Cross

Creates a fixtured Cross structure.

The Cross function Functions are tools that are available in Spreadsheet for processing and analyzing acquisitions or other results. You can add functions to your Spreadsheet job to create tool chains and produce results for specific applications. has the following syntax:

Cross(Image, X, Y, Theta, X, Y, Angle, Width, Height, Show)

See the table for a description of the available parameters.

Parameter Description

Image

This argument must reference a spreadsheet cell that contains a valid Image data structure. By default, the cell referenced is cell A1, containing the Image data structure .

Fixture A fixture is a coordinate location on the image that keeps the tool in the place determined by the fixture.

Specifies the image coordinate system in which the cross is defined.

X

The X-offset of the origin, in fixture coordinates.

Y

The Y-offset of the origin, in fixture coordinates.

Theta

The rotation from the image X-axis, in the image coordinate system. (+/-360 degrees clockwise)

Cross

Specifies the size and position of the cross, in fixture coordinates.

X

The X-offset of the cross.

Y

The Y-offset of the cross.

Angle

Rotation from fixture X-axis.

Width

Width of the cross.

Height

Height of the cross.
Show

Specifies the display mode for the cross graphical overlay on the image.

0 = hide all (default)

The cross structure is not be displayed unless the cell containing the Cross function is highlighted in the spreadsheet.

2 = input graphics only

The cross graphic is always displayed.

Note: The Fixture and Cross parameters must be defined within the bounds of the image. Otherwise, the function returns #ERR.

Returns

A Cross data structure, or #ERR if any of the input parameters are invalid.

Results

When Cross is initially inserted into a cell, the following Structures Vision Data Access functions are automatically inserted into the spreadsheet to create a result table:

Label Function Description

X

GetX(Cross)

Returns the row offset of the center of the cross, in image coordinates.

Y

GetY(Cross)

Returns the column offset of the center of the cross, in image coordinates.

Angle

GetAngle(Cross)

Returns the orientation of the cross.

Height

GetHeight(Cross)

The height value.

Width

GetWidth(Cross)

The width value.
