VISGETNUM
(Function)
Obtains an image process result from the storage memory.
VISGETNUM(<Parameter 1>, <Parameter 2>)
<Parameter 1>
Designates the number of the process result to obtain (0 to 511).
<Parameter 2>
Designates the type of the process result to obtain (0 to 9).
-
The result contents stored change depending on an image process instruction executed in advance. Refer to the image process instructions.
-
The result is kept until the next image process instruction is executed; therefore, you can obtain the result as whenever you want.
-
The value becomes unknown if you designate an unknown storage with the image process instruction in advance.
-
For this instruction, a µVision board (option) is required.
