The VI10ExtractDimension function allows to extract from the Buffer instructions, and the width and height of the VectorImage object.
This function of the always run after a VI10GetDimension command.
IMPLEMENTATION
VI10ExtractDimension (awBuffer, awWidth, awHeight)
Parameters:
| IN/OUT | VARIABLE TYPE | EXAMPLE NAME | DIM | |
|---|---|---|---|---|
| IN | ARRSYS / ARRGBL | awBuffer | W | Array that serves as a buffer for instructions/data |
| OUT | GLOBAL | awWidth | W | Variable containing the pixel width of the VectorImage object |
| OUT | GLOBAL | awHeight | W | Variable containing the pixel height of the VectorImage object |
Example
TASK_00
MAIN:
VI10InitBuffer(awBuffer)
VI10GetDimension(awBuffer)
VI10DrawBuffer(awBuffer)
VI11WaitBufferReadyUsingWAIT(awBuffer)
VI10ExtractDimension(awBuffer, awWidth, awHeight)
VI10InitBuffer(awBuffer)
END
Note
-
Before the command ExtractDimension you must have execute the VI10GetDimension command
-
After you execute the ExtractDimension command You must reinitialize the buffer with the VI10InitBuffer command
