TransformXY
Applies the calibration result and position correction amount to coordinate values.
Format
TransformXY <unitNo>, <imageNo>, <mode>, <srcX>, <srcY>, <destX>, <destY>
Parameter
Return value
None.
Description
Applies the transformation information specified in the <mode> parameter to the coordinate values specified
in the <srcX> and <srcY> parameters on the image specified in the <imageNo> parameter, of the processing
unit specified in the <unitNo> parameter.
Specify 0, 1, or 10 in the <mode> parameter. If a value other than 0, 1, and 10 is specified, operation after the
execution of this macro function will be undefined.
In the <destX> and <destY> parameters, specify the variables that will store the transformed coordinate
values.
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 is specified for a parameter,
an "Illegal function call" 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.
Parameter
name
Data type Description
<unitNo> Integer type
Processing unit number (0 to (number of processing units of current scene minus one)) of
the processing unit that holds the data to be converted.
<imageNo> Integer type
Measurement image number (always 0) of the processing unit that holds the data to be
transformed
<mode> Integer type
Transformation mode
0: After image transformation. -> Before image transformation.
1: Before image transformation. -> After image transformation.
10: Camera coordinates -> After calibration
