DrawBox
Draws a rectangle on the image window.
Format
DrawBox <x0>, <y0>, <x1>, <y1>, <imageNo>[, <unitNo>]
Parameter
Return value
None.
Description
On the measurement image whose specified image number is in the <imageNo> parameter, draws a
rectangle that has the specified upper left vertex coordinates by the <x0> and <y0> parameters and the
specified lower right vertex coordinates by the <x1> and <y1> parameters.
Specify the corresponding Unit Macro processing unit number in the <unitNo> parameter to draw the image
at the position coordinates before applying position compensation. If the <unitNo> parameter is omitted, the
image is drawn at the position coordinates after applying position compensation.
In the <x0>, <y0>, <x1>, and <y1> parameters, specify the camera coordinates whose origin is at the upper-
left corner of the image.
Normally 0 should be specified in the <imageNo> parameter.
In the <unitNo> parameter, normally specify the processing unit number of the Unit Macro processing unit
that executes this process.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a non-existent number, numerical value, or combination of data types or values are specified for a
parameter, an "Illegal function call" 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.
Parameter
name
Data type
Description
<x0>
Integer type
The upper-left corner X coordinate of the drawn rectangle
<y0>
Integer type
The upper-left corner Y coordinate of the drawn rectangle
<x1>
Integer type
The lower-right corner X coordinate of the drawn rectangle
<y1>
Integer type
The lower-right corner Y coordinate of the drawn rectangle
<imageNo>
Integer type
Measurement image number to draw on (always 0)
<unitNo>
Integer type
Processing unit number that executes the drawing processing (0 to (the number of
registered processing units in the current scene minus one))
