VISPOSY
(Function)
Obtains an image process result (Coordinate Y) from the storage memory.
VISPOSY (<Parameter>)
<Parameter>
Designates the number for the processing result (Coordinate Y) to obtain (0 to 511). An obtained value is represented as a single precision real type constant (F type).
-
This is the same as when parameter 1 of VISGETNUM is designated to 2.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 designates an unexpected storage location, the value becomes an unknown number.
-
For this instruction, a µVision board (option) is required.
