VISPOSX (Function)


Obtains an image process result (Coordinate X) from the storage memory.


VISPOSX (<Parameter>)


<Parameter>
Designates the number of the process result (Coordinate X) to obtain (0 to 511).
  • This is the same as when the VISGETNUM parameter is set to 1.
    VISGETNUM (n, 2) = VISPOSY (n)
  • The process results are different from the results stored with previous image processing instructions. Refer to the image processing instructions.
  • You can repeatedly obtain results because they are kept until the next image process instruction is executed,
  • If the previous image processing instruction designated an unexpected storage location, the value becomes an unknown number.
  • For this instruction, a µVision board (option) is required.
