This custom block adds a bitmap image to a CAD face and extrudes it normal to the surface to the provided height.

If you are experiencing noise around your image, try enabling the Smoothen option. When smoothing, decrease the Smooth Grid size and change Interpolation type to cubic for best results.
A good starting Color field is Grayscale. If your image has a lot of color, try a different color field — it may produce a better result.
The Centroid does not need to be exactly on the face; it acts as a rough guide for positioning.

Name	Type	Description
`CAD face`	brep_face	CAD Face to add the image to
`Body`	Implicit Body	Body that will have the added image
`Bitmap`	bitmap	The imported image to extrude
`Centroid`	Point	The image will be centered around this location. The centroid does not need to be exactly on the face, it acts a rough guide.
`Length`	Scalar	The Length of the image
`Width`	Scalar	The Width of the image
`Height`	Scalar Field	Height normal to the surface
`Color field`	Choice	A good starting field is the grayscale, but if your image has a lot of color, you may find a different color field produces a better result.
`Flip Image`	bool	If you notice your words are backwards, flip the image.
`Rotation Angle`	Scalar	Angle to rotate the image
`Inverse Image`	bool	Reverse which part of the image is shown
`Smoothen`	bool	If you are experiencing some noise around your image, you may want to try the smoothen option. If selecting “Smoothen”, we recommend decreasing the smooth grid size and change interpolation type to cubic.
`Smooth Grid size`	Scalar	Input used if you choose to smoothen the image
`Smooth iterations`	Integer	Input used if you choose to smoothen the image
`Interpolation type`	interpolation_enum	Input used if you choose to smoothen the image

Name	Type	Description
`Image on Face`	Implicit Body	Applying the image field to the implicit body
