Single ObjectName. CapGetFrameLeft(Integer Index)
Integer Index: specifies the value of which frame to get. The index is 0-based.
The data type of the return value is Single (float).
TRUE indicates success. FALSE indicates failure.
When an error occurs and IfThrowException property is TRUE, an exception will be thrown.
When FALSE is returned or an exception is thrown, check ErrorCode property and ErrorString property for error information.
The unit of CapGetFrameLeft() is determined by ICAP_UNITS capability.
The default unit is assumed to be "inches" unless it has been otherwise negotiated between the application and source.
CapGetFrameLeft() is different from ImageLayoutFrameLeft property.
CapGetFrameLeft() is part of ICAP_FRAMES capability negotiation. It can return the value of any frames in a page.
ImageLayoutFrameleft property only returns the value of the current frame which is being transferred. It is valid only in OnPreTransfer and OnPostTransfer event.
