values. See GetLine for details.
y
Type: SystemInt32
long : The 0-based line number. Line 0 is the top line of the McRegionAccess.

Return Value

Type: Int32
Remarks
The y coordinate is relative to the McRegionAccess ROI, not the image. The pixel values returned are in the requested color model, which may differ from the image's native color model. If different, the pixel values will be converted back into the native color model and the image will be modified. This function supports region masking (see RegionMask). When a mask is set, PutLine will only set the values of pixels that lie inside the mask. If the FastAccess flag is on however, masking may not take place because the client will be directly access the image. Hence clients should turn FastAccess off when using region masking. See FastAccess for details. This is the preferred method for writing to an image.
