Return values

newObject

Destination LPV object of the same type as the input.

Load()

LPVErrorCode Load

(

LString

filename

)

Load the LPV object from a specified file.

Parameters

[in]

filename

Full path of the file, it could be absolute or relative path with file name and extension.

Return values

error

Return error code if anything is wrong.

filename

)

Save the LPV object to a specified file.
The following lists all the serializable LPV objects and their supported extension:

LPV object	Extension	Contents
LImage	Image files (.bmp, .png, .jpg, .tif, etc.)	The image file.
Region objects	.droi	The region object's placement.
LLineDetector	.lld	The line detector's parameters.
LCircleDetector	.lcd	The circle detector's parameters.
LPathDetector	.lpd	The path detector's parameters.
LContourDetector	.ltd	The contour detector's parameters.
LCrossMarkDetector	.lcmd	The cross mark detector's parameters.

Load()

Valid()

BOOL Valid

(

)

Get whether this is a well-initialized LPV object, for example:

• A LImage object with an empty image is invalid
• A LRectRegion object whose placement is not set is invalid
• A LPolygon object without any vertex in it is invalid

Return values

Return

true for valid, false otherwise.
