# Colorize

Colorizes a grayscale image. The color palette is the same as in the 3D view. Returns an Image data structure.

## Colorize Inputs

Setting | 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 | Defines the Region of Interest (ROI) relative to a Fixture input or the output of the image coordinate system for the Vision Tools function. Setting the ROI relative to a Fixture ensures that if the Fixture is rotated or translated, the ROI is rotated or translated in relation to the Fixture. Note: 2D projections use real world units but fixturing with 2D tools requires input in pixel values. When using a 2D projection from a 3D point cloud as a Fixture, convert the real world units to pixel values using the TransWorldToPixel function. The default setting is (0,0,0), the top leftmost corner of the image.
X | The X-offset, in image coordinates.
Y | The Y-offset, in image coordinates.
Theta | The rotation from the image X-axis, in the image coordinate system. (+/-360 degrees clockwise)
Region | Also known as the Region of Interest (ROI), specifies the region of the image that undergoes analysis. Double-click on the Region parameter to create an Interactive Graphics Mode that you can transform and rotate. Select this parameter and press the Maximize Region button on the Job Edit toolbar of the property sheet to automatically stretch the region to cover the entire image.
X | The X-offset of the origin, in fixture coordinates.
Y | The Y-offset of the origin, in fixture coordinates.
Width | The dimension along the Y-axis of the region.
Height | The dimension along the X-axis of the region.
Angle | The orientation, in fixture coordinates.
Show | Specifies the display mode for DetectBlobs graphical overlays on top of the image.
0 = hide all (default) | All graphics will be hidden, except when the cell containing the DetectBlobs function is highlighted in the spreadsheet.
1 = result graphics only | Blob outlines will be displayed at all times.
2 = input and result graphics | Both the input image region and the outlines of extracted blobs will be displayed at all times.

## Colorize Outputs

Returns | An Image data structure.
