                           Image

Class that displays an image which can be scaled (upwards and downwards) and has interaction capability. The image can also be translated and rotated along the X, Y and Z axes.

Attention: Translating an image works differently (opposite) compared to translating a plane. For example, a positive translation along the z-axis moves a plane up. However, if the identical translation is applied on an image, the image moves down.

viewport (Viewport constant) - Viewport in which the image is to be displayed

Overrides: transform.TransformFilter.__init__

_isModified(self)

Return whether the Image has been modified.

Returns: Boolean: True or False

_render(self, scene)

Render the image.

Parameters:

scene (Scene object) - Scene in which the image is to be displayed
