DrawUnitImage
Display the "other unit image" on the image window. The "other unit image" refers to the held image by a
processing unit for the judgement reference.
Format
DrawUnitImage <unitNo>, <imageNo>
Parameter
Return value
None.
Description
Draw the image of the specified image number by the <imageNo> parameter that is held by the specified
processing unit number by the <unitNo> parameter.
If a non-existent number, numerical value, or combination of data types or values is specified for the <unitNo>
parameter, an "Illegal function call" error will occur.
Even if a value that does not exist is specified for the <imageNo> parameter, an error will not occur.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a value outside the range -2147483648 to 2147483647 is specified as an integer parameter, an "Overflow"
error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
Usage Cautions
• This macro function can only be used in the *MEASUREDISPI subroutine or the *MEASUREDISPG
subroutine. If used in another subroutine, an "Illegal function call" error will occur.
Example
Uses the *MEASUREDISPG subroutine of the Unit Macro processing unit to display image number 1 that is
held in advance by the advanced filter processing unit (Processing Unit number 5) and is allocated to output
image 1.
