Instance Method Details

↑ #explode ⇒ Object

The explode method is used to explode an image into a face with a texture on it.

Note that current versions of SketchUp will return an empty array here. To work around this limitation you can iterate over your entities collection to determine which new entities were created.

Versions prior to SketchUp 2015 returned an empty array due to a bug.

Examples:

model = Sketchup.active_model
path = "Plugins/su_dynamiccomponents/images"
image_file = Sketchup.find_support_file("report_tool.png", path)
image = model.active_entities.add_image(image_file, ORIGIN, 300)
entities = image.explode

Returns:

  • entitiesarray - an Array object of entities if successful

Version:

  • SketchUp 6.0

↑ #height ⇒ Object

The height method is used to retrieve the height of the image.

The height is given in inches.

Examples:

model = Sketchup.active_model
path = Sketchup.find_support_file "report_tool.png", "Tools/DynamicComponents/images"
pt = Geom::Point3d.new
entities = model.active_entities
image = entities.add_image path, pt, 300
height = image.height
if (height)
  UI.messagebox height
else
  UI.messagebox "Failure"
end

Returns:

  • height - the height of the model if successful

Version:

  • SketchUp 6.0

↑ #height=(height) ⇒ Object

The height= method is used to set the height of the image.

The height is set in inches.

Examples:

model = Sketchup.active_model
path = Sketchup.find_support_file "report_tool.png", "Tools/DynamicComponents/images"
pt = Geom::Point3d.new
entities = model.active_entities
image = entities.add_image path, pt, 300
UI.messagebox "Before adjustment"
height = image.height = 400
if (height)
  UI.messagebox height
else
  UI.messagebox "Failure"
end

Returns height - the new height if successful

Parameters:

    The height, in inches, to set the image.

Returns:
